Heating in flat issue

[travispekka]

I live in a 2 bedroom flat. The kitchen and lounge are one room. I have a combination boiler for water and central heating. There are standard radiators in all rooms that have TRVs except the lounge/kitchen area, this has 2 smaller radiators with no TRV. The thermostat is on the wall in the lounge.


So the problem i have is that the lounge achieves ambient temperature fairly easily, especially if the cooker is on etc. So because of this (excuse my naivety) the thermostat records the temperature fairly fast. The side effect is that the rest of the flat doesn’t warm up, because the radiators globally are on only briefly. If i turn up the temperature on the thermostat so the radiators elsewhere are on for longer, the lounge is roasting. So either the bedrooms are cold and the lounge ok or the bedroom are ok and the lounge is too hot (and/or wasting heat)


What can be done to bring some equilibrium to the heating in my place?


Would putting TRVs on the two radiators in the lounge change the dynamic? At the moment the TRVs in the other rooms are set to ‘5’ the max (is that correct?). Would adding a TRV in the lounge allow me to set it to low hence reducing the temperature in the lounge keeping the heating on all round longer. Or am i confused?


Or should i replace the thermosat with a portable one and just take it where i want to be (if that’s how they work) but that will still over heat the lounge when i'm not in it, so not really solving that issue.


Im assuming splitting the heating up into sections would be expensive and possibly not practical in a flat.


Any help or thoughts and suggestions very much appreciated. Thanks in advance for any expertise.


What i have at present
-Honeywell CM67 wall mounted thermostat
-Isar HE30 combi
-Normal radiators with Mistral controls in bedrooms. No controls in lounge.

Try covering up the thermostat in the lounge with a temporary box sealed with tape. I expect that will prove the thermo is wrongly sited and giving false info. But yes trvs on the lounge rads will be a good idea and maybe re balence the system ...chking

You could try turning one of the lounge rads off to see if that makes a difference

The easiest option is to relocate the stat. The TRV head would need to be removed whilst testing. When the ideal room (coolest) is decided on, you'll need some work doing on valves.

There is never the perfect place for a room thermostat especially in a small property but having a mobile stat will allow you to find the best option for the way you live your life, as said above when you find the best option you will need to get the valves altered to suit the new layout.

Thanks.

I guess my biggest issue is that the kitchen and lounge are as one. So theres never going to be an ideal place for the roomstat, because if i put it in the coolest room, ill still have the issue i described originally.

Ideally the lounge need to be independent from the rest of the flat.

I will get some TRV on the lounge radiators and possibly a portable roomstat.

Why do the valves need altering?

Many thanks

As Shaun suggested before you do anything just trim down or close the rad in the lounge. It may take a little tweaking but that way the rest of the flat will get up to temp before the lounge stat cuts in.

You would not normally have thermostatic valves where the wall thermostat is positioned you either have one or the other as they could work against each other . Kop

I would remove the TRV in the lounge/kitchen then adjust the lock shield on the radiator to reduce the flow, thus slowing down the time it takes to heat up. This in turn will give the other radiators time to heat up fully before the thermostat turns everything off. It will be trial and error, but I would start maybe nearly closed then open it slowly until you are happy with the heat balance across the flat.

A bit like balancing the system without the trvs messing things up

There aren't any TRV's in the lounge/kitchen !!!!

Let us all know how you get on please ...centralheatking
