Hi All, A really interesting thread a lot of which I think relates quite closely to my situation I'd be really keen to hear how @Spoogster has got on with the Ovo scheme installers, as as I say in my copies initial post below they didn't seem keen at all on our property as we have microbore plumbing throughout. I've had some quotes and have got hold of the Freedom Heat pumps calculator and have had a play around with that. We're thinking of replacing a 20yo Gas boiler which obviously makes the cost/benefit calculation quite tight. It's existing microbore and we've had one suggestion of using a low loss header to help with the issue and another of using a heat exchanger so keeping the Radiator system and heat pump system totally separate, however the Ovo energy government trial being organised by Retrofit works in London dont want to use us unless we consider having all the microbore replaced with larger diameter pipework, as they say Daikin and Mitsubishi who are supplying the trial dont have any solutions to avoid potential noise and cold spots that they think the microbore may cause. Sorry for the lengthy post but I'm getting pretty confused at the mixed messages! ? Any guidance from the wise heads on here welcome. Thanks

Awesome, I shall post my lengthy rantings there and see if there's any useful advice forthcoming. Thanks

Hi Both, @SteamyTea I've had some quotes and have got hold of the Freedom Heat pumps calculator and have had a play around with that.

Hi, this is my introduction post. I'm mainly interested in the ins and outs or ASHPs especially with regards to their suitability with Microbore plumbing. All advice and guidance welcome. Cheers!!!
