Monodraught reduces cost of heating large spaces

Reductions in heating costs of up to half for large buildings and tall spaces are claimed for Monodraught’s Heat-Harvester. Installed at high level, these devices draw in accumulated hot air from above and direct it downwards. There are three models catering for ceiling heights of up to 5, 8 and 12 m. Motor powers are, respectively, 25, 35 and 75 W — so they use less than 25 p of electricity per day. The Heat-Harvester was originally developed in the USA and has been used in over 2000 installations. Because they deliver a powerful jet of air, the warm air being recirculated can be directed downwards at an angle, rather than just vertically. Only a single-point fixing is required, and Heat-Harvesters should be spaced 8 to 10 m apart. While primarily an industrial product, Heat Harvester is also available for installation in a suspended ceiling. The powerful action of the Heat-Harvester draws warm air from below the ceiling through a grille and into the ceiling void so that it can be directed down to low level.
