Electro heat Amptec 900 strange behaviour

Postby DWVW » Sun Jun 17, 2018 8:46 am

Hi All.

Hope someone can help :)

I have a Electroheat Amptec 900 electric boiler, pressurised and to a Titan cylinder.

It’s acting strange.

The boiler won’t fire up unless I ‘prime’ it with the immersion heater for say 30mins to an hour?

From cold it calls for ages then the alarm comes on. But if i use the immersion heater for an hour then fire it up it will work ?

Any ideas ??

Secondly the pump runs for about 2 hours after the boiler timer turns off. It used to run between 5 & 30 minutes ?

Are the problems connected ?

Vague I know, just hoping for some tips.
