How to Utilise Roofspace Heat
If there is useful roofspace heat a thermostat causes damper to move so that warm air in roofspace INDIRECTLY heats the incoming fresh air, which pressurises home living space. Exhaust from the home is then “passive pressure exhaust”. Another option is to “partially” open the damper so exhaust is from both roofspace & home. Avon Copyright 1996 |
