The "FREE* £5000 boiler grant" has stirred up lots of attention
Unless your house is very well insulated and has wet under floor heating ,heat recovery ventilation etc (in which case your heating bills are probably quite low anyway ) then you will need to add/spend 10 grand plus of your not "FREE" own money and have your house raped by tradesmen to make the house suitable for air source heat pump .
the national grid is antiquated ,it can't cope long term with increasing power demands without massive investment .
the massive investment will come from increased costs for electricity to the end user ,as demand increases, so will cost (like gas now )
I don't sound very "on board" with the saving the planet from global warming do I ?
If you want to make a difference to energy bills look at your appliance ratings etc ,turn the heating down
something as simple as swapping from a big plasma TV (some use 400+ watts
) to a modern LED one (sub 100 watts) can actually pay for the
new toy energy efficient alternative appliance in a short time .
100w old incandescent light bulb/lamp costs £1,20 to run for 3 days constant (2.4 KWH ), buy a 5w LED lamp/bulb for a quid, 3 days constant running (360w) is 6 pence , you've paid back your investment ,any usage after that is a big ongoing saving
most people have swapped to LED lamps already but there are still loads of people with halogen downlights and ye olde fluorescent lamps .
I can see a lot of poorly installed ,costly ,inefficient air source heat pumps being installed with the lure of "FREE* MONEY"
* not free at all
