As the subject says. Since saturday we are without heating and hot water (thank goodness its May!) A first heating engineer came, diagnosed a number of serious problems, which would add up to hundreds of pounds and recommended completely replacing as this is a very old, energy inefficient boiler (we recently moved into this house and had some idea about this from the survey). A second guy coming this morning to quote.
What should I be looking out for as this situation is a) urgent b) expensive and c) not helped by c) my cluelessness. I'm trying to learn as fast as I can but need advice.
