Air-to-water heat pumps
These are more intrusive as you have to connect to your "wet" system. Expect to pay £ 5,000 for installation.
You will also need underfloor heating (another £ 2,000) as these only give a water temperature of 40-50 degrees C, which is not
enough for normal radiators.
Installation cost £ 7,000.
Annual saving £ 1,000
Payback 7 years

Ground source heat pumps
With these you need to dig a large hole in the ground (100m²), so you need a big garden.
Expect to pay £ 15,000 - 20,000 for installation.
As with air-to-water systems you will also need underfloor heating.
Installation cost £ 20,000.
Annual saving £ 750
Payback 27 years

Microgeneration
You can have a wind generator installed for about £ 2,000. They give about 1 kW at 12 m/s, but it is
rarely that windy for a normal house, so expect 100-200 w, enough for a couple of light bulbs.
Installation cost £ 2,000.
Annual saving £ 20
Payback 100 years

Water based Solar heating
This involves installing 10-20 m² of panels on your roof, as well as extensive plumbing to connect them
up to your "wet" system. You will also need a new hot water tank (dual core). They work reasonably well in
the summer, but not all that well in winter.
Installation cost £ 2,000.
Annual saving 15% or £ 180
Payback 28 years
