See attached link for solar / ASHP (i.e. 14kw ecodan) calculator - need to up our radiator size anyway

I like the idea of this as I become a lot less dependent on energy companies (and the inevitable ensuing inflation)

I would have liked a larger Solar PV system but don't have the roof space (two tiered roof).

ASHP RHI tarriff scheme is not confirmed yet - hence you need to change the figure in the formula in year 1 to what you think it will be and then copy the fomula down... anyone know when to expect this to be confirmed?
Im generally being told for my house (1990s 4 bed detached) it will be £1500 + some savings on current bill (crappy old gas combi)

If the figures end up being anything like this then it means I can be mortgage free in c12+ years (when ill be 42)

I thought about using a shade greener for the solar, but havent convinced myself yet that there wont be future problems when we want to sell house & move.

Lastly im told 14kw will be enough for our house.. our combi is 27kw.. judging by our bills we dont use a great deal of gas.

Any comments? - I know cardew / noncom will have some good pointers

p.s. i know I need to factor in a new inverter (£1k) and a bit of maintenance but dont see this as being too much in comparison to what we are already paying for gas / boiler inspections.

When I paste the link it says "Windows cannot find...." so I cant see your calculation. With regard to when the RHI details will be confirmed, the results of the Govt's Public Spending Review will be published on 20 October so perhaps not until then.
