I have a Boulter Boilers Camray 15/21 wall mounted external oil fired boiler that was installed in January 1995, replacing a Parkray solid fuel back boiler.
The boiler has been serviced annually since new.
I believe I am right in saying that the boiler Output is 19KW/65000 BTU/h.
According to the info on the boiler scrappage site it has a SAP seasonal efficiency of 70%, and the SEDBUK rating band is F
I have a 2700 litre(600 gallon) Balmoral tank.
With the rising cost of heating oil I am wondering whether it would be prudent to replace the boiler. In the past when I have spoken to the engineer who services it he has always said "if it ain't broke don't mend it", only replace it when it packs up. That has always been my motto but now I am not so sure as I can't see the price of oil changing much except upwards.
At the time the boiler was installed the installation certificate states the following:
Pressure: 110 PSI
CO2: 11.5%
I would be grateful if anyone could give me any advice on what sort of savings I could expect (how much less oil used yearly for example).if I changed to an A rated boiler and what things I need to consider when looking at a replacement.
The boiler runs 8 radiators of various sizes and 2 towel rails beside heating our hot water.
Incidentally, can I ask 2 supplementary questions:
a) Is there an easy way to calculate the BTU of a towel rail?
b) Is it more energy efficient to heat the hot water with an immersion heater in the summer. I have read somewhere that the boiler efficiency drops significantly in the summer because before the water in the cylinder gets heated the flame has to heat the inside of the boiler, the heat exchanger and all the water in the pipes leading to the hot water tank.
Many thanks
