Can this be fixed? (Grant oil boiler)

[Best]

Tempting fate, but one year on and all is good.

Thanks for keeping an update. You could be lucky as some leaking oil boilers were just down to a poor weld. If oil remains at this low price it won't save a lot in actual savings, but maybe you should consider getting a Grant Vortex condensing oil boiler in the better weather if you plan to remain at the property

Always fit an auto bypass valve so you do not get too high a temperature differential between flow and return
