Help please! Santon premier unvented hot water tank (Ed.)

[Cagsey]

Hi help needed please I have a santon premier unvented hot water tank and I am struggling to find the thermostat on the tank to check that the temperature Is correct. Any help I’d much appreciated to help me locate it .. thanks

Red dials on the immersion elements

 

[Cagsey]

I don’t have those dials I have a box on the front and this is what’s inside

Is there a dial here?

 

[Cagsey]

No dial

 

[Cagsey]

That part is labelled 1-5

Sorry then I'm out of ideas, I thought there was a device below the arrow that could be adjusted with a screwdriver.

EDIT
Found a photo

Yes that’s what it looks like but I don’t know what I would do or turn it as it’s just a screw there… no arrow or anything. My water tank is in my airing cupboard and it doesn’t seem to get warm like it used to. So wondered if the temp was correct on it. Thanks

The slot in the screw should align with the numbers, so that if it's turned fully anticlockwise with a small screwdriver it will line up with 1 and if turned fully clockwise will line up with 5.

The adjustment is provided for you to adjust the hot water temperature to your personal requirement. Above 60C is recommended to prevent legionella. But what that corresponds to on a scale of 1 to 5, I don't know. The correct way to check is by using a thermometer and measuring the water temperature at the taps.

That’s great thanks so much for your help much appreciated… would that make my airing cupboard warmer if the thermostat was higher? I will check when I get home

 

[Cagsey]

If I take a pic later and show you what it’s like would you be able to tell me what number it is currently on? Thanks

It shouldn't make any noticeable difference to the temperature in the airing cupboard. The insulation on the hot water cylinder is designed to keep the heat in and the water hot, and not let it escape to the airing cupboard.

Ok thank you

 

[Cagsey]

Here is what it looks like.. what would that be on please

Is that on 4?
