warm air heating
Aug 13^th, 2005, 8:35pm

Can any1 give advise on warm air heating in a bungalow.
I know there are purpose made systems that consist of a free standing module that has to be placed somewhere within the occupied area, but they take up a lot of space and seem to be only affordable by lottery winners!
I'm thinking along the lines of a commercial heating only fan coil unit/units installed in the loft with a heating coil supplied by a standard central heating gas boiler.
I realise there would be problems providing adequate insulation to the fancoil units.
Any advice much appreciated - Thanks

If you insist on going down the environmentally unfriendly way then consider air con units that fit into the ceiling.

I doubt the a warm air boiler is any more powerful than a wet boiler so in theory it will take roughly the same amount of time to heat the whole house (if you ignore the few mins it takes for a radaitor system to warm up first).

Various web sites will tell you that warm air heating is bad for those with Asthma. I'm going with UFH throughout for my new house because I also dislike radiators.

Think you're find that warm air is more expensive to run as there's no surface temperature to hold the heat.

Its the fine layer of dust that settles over the house that Asthma suffers love to hate, in fact it's a very unhealthy atmosphere all round, spreading bugs and germs at ramdom.

The system installed in the 60's and 70's were direct gas fired heat to air and were poorly designed, poorly constructed and very inefficient.

Perhaps you know I've been in the industrial game for 45 + years Sparxxxxx.

You're comment about modern units are of course correct, and they have effective filters to prevent the spread of most bugs and germs.

The biggest single factor in the spread of legionelle is Lips Sealed

the filters should be changed every 6 months, something that dosen't happen in real life.

It needs moisture and is most commoly found in cooling tower ponds due to a poor water treatment regime. I've only been in the building services industry for 39 years, but have a very wide experience in many different areas of industry.

Areas of particular concern are:

* Water systems involving a cooling tower or evaporative condenser

* Air-conditioning systems, especially those incorporating humidifiers or air-washers

* Hot and cold water systems

* Spa baths, jacuzzis and other pools in which water is agitated and re-circulated

* Other systems where water is stored between the temperatures of 20-45°C and which produce an aerosol or spray
