Can anyone tell me about saving on energy bills by replacing an old boiler? My boiler is over 20 years old but serviced regularly and apparently in good nick. However it’s noisy and in the colder months my bills are horrendous. I do have 4dc and a big old house but even so.
I know in theory a new more efficient boiler should cut bills but before I spend out I’m hoping to hear how (or if) anyone here has saved? Thank you.
