I have three options to expand our central heating and hot water… I dont have enough info to base an opinion on…
Basically, our terrace house and all services were split in 1953, The lady downstairs, who we looked after for 10 years, sadly died. We are now the owners of her half of the property and intend to rejoin to make 1 house again.
Upstairs has a combi rated 28kw, it does our 7 rads, shower and hot water just fine. Downstairs has nothing except the coal fire and the old electric immersion heater (now gone). Downstairs will have 7 rads and a shower added.
Options are:
New 42kw Combi condensing boiler to do the lot
Additional smaller boiler to just look after downstairs rads/shower/hot water
New boiler and unvented tank for the whole lot.
Given the limited info here, whats the best bet?
Thanks
