Air Sourced Heat Pump.

Zoomup
A person today that I was talking to, that has had a new build home which was required by building regs. to have an air sourced heat pump for heating and hot water, complained that the system was slow to heat or cool as required. He said that he had to have underfloor heating installed. It was slow to warm the rooms on cold days. He recently had the system set to cool the rooms on the very hot recent days. But this morning was cooler and he required heating. Is this normal?

    If you're designing a building from scratch, why not use warm air heating ducts?  Saves all the plumbing, and the system can run at a lower temperature.


    I owned a house once that had warm air heating It was built in the70s and had a gas "boiler". Hot water was stored in a conventional vented copper cylinder. A fan blew the warm air around the house. The system was very fast in raising room temperatures if you came in from the cold in the winter chilled through. The only real minor drawbacks were:

    1. The system was very good at blowing dust about the house.


    2. It was slightly noisy in operation due to the fan and moving air.


    Its good points were its efficiency and speed of operation. The boiler could also be controlled by an old fashioned time switch built into the from of the boiler casing for automatic control.
