Hot Water Cylinder Temperature
Comments

I have seen an advert on TV in the last week by one of the enrgy companies, pretty sure it is BG, saying 50 degrees, one of their" helpful tips".
Don't know how accurate the setting actually is on ours is around 50-55 too hot to shower in and just too hot to put your paws in for dishwashing. Haven't caught legionnaires - yet.
Agree with the comments, on the pump though, would have thought it should be capable of handling higher temperatures."If you act like an illiterate man, your learning will never stop... Being uneducated, you have no fear of the future.".....

Legionnaire bacteria's ideal temperature for multiplying is 35 to 46 °C so setting it to no lower than 50 °C is OK.grizzly1911 wrote: »I have seen an advert on TV in the last week by one of the enrgy companies, pretty sure it is BG, saying 50 degrees, one of their" helpful tips".

Not according to their website PDF page 5 .
Eliminate scalding risk by fitting thermostatic mixing valves.
From the Water Regulations Guide G18.2
'Hot water should stored at temperatures at not less than 60 deg C and distributed at a temperature of not less than 55 deg C. This water distribution temperature may not be achievable where hot water is provided by instantaneous or combination boilers'.
For combi/instantaneous DHW temperature follow manufacturer's recommendations.

Thats what you have a mixer tap for in the kitchen that also produces cold water.and just too hot to put your paws in for dishwashing.
Pump is spec'd to be WRAS compliant at 65ºC as already stated.on the pump though, would have thought it should be capable of handling higher temperatures.

Thanks, all very interesting. I had the temp turned down below 50 degrees for a day or two and has made no difference so on the basis on the above arguments have put it back up to about 58. As I said, the shower pump was only installed August 2009 and before that I had the same model for about 8 years until it gave up the ghost, so I know it's a good brand and works well in my flat. Trouble is finding someone to service it rather than a replacement: when I rang Stuart Turner they gave me the number of the guy who came previously...0

Kay. I'll ask again then. Are you sure that the flow switches are correctly adjusted and that there is no air in the pipework? Ask ST for the name of another guy?Thanks, all very interesting.

Sorry, I'm just an average Joe - I wouldn't know how to check to see if there's air in the pipes or how to adjust flow switches...0

Does your cylinder stat work?
Can you hear it 'click' at some point between turning it up to max and down to min? And/or can you hear the boiler cut out or the motorised valve shut down?

Fully appreciate that but there seems no point in warming it up too high, at a cost, just to to cool it down unnecessarily.
A bit like heating the house to 25 degrees then opening the door."If you act like an illiterate man, your learning will never stop... Being uneducated, you have no fear of the future.".....

GSR.
Yes, can hear the click and boiler cuts out when moving the cyclinder's temp gauge...0
