I have an old Ideal Elan boiler, which is around 15-20 years old. This might be a silly question I don't know, but here goes.
Is it cheaper to run on Low or High setting, Low takes longer before heat reaches required temp because less heat. High reaches temp quicker as radiators are much warmer?
My question comes from, if you drive a car 80mph you might get 40mpg, If you drive at 40mpg you might get 7ompg.
Is it the same for my boiler?
