Can someone more knowledgeable than me help me out with this one? I’m currently in the process of buying a new house which has a gas boiler and a hot water cylinder. My instinct would be to rip it all out and put a combi in as i hate the thought of using gas to heat a whole cylinder of water just to wash my hands (it has an electric shower). I do like baths though.
So would it be better for me to put a combi in or should i get solar PV on the roof and connect it to the cylinder to keep the water temp topped up? I think the costs of installing either system would be broadly similar (I’m not thinking of batteries at this point).
