ngier
March Perkins (1799 - 1881) engineer,
inventor, author and
patentee, was named after his uncle Angier March and the second
surviving son of
Jacob and Hannah Greenleaf. Born in
Newburyport, Massachusetts USA on the 21st
August 1799. He sailed for England and arrived in December 1821,
and thereafter for
some time was associated with his father in perfecting his method of
engraving
bank-notes, and also of using steam under very high pressure. Following
the
subject of high pressure steam he developed and patented a method of
warming
buildings by
means of circulating hot water through small diameter pipes in a sealed
system.
The first building to be heated by this type of system was in the
horticultural hot-houses at the house of John Horsley Palmer (the then
governor of the Bank of England) in Fulham London in 1832. This method
of heating came into extensive use and was the foundation
of a
large business carried out first in Harpur Street, which then moved
into Francis
Street and finally into Seaford Street, Grays End Road. He
inherited
much of his father’s talents for
inventions and like his father before him he took out many patents
between the
years 1831 and 1864. BP 6146, 8311 and 8804 all relate to the high
pressure hot
water method of heating and subsequent improvements. His patent in 1843 for the manufacture of
and
melting of
iron by
the use of superheated steam was remarkable insomuch as it evidently
contained
in it the ideas of the subsequent discoveries relating to
the
conversion of
iron into steel, and the elimination of phosphorus and sulphur from the
iron. His attention to detail combined with his inventive powers rendered a great service to the mechanical world. Few of his inventions were the subject of patents, but the left and right hand thread screwed joint which was patented by him, has to be admitted to have been essential in its use for hydraulic work. As a method of joining two pipes together and forming a sealed joint capable of bearing the same pressure as the pipe itself shows it to be both simple and effective. In later years the system of circulating water in a sealed system, heated up to 2000 psi pressure was applied to the heating of baker’s ovens. This method was extensively adopted, as it possessed the advantage of being easily regulated. It was patented in 1851 BP 13509 and was later much improved. He was elected the 587th member as an
Associate of the Institution of Civil
Engineers on the 5th May 1840. He married Julia Georgiana
Brown in 1831 and they had four children, Angier Greenleaf, Loftus, an
unknown daughter and Louisa Jane.
In the
census
of 1881 he is recorded as living in Hampstead London
with his son Loftus and his wife
Emily, and their two children Loftus Patton jnr. and Ludlow Patton.
Angier died on the 22nd April 1881 in Hampstead London at the age of 81 and is buried in Kensal Green Cemetery London. |

oftus
Perkins
(1834 - 1891) engineer,
author, inventor and patentee was born on
the 8th May 1834 in Great
Corham Street, Russell Square, London.
At a very early age he entered his fathers manufactory and during 1853
– 1854
he practised on his own account as an engineer in New York. Returning to England he remained with his
father for 8 years until 1862 working on the steam gun and other
inventions.
From 1862 until 1866 he was in business on his own in Hamburg and
Berlin
designing and installing many systems for warming buildings in various
parts of
the continent. Returning to England in 1866 he entered into partnership
with
his father and worked on the design and construction of steam engines,
boilers
and especially in developing the use of high pressure steam as applied
to steam
engines. The partnership continued until his father’s death in 1881. He inherited much of the inventive capacity of his father and grandfather, and from 1859 onwards took out a very large number of patents. The main subjects to which he directed his activities were the use of high pressure steam as a motive power, and the production of artificial cold.
"He was a man with brown eyes, well proportioned in build and a great chemist and engineer. He had a large moustache and Dundreary whiskers, who always wore a double-breasted blue suit, and in the Works, a peaked cap with silk oak leaves around. In the winter he used to wear a Canadian fur cap. He came into the Works one Sunday morning dressed in white flannels with a white peaked yachting cap. He smoked 13 ounces of tobacco a week - he always carried a pouch with 4 ounces of tobacco in it. His type of tobacco was "Branksome's Light Virginia". In conjunction
with his friend Dr
Williamson he took out three patents in 1859 and 1860 for surface
condensers,
steam engines and boilers. In one of which he says “Our chief object is
to
employ steam of very high pressure; as for example of 500 psi. or more
or less
and to expand this steam several times, and then condense it so as to
obtain a
great amount of power from a small quantity of steam”. He devoted many
years of
his life to this subject. His labours in this subject are shown in two
papers
read before the Institution of Mechanical Engineers in 1861 and 1877
and
published in the “Proceedings” for those years. Among
his many inventions is his patent in 1867 for water meters,
and one in 1868 for wrought iron metal wheels, the spokes of which
consisted of
hollow bars or tubes screwed into the nave or tyre. A large number of
gun
carriage wheels were constructed using this principle for the
Government, and
though they stood the most severest of tests nothing more was heard of
this
invention.
Another of his
inventions described in 1891 in Fletcher's book "Steam Engines on
Common Roads" says, His yacht Anthracite, constructed in 1880 was fitted with engines working with steam at a pressure of 500 psi. and it is probably the smallest ship of that time ever to have crossed the Atlantic steaming the entire distance. The Perkins engine company published a number of reports upon her performance, drawn up respectively by Sir Frederick Bramwell, by a committee of officers of the U.S. Navy and by Sir Frederick Bramwell and Mr William Rich conjointly. He continued with the experiments which had occupied the attentions of his father and grandfather which was the production of artificial cold which resulted in the “Arktos” a cold chamber suitable for preserving meat and other items of food. It was based on the separation of ammonia gas from the water in which it is dissolved, the liquefaction of the gas, and the subsequent revapourisation of the ammonia, with the reabsorption of the gas by the water. This was his last great work, and his unremitting attention to it inevitably caused a breakdown in his health. He became a
Member of the
Institution of Mechanical Engineers in 1861 followed by Membership of
the
Institution of Civil Engineers in 1881. Loftus died on 27th April 1891 at his home in 148 Abbey Road Kilburn London at the relatively young age of 57. Compared with both his father (82) and grandfather (83), maybe, just maybe, his addiction to tobacco and his heavy pipe smoking compounded by the stress of his great work load contributed to his early death. His Will was proved on the 28th May 1891 in the sum of £1829. A very modest sum when considered against the inventions, patents and other business interests he achieved during his working lifetime. He was survived by his wife Emily and their two sons Loftus Patton and Ludlow Patton. Both of his
sons worked in their fathers business
which by then had been made a limited company.

oftus Patton Perkins (1868
- 1940) the eldest son
of Loftus was born in Kilburn London in 1868 and
followed the
engineering path of his father working in his business. In the 1901
census Loftus then
aged 33 years is recorded living with his wife Henrietta in
Willesden London, and giving his
occupation as Mechanical Engineer. He died in 1940 in London, aged 72
years.
Loftus possessed other talents
and was an accomplished artist as the watercolours shown below
beautifully illustrate. The watercolours titled London Bridge painted
by him in 1933, and Thames Barges painted in 1926, opens up a new line
of research for the Group to
determine whether he was well known as an artist in that time period,
and to establish also if there are other paintings by him, that still
exist.

udlow Patton Perkins (1873 - 1928) the second and youngest son of Loftus was born in Kilburn London in 1873 and followed the engineering path of his father working in his business, which by the time of the death of his father had become a limited company. He moved to Lancaster in the year 1902 having previously lived in Manchester where he was for a number of years associated with Hy Wallmark and Co Ltd and also with Joseph Adamson and Son, of Hyde in Cheshire with whom he was interested in the high pressure stopped-end tube boiler. His speciality was steam at very high pressures and on this subject he was very authoritative. He was a director of the Lune Valley Engineering Company Ltd of Lancaster and later practised as a consulting engineer, devoting his time and energies to the development of refrigerating apparatus. In conjunction with William Edward Buck, Engineers of
Carisbrooke, Battershall, Worcestershire
they applied for and were
granted British Patent No. 22272 dated 1892 titled "Improvements in
devices for the diffusion of transference
of heat” This patent gave
improvements to the basic Perkins tube which had previously been the
subject of
earlier patents taken out by his grandfather Angier M Perkins and
great-grandfather Jacob Perkins dealing with hermetic single phase and
two
phase heating tubes.
In the 1901
census Ludlow then
aged 28 years is recorded as living at 21 Herbert Street, Moss Side,
Manchester, giving his occupation as Mechanical Engineer.
Coincidentally, residing at the same address is George F Buck. who was
probably
related
to the William Edward Buck with whom Ludlow made the patent application. He died on 18th
October 1928 at Lansdowne House, Regent Street, Lancaster at the early
age of 56 years. |

The Perkins HPHW Heating System |
In the early 1800’s in pre-Victorian Britain central heating systems were slowly coming into fashion with steam or warm air always being used as the heating medium. The use of hot water as an alternative form of heating medium had not yet been considered.
In 1827 an American family named Perkins arrived in this country from Massachusetts USA. Jacob Perkins (1766 – 1849) and his son Angier March Perkins (1799 – 1881) both with their families. Jacob and Angier were Engineers and inventors who had already experimented with using hot water in sealed pipework systems to create heating systems capable of operating at high temperatures and pressures.
Angier Perkins continued this research with his experiments in England and by 1831 was ready to apply for a patent for his invention. His first British Patent 6146 dated 30th July 1831 was listed as “Apparatus for heating air in Buildings” which was to be the first of many. This new method of central heating was to circulate hot water through small diameter pipes at high temperatures and pressures. The Perkins Patent for their heating system was considered an ingenious and useful invention by the Privy Council who on the 10th March 1845 granted a five year extension of the Patent, from the termination of the present Patent.
This new development in the heating of buildings quickly found favour with businesses and the aristocracy. During the 1830’s many of these systems, which had then become known as “The Perkins System”, had been installed in buildings throughout the country. The Lists of Contracts ranged from Public Buildings, Private Mansions, Churches, and Manufactories to Hothouses, Greenhouses and Conservatories, in towns and cities as far apart as the Isle of Wight to Edinburgh and Ireland.
The system is simple in its design and is formed as an endless loop of pipe, part of which is coiled around inside a brickwork furnace. The pipework is hydraulic quality tubing with the system closed and sealed. Sealing the system allowed it to operate at working pressures of up to 300 pounds per square inch and temperatures as high as 300°F.
Isometric layout of 2- circuit pipework distribution systemThe system used gravity as the means of circulating the hot water around the pipework. The length of each circuit was therefore limited by the small diameter pipe size and needed to be kept to a maximum of 500 feet. Up to 15 per cent of this circuit was coiled inside the brickwork furnace. Should this length of pipework not be sufficient for the heating of the building then the endless loop was made longer in multiples of 500 feet with each circuit length returning to the brickwork furnace.
Each sealed circuit needed to be fitted with an expansion tube which had to be fitted at the top (the highest point) of the system. These closed expansion vessels allowed the heated water to expand into the vessel from the bottom and compress the air inside the vessel, thus exerting an artificial pressure on the water. Most systems were initially filled from the bottom of the pipework circuit until the top-up fill point was reached.
![]()
The tubing used is of small size approx. 1" outside diameter with the lengths of tubing joined together with right and left hand threaded pipe sockets. The sockets were of unusual design in that no jointing material was needed. The sockets used a metal to metal joint with one end of the threaded tube being chamfered. This was then pulled tight up to the flat faced end of the other length of tube.
THE TIMES NEWSPAPER ARTICLE
The Perkins high pressure high temperature (HPHW) hot water heating system did however have some problems early in its life. These are quite forcibly described in a letter written to the editor of THE TIMES newspaper which appeared on Saturday 20th November 1841. The letterwriter supplies a list of buildings which details a number of them that had experienced fires supposedly caused by direct contact with the very high surface temperatures of the pipes.
Wilson.Casey and Phillips, Spitalfields - Warehouse set on fire by pipes becoming red hot
Sir Hussey Vivian. Glynn House -ditto-
Mr Barbour Manchester -ditto-

Why these systems went out of fashion is most likely to have been the increasing popularity of low pressure hot water heating systems which had greater flexibility to suit the more complex buildings of the 20th century. The discovery of the reason for the likely cause of its fall from grace still remains a matter of interest to the author. Another possible reason could be, that insurance companies were increasing their premiums for insuring this type of system due to the incidence of fires caused, or maybe they were even refusing to provide cover.
It states in the letter to The Times “It is a subject which alike concerns the fire insurance companies as well as individuals; and it is a well known fact, that since the commencement of the present year, in consequence of the fires which occurred in Manchester, as already stated, many insurance companies both in London and in the country have refused to insure at any premium whatever buildings heated by some of the plans which have been here described”
Looking at the list of buildings damaged, one of the buildings mentioned was the Guardian Fire Office, and this could not have been good news for the Perkins company. However, these problems must have been overcome as Perkins’s systems were still being installed into the 1890’s and beyond.
However, Angier March Perkins responds to the letterwriter's allegations giving a robust defence of his invention of the High Pressure heating system.

Several of these Perkins HPHW systems installed in the Victorian era survive to this day. They are all to be found in Churches and Chapels located in the south of England and South Wales. The fact that these systems installed during the 19th century are still heating their original buildings in the 21st century is a lasting tribute to the innovative design of their inventor Angier March Perkins.
Although these systems were originally designed to operate at high temperatures, with today’s lower acceptable temperature limit requirements for exposed pipework, and the introduction of pumped circulation and temperature controls, their flexibility of use has allowed them to remain in operation for over 160 years.
Truly a most remarkable achievement.
Churches that have been discovered in England which
are still heated with a Perkins HPHW System
St Michael’s & All Angels. Bampton Devon St John the Baptist. Yarcombe Devon
St John the Baptist. Newport Devon St Margaret's Northam Devon
St Mary’s. Bruton Somerset St Mary’s. East Brent Somerset
St John the Baptist Halse Somerset St Peter's Broadstairs Kent
St Stephen Winsham Somerset St Michael the Archangel. Mere WiltshireThree of the churches in Devon are made even more remarkable because the Perkins systems have remained as originally installed including the brickwork heating furnace, and still using gravity water circulation. The furnaces were initially solid fuel fired but have now been converted to oil firing.

It is of defining interest to discover that the Perkins type of sealed system found in these churches were installed by so many different heating firms, all using the same HPHW design principle.

It was known
that the Perkins family were not interested in installing their
Patented heating systems but must have found it financially acceptable
collecting royalties, to allow other firms to manufacture both the
tubes and fittings and
carry out the installation of the HPHW heating system. They may well
have
allowed smaller firms to simply install the system after purchasing the
material from another manufacturer. The firm of Renton Gibbs Liverpool
carried out numerous installations of HPHW heating systems in
Churches throughout Radnorshire and
Herefordshire at the end of the
19th century, based on the design
of the Perkins system.
An estimate and
invoice submitted by J Longbottom & Co of Leeds has
been found in the archives of the Wiltshire Record Office. It is for
the installation of a Perkins system in the Parish Church of
All
Saint's, Liddington Wiltshire, in the year 1901. The estimated cost for
the
supply
and
erection of
the complete heating system is the princely sum of £58.00.
A visit made to the church found the pipework system to have be removed many years ago. The only remaining item from the original system in the basement was the furnace complete with its 3 pipe circuits and the cast iron firing doors with their Longbottom inscription. ![]() Wiltshire Record

It was most surprising to discover that in the numerous Churches and Chapels which were built in South Wales during the second half of the 1800’s a great many were heated by the Perkins pressurised system. Most of these systems are still operating as originally installed using gravity circulation to distribute the water around the endless loop of pipework.
Both the high pressure type of system using expansion pipes and the medium pressure type using a cold water feed tank with an integral relief valve, have been found installed in these church / chapel buildings.
The population in the Welsh valleys increased dramatically from the 1840’s onwards. Demographic changes were brought about by the influx of people wanting to work in the new industries of coalmines and steel works that were being opened. At the same time as this growth in population was occurring ecclesiastical buildings to suit all religious denominations were being constructed.
Various researches carried out so far have been unable to identify names of the original firms who installed these Perkins heating systems during the 1800’s. Only one instance has recently been found of an original installer. That was Musgrave's of Belfast c.1890 at All Saint's Church in Llanelli, Carmarthenshire.
We do know that these firms bought the hydraulic quality tubing and fittings that were required, and then designed each heating system deciding upon the number of heating circuits that were needed to form the endless loop, which had to satisfy the heat loss of the building. They fabricated and shaped the tubing to suit the layout for each section of the circuit, so that the pipework could then be assembled in situ including the proportion of each circuit that had to be fitted inside the brickwork or iron furnace. As a rough design rule of thumb 1 foot of furnace tube gave out 1000 Btu's / hour.
By the early decades of the 20th century many of the original brickwork furnaces and iron furnaces were in need of renewal and this refurbishment work was carried out by local firms such as F P Hurley’s and J C Hitt's of Bridgend also Algers of Newport. On occasions the Northern Ireland firm of Musgrave’s came to South Wales to install Perkins systems.

The only other type of assembly fitting used in the pipe circuit was a screwed pipe cap which was fitted at positions such as the fill and expansion points. Again it was necessary for these fittings to be able to withstand the high working pressures. Special long spanners were needed to apply the torque needed to tighten these pipe caps.

One additional item of pipeline
equipment has been found that seems to
be particular to the systems found in South Wales. Made from
cast brass these items are purpose made air vents. They are either
fitted with thumb turn screws as shown in the picture, or with
square headed screws for use with a special spanner. One possible
reason
for these air vents being required is that most of the chapels and
churches have balconies and the pipework circuits are routed at two
levels. This
made flush venting of the system difficult to carry out, so another
means of venting was needed to allow the air to escape. Hence the
need for air vents. |

The following article is taken from the Gardener Magazine written only months after Angier March Perkins had received in 1831 the patent for his new mode of heating. It is therefore an indication of how this new method of heating was attracting wide interest in the horticultural world.
This is one of the most extraordinary improvements that have yet been made in heating by this fluid. The advantages which are expected to result from it are, great economy in the first erection as there is no boiler, and the pipes in which the water is circulated are not thicker than a man’s thumb, a power of conveying heat to a greater distance than by any mode hitherto in use; of producing a much higher temperature than has hitherto been done by either water or steam even to the extent of 400º or 500º; lastly a more universal applicability of hot water as a medium for conveying heat.
The words of Mr Perkins patent are “……The object of my improvements is to obtain considerably higher degrees of temperatures to the water circulated, and thus I am enabled to apply my apparatus to a variety of purposes which require the heating medium to be at a degree of temperature higher than that of boiling water. And my improvements consist in circulating water in tubes or pipes which are closed in all parts, allowing a sufficient space for the expansion of the water contained within the apparatus, by which means the water will at all times be kept in contact with the metal, however high the degree of heat such apparatus may be submitted to, and yet at the same time, there will be no danger of bursting the apparatus in consequence of the water having sufficient space to expand …..”
Mr Perkins has employed his mode of heating in the Bank Of England, in his own manufactory in Fleet street, in some other houses and manufactories in London, in the Elephant House at the Zoological Gardens in the Regents Park, a range of Hothouses at Mr Palmers, Parsons Green Fulham.
We have seen the apparatus at work both in the Zoological Gardens and at Mr Palmer’s and we are so highly satisfied with the plan that we shall have our hothouses and Greenhouses heated by it before this magazine sees the light.
It was our intention to employ Witty’s Smoke Consuming Furnace to heat water which we intended to circulate by the syphon mode; but Perkins method will not cost above a third of the expense which this would have led us into and what is an object in all small green-houses it occupies very little room.
Perkins fireplace is also calculated to consume the greater part of the smoke; not perhaps so completely as Witty’s but still much more so than by any other mode, hitherto brought into notice which can be applied upon a small scale. To Gentlemen residing in the country, Perkins mode of heating presents an additional advantage in point of economy; and this is, that the pipes being small and consequently light (in comparison with the cast-iron pipes 4 ins or 6 ins diameter usually employed), can be sent to any distance by coach; while the mode of joining them being entirely mechanical, they may be put together by any person who can use a screw-wrench.

OPERATING AND
MAINTENANCE INSTRUCTIONS
|
The Heritage Group have been very fortunate to be given an old Perkins system maintenance instructions information card which was originally displayed in the furnace room of a building. These instructions have been prepared by the firm Alger's of Newport who were responsible for the installation and refurbishment of many Perkins HPHW heating systems. The transcription of the maintenance instructions is as follows.
INSTRUCTIONS
FOR THE MANAGEMENT OF R. ALGER & SONS’
IMPROVED HOT WATER HEATING APPARATUS
BEFORE LIGHTING THE FIRE DAILY.
1, Thoroughly clean out the fire box and flues of furnace and the ash pit.
NOTE. – It is impossible to obtain the heat with a dirty fire-box; a dirty ash pit may cause the fire bare and plates to burn out in a few hours.
2. Fill apparatus thus:- remove cap from air pipe on expansion tube first, then cap from filling tube ( NB – Caps must not be changed); add water as required, replace cap on filling pipe then on air pipe. It will suffice if this is done weekly : Note - the apparatus must be thoroughly cold when this is done. If there is more than one expansion, all caps all caps must be taken off before filling in water and the water must always be allowed to settle.
3. If apparatus is fitted with tank and valve, valve must always be covered with water. A line is painted on tank below which level the water must not fall when apparatus is cold. It would be well for attendants to examine valve every 2 or 3 weeks to make quite sure that both top and bottom valves are working freely and to lubricate valves with Vaseline. Note - the apparatus must be cold when this is done.
TO MAINTAIN TEMPERATURE
1. Add fuel as required
2. Keep the bars free from clinker. Keep the ash-pit thoroughly clean.
3. Keep a window, door or ventilator leading to the furnace room always open, so that the air can freely get to the fire.
GENERAL INSTRUCTIONS
1. Never touch the caps on air pipe and filling pipe while the apparatus is at work.
2. If the fire is to be maintained during the night, nearly close the damper and the ash pit door and charge the furnace with small broken coke.
3. If there is a tendency to down draught when lighting the fire, warm the flue by burning paper or shavings close to the nearest cleaning door.
4. During FROSTY weather the fire must be kept in DAY and NIGHT. If FROST has occurred since the fire was last lighted it must not be lit again until you have made quite sure that neither the boiler nor pipes are frozen otherwise it might cause an explosion.
5. A knocking noise in the pipes while heating or cooling indicates the presence of air, and the necessity of the apparatus being re-charged, in such case apply at once to the manufacturers. Noise in the pipes is sometimes caused by having a very small bright fire in furnace and then filling up with new fuel. To stop this only add a little new fuel at a time until it burns brightly, afterwards fill up. It is also caused by having a very fierce draught when the fire is burning strongly. To prevent this reduce draught by partly closing damper and ash pit door. Any defect in the furnace should be repaired immediately.
6. Any leak must be immediately stopped.
7. In the event of any repairs or alterations being required, no one unaccustomed to this form of apparatus should be called and if tampered with by inexperienced men damage can be easily done, and useless expense thereby incurred.
8. These systems should receive attention and circulations re-charged hydraulically every two or three seasons.

A second Operating & Maintenance Instruction Leaflet was given to the Heritage Group which interestingly covers what Perkins called their Medium Pressure Heating System. This uses a cold water storage cistern as the fill and expansion device. Two expansion relief valves are fitted within the cistern.

SUPPLY OF WATER
1. It is most important to attend to the supply of water, as the working of the apparatus depends on it. The expansion cistern (A) should be kept two-thirds full of clean soft water; the water when heated, will rise or expand one or two inches, and will fall to the first level when it cools. The cistern should be occasionally examined by the person in charge of it (say once a fortnight), to see if the water is alright and that the valves are in proper working order. The weight on valve (B) in the cistern and the under valve (C) must not be touched when the fire is on. They should be kept clean, so as to rest on their seats, and touched occasionally to prevent them getting gagged. This must only be done when the fire is not lighted.
2. Should the water rise high, or overflow in the cistern (A), it shows that the furnace is over-heated, or the valves out of order – when it should be immediately cooled, and the cistern examined.
3. The cistern and water should be kept clean, the dirty water being drawn off by the cock at the bottom, two or three times a year.
HOW TO REGULATE THE FURNACE
4. In lighting the fire at first, the furnace should not be loaded with fuel before the circulation of the water has commenced, which is known when the flow pipe (F) feels hot to the hand.
5. When the fire is well lighted, fuel should be gradually put into the furnace, taking care never to fill it up so as to choke the openings in front of the coils; and by feeding it as required, a regular heat will be maintained. To ensure a good draught the furnace bars must be kept clear. The draught must be carefully regulated by damper (D) and the ash-pit door (P), to prevent overheating of the pipes. Should the draught become bad, it shows that the furnace flues, or the vent, are obstructed by soot, which should be removed.
