I've got a problem with an oil boiler overheating the water, I have a solution and if anybody has any relevant advice, I'd be obliged.
I have a Firebird 90S oil boiler, which was installed about 10yrs ago. It has a Cordice 542788 thermostat fitted, which has a range of 60-90c apparently. The water temperature tops out at 68c when the thermostat is on its lowest setting so either it is not working properly or there is too much leeway in the manufacturers settings.
The problem is that the hot water has damaged the shower pump. The easiest fix being a new thermostat which actually works and a better range.
I have found this on eBay which looks like it might do the job:
I've then had a look at the manufactures and found that the only one that they supply is for a hot water cylinder, although it looks like you can buy copper pockets for it, which I understand to be sensors on wires rather than a ridged spike that goes into the cylinder.
I have contacted Firebird who are of the opinion that the wiring is compatible, I'm just awaiting a reply from the eBay supplier to confirm the length and diameter of the pockets to ensure that they will fit into the boiler.
The industry standard for boilers appears to be 60c< and the for shower pumps its 60c> so there is a very fine line of tolerance. I do understand that stored water should be around 60c to prevent Andy bacteria forming. I'm guessing that Thermostats are juts not very accurate, so having a wider range of operation is surely an advantage to overcome this.
Many thanks in advance,
Steve
