Pressure too high on boiler

[Debby]

Hi I have a heatline vizo 24 boiler (which I know is the cheapest boiler around !) it is 11 years old and the pressure is constantly rising. We bleed the radiators to bring the pressure down but at the moment the pressure is rising even though the boiler is switched off due to awaiting a replacement fan. Any ideas what could be causing this and what could resolve the problem ( I know a new boiler would sort the problem !)

Yes but you need to be gas safe to be able to repair a boiler sorry to say

Disconnect the filling loop

Could be your plate heat exchanger has been breached.

Make sure your filling loop is closed properly and this has nothing to do with a fan.

Filling loop left on or plate heat exchanger passing, not a good boiler to work on , I think you will see your engineer on a regular basis with this boiler unless it’s spotless on a regular service. Hope this helps
