Discuss How do I turn heating on and off using thermostat in the USA area at PlumbersForums.net

Hi there,

We recently had work done on our flat and the plumbers moved the combi-boiler to a new location and installed a few new radiators. The boiler is wired back to a new heatmiser Neo-stat thermostat. Now that it is starting to get cooler I thought I would test out the heating. So I turned the knob on the boiler from the hot water to the hot water and radiators function.
I then turned on the thermostat and set the temperature to a nice 25 degrees to get the radiators to turn on. Nothing happened - no heat. I played around with the thermostat for a while but nothing would make the radiators turn on. I gave up and turned the thermostat off. Then almost instantly all the radiators fired up and got hot! I then turned the thermostat back on and the radiators stayed on. I then turned the thermostat off and the radiators remained on.

What could be going on here and how do I get the thermostat to turn the radiators on and off? Only way I can get them off is to turn them off at the boiler.

Any help would be great!

Hi. I hope some one can help. I have a condensing oil burner and it runs fine but the radiators don't heat. Heats the hot water fine. The pump runs and the thermostat turns the boiler on and off. Thinking it could be a thermistor. All help greatly appreciated.
