That boiler looks old, are you sure that it might not be better long term to consider a smaller, more efficient unit

Aye, well, there's the rub. We're not thinking long term. Assuming that Jen and I haven't killed each other after this trial living together thing, we'll be looking to get a 3 bedroom (one for us, one for guests and one for PCs) place. That'll be in about 6 months or so.

We're just replacing the crappy kitchen that the council fitted back in the 60s with something a bit more modern looking, in the hope that we can increase the value of the flat accordingly.

Dropping a (thick) wedge of cash on a new boiler isn't in the plan.
