Radiators upstairs are on downstairs aren't

[bettz1]

Is the pump spinning ,is its body exceptionally hot ?

Yes the pumps quite hot

It's on number 3 I did switch it to 2 and then back

Time to call in a plumber ,your pump may not be circulating water.

We've messaged one

We've got him coming Tuesday

He did send this

If you want to try more yourselves.

Close all the lockshields then open them all just half a turn

Turn on heating and go around the radiators. If they are getting hot leave them at half a turn open. If they are cold open an extra half turn. Wait 5 minutes check again.

Keep repeating this process only opening cold ones by half a turn each time and leaving the hot ones alone

I wouldn’t go as far as a half turn, I did mine on an 1/8th turn first and then turned each lockshield another 1/8th turn until all rads got hot.

Which radiator did you start with closest or furthest?

I think people buy mechanical TRV's because they don't need an app, dont need batteries, rarely go wrong and are generally cheaper for a good quality TRV rather than pay cheap for a poor quality electronic TRV. I dont see the point of a "smart" TRV that cant control the heat source, you may as well have a reliable mechanical TRV with less hassle.

My eQ-3 TRV heads do not NEED an app, since the Bluetooth version they can use an app if you want, but can be set manually. As to not controlling the boiler, in the main they stop a room being heated when there is no one in the room, so don't need to connect to the boiler, in the room where it does need to fire the boiler (wife's bedroom) it is connected to the boiler.

The same argument with a wall thermostat, why have a wall thermostat which has one set temperature if you can have one which adjusts temperature depending on time of day.

It all started with the removal of the tungsten light bulb, at night the inferred from the bulb made one feel warmer in the evening, even if the air temperature stayed the same. When the tungsten bulb was removed from sale, we needed to raise air temperature in the evening, so we needed the programmable thermostat.

From your first paragraph it looks like you agree with me. If you use the “smart” TRV’s manually then why not just use mechanical TRV’s and save on batteries.

It looks fully open.

My plan was to get the nearest and furthest away hot then slowly turn the others 1/4 and extra so on.

I've fully opened it but still no heat, the pipe doesn't feel as hot now.

You can’t tell if a valve has stuck by looking at it, it will stick internally with no visible sign, repeated tapping of the valve body can sometimes free it .

I could press it down and it looks like the ones which are hot.

I'm having another go this time just the downstairs living room radiator and kitchen both are heating up atm, ‍all the others are turned off.

 

[bettz1]

So the kitchen and living room are now red hot ive just 1/4 turned the hallway and downstairs bathroom and there heating up

If it’s jammed shut the pin can still move freely .

Success there all on again.

I did give the pump a few taps of encouragement.

Will test it again tonight

Thank you for all the help & advice

You can get wall thermostats that allow programming of several different temps for different times of the day. You don't need programmable TRVs to achieve this.

The TRV stops the room overheating, we can set the mechanical TRV between 2 and 3 on the dial, which will stop the radiators heating the room to over 18 - 22°C, but that setting remains throughout the day, 24/7, what we want is for day rooms to be heated in the day and night rooms heated at night.

We can select sample rooms, a bedroom against a north wall, and a room downstairs, with no external doors, and no alternative heating again against a north wall and put two thermostats in parallel to turn on the boiler. But if the boiler is running, all rooms will heat up, so we want to have some time device which will select when rooms are heated.

The control on the electronic TRV allows this the temperature can vary by the hour or the day, all set with the two buttons and the button dial, so rooms are not as warm when not in use, we want the room to be heated, so it can recover quickly, but not as warm when not in use. I will admit easier to set with the phone, but it does not need the phone, it can be set without it. The problem is, unless the boiler is running, the valve will not cause the radiator to heat up. Setting the wall thermostat to heat and cool in stages can help, or fitting multi-thermostats in parallel. The latter is what Wiser allows.

You can get wall thermostats that allow programming of several different temps for different times of the day. You don't need programmable TRVs to achieve this.

This is how we get the boiler to fire, but basic the TRV stops the room overheating and the wall thermostat stops it getting too cool. So both need to be programmable. No point in only one.
