We are really struggling making the decision for our heating. I always come back to the same scenario – air source isn’t going to be sufficient for radiators upstairs; ground source is far more expensive and will probably require a borehole; biomass just doesn’t appeal and, above everything else, these methods haven’t been about for a huge length of time.
So, my question is, why should we not just install a much cheaper oil boiler? The house is going to be very thermally efficient so we are hoping that the heating won’t have to be on that much anyway. And, as a current oil user, we have seen the price come down and down over the past few years, rather than up and up as everybody predicted. I may be a little old fashioned but I’m taking some convincing about the new systems and although I know the RHI should eventually cover their cost, the initial outlay is huge compared to an oil boiler. BY the way, we’re not on mains gas.
