Thanks everyone for your help.
Ok here's what my feelings our.
More than anything I would like to completely get rid of LPG, it's only going up in cost (just out of control on 47kg cylinders) and I hate the site and idea of it. We also desperately want to get rid of the boiler in our kitchen - that would be a huge bonus for us.
We don't want a halfway house. The idea of still keeping the boiler as a backup (although makes it cheaper to run) just doesnt satisfy me. If I'm tackling this issue, I want LPG gone.
We have space upstairs for a themral store, so buffer or hot water tank is not an issue.
I understand that needing to oversize rads, having a solid wall house and microbore piping is not an ideal setup and we wont achieve the COP stated by the manufacturers, but these are things we can slowly upgrade in the future to improve the COP.
To oversize rads only means buying 2-3 rads and swapping the smaller rads with the ones we're taking out. So wil cost about £600-800 to upgrade.
Something I hadnt mentioned is that we have a 2kw PV array covering the whole roof, which would go a little way to supplementing the elec consumption. But does rule out solar hot water option.
Am I crazy for still wanting an ASHP?
I'm happy to out-lay money now to safe guard for the future.
Or should i be looking at a gasifcation wood boiler (we live next a forest and have space) / biomass boiler or maybe ASHP air to air?
