My mate has a camray 3 oil fired boiler?

hi John

you need to work out what size you need for the size of the house but as a starting oint a standard utility boiler would probably be the easiest
other types i.e system or combi which works on about 1.5 bar may cause problems on old pipework

somewhere on your old boiler it should state the btu output start with that
