Damn, there goes another myth!

Plus, as I recal from a recent watchdog type programme, it's next to impossible to recoup the cost of installation, of these 'air' systems in their projected life.
A friend has recently installed a ground source heating system. By all accounts it works very well. They had to dig somewhere in the region of 500m of 2m deep by 1.5m wide trenches in the garden to accomodate the coils.
I think the thread was more about
Not messing around with wood
not cleaning ashes
Not having lots of dust/smoke
As opposed to saving money, Technopolis have installers for the inverter air con units, if they really do work at 5:1 4:1 then they sound pretty good, do not know enough about them to say

If I ever realise my own electricity supply then, I'll go all electric, but I am not paying EVN for the privilege of not having smoke and smoke stained walls.

If you look at the "best case" savings against current systems as below you see that best case is replacing electric = 10+ years, but replacing a wood burner = 20+ years.Savings annually:
Gas = £130
Electric = £610
Oil = £310
Wood = £330
Again. You have to also take into consideration the long term facts that oil, gas and electric prices are forever rising and will probably triple in the next 10 years and oil/gas will eventually run out.
Editted to add: I suppose if you are installing from new (first system) then you can take into consideration the cost of one installing of the other systems anyway which would make the GSHP system not to much more expensive.
