Warmflow Agentis External Combi

[Chewbs]

I’m having issues with a new boiler. It’s a Warmflow Agentis E26 combi, external oil fired boiler. It was setup and working and I had to repair some leaks. After repairing the leaks I have bled the system and the CH won’t come on. The DHW works well, the CH works when the boiler is in test mode but doesn’t come on at the thermostat or when I manually override and put it on continuous on the boiler itself.

Any ideas or suggestions as to what I can do to fix this?

Get the installer back?

That'll be the E26C then. https://www.warmflow.co.uk/agentis-external-oil-boilers

Ok you have bled the air from the sealed, pressurised CH system.
Have you added water via the filling loop to the correct preset (cold) pressure as per how the original installer set it to replace that lost by the leak(s) and bleeding of air?

(Check the manual you should have been supplied by the installer).

1.0 bar should be shown on the pressure gauge when cold...

The DHW is unaffected by the CH sealed circulating water and is probably 'low pressure' that is preventing it firing.

It may be wise to call installer back and add extra inhibitor if significant water has been lost.
