Hot Water Cylinder Temperature

jsmithy1

What is the best/ideal temperature for a hot water cylinder? To elaborate a bit more: I have a shower pump installed under the bath and it has been playing up recently, not kicking in and needing greater flow to get it going. It doesn't sound too healthy at times, but is only two years old. Anyway a plumber came to check it out and said the hot water was too hot for the pump, which was set at 60 degrees. He quoted a large amount if I want the pump replaced (it could be worn out)! ta! JS

The HW is set at 60 or the pump is set at 60?

Cheers

The temperature gauge on the HW cylinder. There's no way to adjust the temperature on the shower pump (is a Stuart Turner Showermate 1.5 bar).

The temp in the Hot water Cylinder shouldn't be set belo 55 deg c as below this temp, bacteria can breed.

Plumber told me 60 was too hot and try nearer to 45...

Try reducing slowly and see if it fixes the fault.

45 is warm. If you can test the temperature at the tap and see if it really is 45 or if it is hotter hopefully the thermostat is faulty. The temperature of stored hot water must be over 50 degrees for a few hours per day.

I'll give it a go. Thanks

Thanks. Thats what I thoughtg you probably meant but it wasn't that clear from the way you wrote it. Stuart Turner are good pumps and the Showermate is spec'd to be WRAS compliant at 65ºC. The HWC temperature (as has already been stated) should not be less than 55 - 60ºC. The shower itself will also be probably spec'd for operation at 60ºC. So sorry but your plumber is talking out of something other than his mouth unless you have a faulty tankstat and the HW temp is much higher than 60 in which case you could possibly be damaging the pump. Are you sure that a) the flow switches are properly adjusted and b) that there is no air in the pipework?

Bin that plumber, ignore everything he told you & find another one.

Hi.

Ignore uninformed opinions. It should be set at 60 degrees.

Cylinder stat should be one third from the bottom of the cylinder, not the middle or the top third as I have seen. Strapped firmly to the cylinder wall where it will do it's job properly.

Also check the filters in the pump inlets.

If the bearings ever fail they are available as a spare.

Canucklehead is correct on all points. 60 degrees is recommended for domestic hot water as it is too hot for bacteria to thrive and it is hot enough to tackle the hardest job usually met in domestic circumstances (cleaning grease and germs from crockery and cutlery)

I concur that the filters on the pump need checking and cleaning
