I've just purchased a house which we are in the process of converting from two flats into a single property. The flats had two separate gas meters, although both running off a single supply from the road.
My plumber has removed one of the meters and joined the gas supplies from outside the property as this was a requirement from my mortgage company.
Originally it would have been a large Edwardian house that was converted into two flats by boxing in the stairs. As one property it will be a 5 bed house about 3000 square feet in total over three floors.
Currently there are two combi boilers, one supplying the downstairs heating, hot water and a single bathroom (we will eventually remove this bathroom). The second boiler supplies the 1st & 2nd floor heating, plus two bathrooms.
My long term plan had been to replace the whole system with a single boiler downstairs, however typically the upstairs combi boiler has just died and is not repairable, which has forced me to make a decision now.
Obviously the cheapest short term solution will be to replace the upstairs combi and keep two separate boilers.
My question is what is the downside of having two combi boilers as opposed to one large conventional boiler? Presumably it costs more to run and I guess it will be twice the servicing costs?
