Warm air heating - Mike the Boilerman
The old warm air boiler is replaced with an 'air handler' or 'heat interface unit' (HIU) which delivers warm air heated by hot water from the combi. The advantages here are as follows: 1) You no longer have to find a warm-air-qualified gas bod to service and maintain the gas boiler.

3/5/2009 · Loss of around 14% can be attributed to various losses of which the dry gas loss is about 35% of the total. When both economizers and air pre-heaters are not provided the boiler efficiency drops to around 66% from 86%. When air pre-heater is not provided the boiler efficiency will be around 74 % only. Thus we can conserve about 20% extra fuel
