Eco electric hot water boilers

[rocketmanbkk]

Friends

These boilers, big & square.

Any advice on them?

For instance, they usually have a stop tap above to isolate cold going in BUT not a valve to isolate hot coming out.

I thought once the cold was off the hot would stop. No, keeps running.

Any thoughts?

Off to kip now.

Enjoy your extra hour!

How long did you run it for? They can run a bit longer than you would expect

 

[rocketmanbkk]

I ran it for about 2 mins.

 

[SimonG]

Ah well not that then.

No way its the cold bypassing back through a dodgy mixer, shower or non return valve?

 

[rocketmanbkk]

Mmm.. There were no other valves anywhere in the flat. Mmmm...

Isn't it just a thermal store with a coil?
