Hi,
planning on replacing my WB 280rsf which is 17 years old with a Vaillant 831.
But looking on sebuk charts the 280 should be about 71% eff and the 831 about 88%.
My question is. Is it really worth me changing it just to save fuel costs? going on there predicted fuel savings, it would take 15 years to get back the cost.
Or will my boiler be running at much less than 71% due to it's age and lack of regular servicing, (i've no proof of any servicing)
thanks,
Kev.
