Boiler shutting down - could it be Danfoss Actuators for underfloor heating?

[andyfreeman2007]

Hi

I had this problem before and British Gas fixed it, but Im not sure what they did, so Im trying to save on calling them out. The main boiler is turning itself off and needs resetting to restart. In the meantime the main waterpump keeps constantly running. I think last time the guy changed one of the Danfoss Actuators on my underfloor heating and that solved the problem. Does this make sense/any suggestions?

Thanks so much!

You don't say what the boiler is.

Does it have a temperature display and can you watch it while it heats up and trips?

I'm assuming it's overheating, in which case you could be right about a dodgy actuator causing poor circulation. How many actuators and zones are there?
