UVC heating element

[Pocster]

Had one of these ‘trip ‘ a few times now I.e on the actual element not CU .

What does that imply ? . Replace it ? . I assume need to drain the UVC ?

Cold showers, will do you good.

That, and some bromine in your tea.

Don’t know . Will look Monday . It’s not been adjusted since install ( over 3 yrs ago )

Looking online I see some just have a overheat cut out . Presumably therefore they are not adjustable ?

Also the price . From 40 quid to 250!

I’ll grab some photos Monday before I do anything !

Most thermostats for unvented cylinders are this type https://www.ebay.co.uk/itm/362782647811?

 

Random choice, they are available as lots of different makes and prices but all seem pretty much the same.  the thermostat plugs onto 2 lugs on the immersion element rather than the cheaper type that are separate.

 

the red knob sets the temperature.  If the overheat (button marked safety in this case) keeps popping then either it is faulty, or the main temperature dial is set too high allowing the water to get too hot, or there is another source of heat e.g a boiler that is heating it too hot.
