Ive had a new system boiler fitted and I cannot control ch via the room thermostat. The upstairs radiators dont seem to come on . The ch doesnt come on if there is a full tank of hot water. I cannot get ch when I want it to come on. Do you think it might be the electrics. They have been back to it about 6 times and its still not working as it should.

Is the system zoned with each zone on it's own stat?
If so do other zones get heat?

No its not zoned. The radiators only come slightly warm when hw on.I cannot get ch to come on or control room temp via room thermostat as I used to before. I just used to up the room thermostat and ch would come on but it doesnt anymore
It could be that your system has air in it, bleed rads. Also may require balancing.
Are any particular areas that are cold/warm on rads. ie top/bottom?

Try turning all upstairs rads off, and see if downstairs improves.

Bearing in mind those two statements it would appear to be either wired wrongly or have a faulty part.
There's a few things it could be, but really you should get the installer back or money refunded so you can get it sorted.
But check the easy stuff first, is the programmer set to both hw and ch?
Could be your port valves or even the pump.

There are dip switches on some programmers.
Could your programmer be configured for a gravity system but the wiring is obviously not.

It was a gravity system before the boiler was changed. I have changed the interlocking on the programmer switches but do you think I may need a new programmer then., The electrician said he had taken the programmer out of the equation totally when he was checking it and that it was all ok so he was baffled
When the boiler was changed, what else was done?
