We are looking to replace an old Baxi gas back boiler - which is absolutely reliable but probably quite inefficient - with a multi-fuel boiler stove and a conventional condensing system boiler and possibly, in the next year or two, solar thermal. By this time next week we should have 3.3Kw solar p.v. installed also.
I have been reading everything I can on the subject and have a pretty good understanding. I had more or less decided that the thermal store was the answer. However, after talking for quite a long time on site with a very experienced plumber/engineer yesterday, who initially agreed the TS was the way to go (he has fitted a few but mostly small commercial properties), we wondered whether a Dunsley neutraliser might be a better bet. (I had originally thought this was the answer until I discovered thermal stores!) The reasoning was that keeping 300 litres of water at 80 deg. takes some doing.
The house is occupied all day every day, more or less. It is a three bed bungalow with a part completed loft conversion (pending a decision on the heating!). 9 radiators and 1 bathroom. We have mains gas but the intention is to reduce the gas bills. We are also considering a 1.5Kw immersion for water heating when the sun is shining.
One last thought - if we did go down the Dunsley route, could the vented tank include a solar coil?
Any thoughts would be appreciated.
Many thanks.
