i have just gutted a four bedroom townhouse over threes floors - ground / first and attic.
i have therefore to decide what heating / hot system i should put back in as there is nothing right now - not even a copper pipe!! there is mains gas and electric.
it is of 1950's construction, so the walls are not very well insulated - the roof is well insulated. i am thinking of a radiator system as i am on a limited budget and underfloor heating will be too expensive.
water wise - there are three showers (1 on each floor and it is likely that at least two will require water at the same time. there is also a bath on the first floor but unlikely to be used much.
there's plenty of space to mount pretty much any system but i really don't know what's best - probably most concern is the demand for hot water - a simple combi boiler could not handle it. and i only want one electric shower as an absolute emergency.
i should say that i don't expect to live in the property for more than 5 years at the most so i do not want to pay huge amounts for a renewable energy system that takes years and years to re-coup the investment.
any advice gratefully received. thanks
