I have had a vailliant eco tec pro 24 fitted in my 3 bedroom semi detached house as the back boiler was condemed! Is this boiler good enough for a house of this size? I only have one bathroom with a bath, also what should the water temp and the heating temp be set to on the boilers digi readout for efficiency? p.s they have not fitted a temprature dial like the one we had in the hall for the back boiler, and have used a nearby plug socket and put a plug on the boiler instead of wiring it into the mains..... advice welcome!
