    I will be installing several smoke - heat and carbon monoxide detectors shortly as per spec. I've not done carbon monoxide detectors before.

    Heat Pumps - Feeling my way

    Just back from a Logic Certification Heat Pump course. Quite informative. Whilst I really like the concept of ground source, its complexity and cost started to do my head in.
