Tortoise stove

Tortoise stove

17 December, 2006
The Tortoise stove dates from 1830, when the first was hand-built by Charles Portway to heat his ironmongery store in Halstead, Essex. After making a second stove for a neighbour, Mrs Portway suggested he go into business manufacturing and selling them, so he established a small foundry and went to work.

The hypocaust

17 December, 2006
This underfloor heating system is said to have been devised by the Roman Sergius Orata in about 80 BC and was described by Vitruvius in his book De Architectura in 16 BC. Hypocaust heating was used by the Romans in their villas throughout the colder climates in Europe and Britain as they expanded their Empire. This was the first widespread central-heating system and remained in use throughout much of Europe for over 400 years. It is, at last, enjoying a revival.
Lancashire boiler

In 1698, Savery produced a steam boiler to operate ‘The miner’s friend’, a water pump used in mines. In 1705, Newcomen and Cauley designed a boiler to drive Newcomen’s steam engine. By 1725 the Haystack and Wagon boilers were in common use and held their place for the next 70 years or so. They all had one thing in common. They were inefficient because the boiler sat above the fire, and much of the heat and hot gases never came into contact with the water-backed surfaces.
Sturtevant fan

Primitive wooden fans are depicted in 16th century German woodcut illustrations showing mine ventilation methods. These paddle-bladed fans were enclosed in a square wooden casing and cranked by hand or driven by windmills. A hand-cranked fan was installed in the House of Commons in 1736, but the forerunners of today’s centrifugal fans only appeared from the mid-19th century.

The Gurney stove

17 December, 2006
Goldsworthy Gurney (later Sir) was born in Cornwall in 1793. In 1814, he settled in Cambourne where he practised as a surgeon, moving to London in 1820 and developing his interest in engineering. In 1825 he patented a steam carriage, going on in 1842 to patent a system of heat recovery from lighting fittings. In 1852, Gurney was appointed to investigate the ventilation problems in the House of Commons where he flashed off large quantities of gunpowder in the chamber to observe the motion of the air currents, He was said to have posed a greater risk than Guy Fawkes!

The Grundy stove

17 December, 2006
John Grundy Senior was born in Tyldesley near Manchester in 1807. He was a grocer and flour trader. He was a warden of the local Top Chapel. When the chapel needed a heating system he developed and installed a revolutionary warm-air heating stove with an arrangement of plenum and discharge ducts. This was so successful that in 1859 he set up in business to manufacture and market his heating apparatus, which he later patented. The business flourished and he continued to make improvements, increasing its efficiency and effectiveness, and securing more patents. He died in 1879.

Electric thermostat

17 December, 2006
Even the cave man who rubbed two sticks together knew that he needed some control over his fire. He got fed up lugging logs from the forest just for his missus to fling the goatskin door open to cool down! Fire was therefore rationed to conserve energy, which is pretty much what a thermostat now does. Without control, we squander precious resources or use our fabulous machines to exhaustion.

Hartley & Sugden boilers

17 December, 2006
In the 18th century the development of boilers was directed towards raising steam to drive steam engines. Around 1810, systems of heating by hot water were introduced. Early hot water heating boilers were small and crude, and heating for buildings such as country houses, churches and prisons continued to be mainly by warm air. Most early hot-water boilers were of the saddle type, originally manufactured using rivetted wrought-iron plates. Steam heating for other than factories and large institutional buildings, such as hospitals and asylums, never achieved great popularity.

Haden stove

Haden stove

17 December, 2006
In 1797 the brothers George, James and John Haden, with their father George Senior, were working at the world-famous firm of Boulton & Watt at the Soho Manufactory in Birmingham. The brothers all worked for the Engine Company. After serving their apprenticeships George and James worked as erectors for the improved steam engine of James Watt. In 1814 George went to Trowbridge for the firm, later being joined by James. In 1816 the pair formed their own company of G&J Haden to act as agents in the West Country for Boulton & Watt.
Jacob Perkins was born in Massachusetts in 1766. In 1816 he moved to England and secured a number of patents relating to boilers, steam engines and, most notably, a vapour-compression refrigeration machine.

It is the use of Mitsubishi Electric ground-source heat pumps that led to the building winning the Cooling Industry Awards this year.

Delivering greener buildings

16 December, 2006
‘Greenness’ cannot easily be added to a building at a late stage in the design process. The reduction of carbon emissions must be considered from the very beginning, and building-performance simulation software is an important tool. DAVID McEWAN explains.
