HEATING SYSTEMS

Rule-of-thumb methods were in use until quite recently for ascertaining the number of units required to heat a building, but to-day great savings are being effected, and much better results are being achieved through the application of scientific principles in tlie type of boilers ami other apparatus, and their arrangement in accordance with tests carried out over a long period. For these, so far. as Great Britain is concerned, the British Institute of Heating and Ventilating Engineers has been responsible, and what was formerly guesswork is now largely a science. Glass, wall, roof, and floor surfaces are now all taken into consideration in computing tlie heat losses, in order to ascertain the type of boiler required and the fuel consumption. 'fests have also been carried out With radiators and boilers, and the Institute has been responsible for a complete system of rerating. This has resulted in much greater reliability.

One of the latest methods of heating is by the panel system, which is really a modern adaptation of tlie old Roman methods. Pipes are bedded in the plaster, and no radiators are to be seen in the room. Heating by atmospheric steam has also undergone great improvements, and indirect heating bv radiat'.rs fixed under tlie floors with metal ducts to carry up the heat, finished in the walls with ventilators, is much favoured because of its cleanliness.

Probably the most modern system is that bv which air is washed and humidified and fo'ced into the bnilding bv blowers, through ducts which are finished at the wall surface with ornamental ventilators.
