Advice needed - we need to replace the boiler in our 1920s (not v well insulated) semi.
All plumbers we've spoken to say we replace with gas at this stage and from a pure usability perspective we probably want an invented cylinder.
I don't think we have money to insulate the whole house well enough to go heat pump at this stage, but I don't want to shell out a tonne and make it more difficult to do that in the future - if we go with the plumbers recco and put an unvented cylinder in the loft, is this going to make it a massive pain to sub in a heat pump later? I guess yes, but what is the alternative if the building is too leaky for a heat pump to really work at the moment?
You need an unvented cylinder for hot water with a HP so you’re not wasting any money getting one now. Just make sure it’s big enough to store water at 45 degrees and meet your household needs.
