Protherm 40-50 Ci No Heating Or Hot Water

I was called to look at a system with a Protherm 40-50 Ci as the customers were getting no heating or hot water. When I arrived the heating and hot water were set to be on but there was nothing happening. After sliding the bottom tray off I could see an orange glow coming from the control box so I knew that the boiler was receiving power. The overheat reset button had not popped out on the front of the control box.

I asked the customer if the boiler had been behaving itself over the last week,and they said that it had been getting noisier. They described the noise as a loud whining. I opened the case and checked for power to the fan, which there was but it was not spinning. I replaced the fan and the boiler was working quietly and correctly again.

Protherm 40-50 CI Heat Exchanger

A friend of a friend has a Protherm 40-50 CI boiler which has started dripping from the heat exchanger. I was unsure whether the heat exchangers would still be available for these boilers although they are essentially a rebadged Glowworm Ultimate.

A quick Google and I find them available from Total Boiler Spares for £235.70+VAT although it says they are out of stock, it does deliver a lot of parts direct from the manufacturer. The website also gives me the part number S801382, although searching under this part number also leads to a Saunier Duval part. I telephoned Total Boiler Spares and they said the part was available in 4-6 working days direct from the manufacturer.

I also asked at my local Parts Center and was given a retail price of £550+VAT, although as an account holder I would pay a lot less than this but they did not have one in stock or available from their main warehouse.
