Thermostat and trv radiator in same room = inefficient?

thor

My central heating system has a wireless thermostat installed in my living room which also has a radiator with no trv. I realise that this is done to ensure that the at least one radiator will allow water to return to the boiler but it means that I lose flexibility when it comes to heating other rooms.
For example, once the living room is up to the required temperature, the boiler switches off and I am unable to heat my bedroom or bathroom which may be much colder.
This seems to be very inefficient as you would always need the living room to be heated(even if there is nobody there) if you want to warm up other rooms.
Is there a way around this?

You should still have a valve on the radiator in the living room. If you reduce the flow it should take a bit longer to heat up and help balance with the rest of the house. Youll probably have toplay around a bit to see what works. Ensure you dont close it fully.

Get programmable TVR/thermostats for all rooms.

Get a TVR for the living room and move the thermostat to a cooler spot like the hall.


we keep all rooms cooler than the living room anyway as we use that most of the time, in the evening open the living room door to let the heat upstairs.

A TRV is a thermostat and will therefore work against the room thermostat. It doesn't make sense to have both in the same room. Additionally, the TRV only controls flow to the radiator, it doesn't control your boiler. If all of the TRVs in the house shut down, the boiler will be firing for no reason. Assuming it has a bypass, otherwise it will overheat and shut down.

If rooms are not heating up evenly, then you should first of all balance the entire system so that all of the radiators heat up equally. Then it's a question of if the radiators are sized correctly for each room.

As suggested above, put the wireless thermostat in the hall and ensure the radiator does not have a TRV. Set the temperature sufficiently high so all of the rooms heat up adequately.

The alternative is to fit a system like EvoHome so that each radiator has it's own wireless thermostat which can control the boiler. Expensive, though.
