Hi.
We’ve just had some building work done and now struggling with central heating problems.
Our setup is that we have an Intergas Eco RF 24 heating the radiators (controlled by Nest) and unvented cylinder (with its own thermostat attached to the side). The hot water is favored over the radiators, so the cylinder is heated before the radiators will warm up.
Last week our Nest Heat Link was moved from being wall mounted to being put within the new kitchen cupboard and since then, we’ve not had any central heating. When the hot water is used and the cylinder cools down, it’s thermostat calls for hot water and the boiler starts working to reheat the water. However, when the Nest asks for hot water for the heating the boiler does not respond in any way.
Originally I thought that the problem was with the Nest Heat Link, but I’m not sure about that now. I’ve got the thermostat and Heat Link side by side and when the Nest asks for heat, the Heat Link clicks as if it’s switching on, but nothing happens.
If I press the button on the front of the heat link to override the central heating, the two lights (heat and water) illuminate, but again the boiler does not respond.
The Heat Link is connected to the boiler via the OpenTherm connections and the connections have been checked so there’s no loose wires.
I’m now coming to the conclusion that this may be an issue with the boiler rather than Nest, but thought I’d ask to see if anyone with some experience has any Idea of what I could try to isolate or fix the problem?
Thanks in advance, Dave.
