One TRV to control 3 radiators - possible?

[FiscoKing]

Hi,

I have 3 radiators in my kitchen. I could consolidate these into one radiator for the sake of simplicity, but the radiator would be so large it would look ugly.

At the moment I have 3 trv's to adjust each time I want to alter the room temperature.

Is there a product that lets you alter the temp. of many radiators from a dial on the wall?

I am pulling the floor up in the kitchen soon, so I could re-plumb all the radiators in series, and add a single trv to one radiator, and non trv's to the rest. Would this work?

Thanks.

What you are descibing can be done but I personally would not advise it.

The best way, if possible, would be to create a seperate zone for the kitchen with a room stat and zone valve controlling it. This would involve wiring them back to the wiring centre for a proper job to be done.

Personally I would just leave the seperate trv's on each rad. Why do you need to keep changing the air temperature of the kitchen so often as to make it a pain?

I don't envisage having to change the temp all that often, but having three rads within a few feet of each other on different walls (the thin tall type) , and having to fuss over three trv's when you do want to change the temp just smacks of poor planning.

I will speak to my HE when he arrives to install the boiler and suggest a seperate zone.

Thanks.

Are you sure the kitchen has been sized correctly? seems overkill to have 3 rads so close to each other.

Have done it many times, works fine. Can be hard to balance them with the rest of the system though, because valves are quite resistive and you'll have 6 in series. Ok if you're near the pump.

If you've three rads in series you don't really need to have 6 rad valves. Just the TRV and one rad valve at the other end of the series would do. A neater solution might be to replace two or three single panel rads with one double convector rad. If you do stick with multiple rads you could leave the smaller one(s) permanently on (or off in mild weather) and just control the larger one(s) with a TRV.

You only need to learn a different technique to control the temperature.

Set two ( smaller ? ) TRVs to the minimum temperature you are likely to need, say 16 C and then just adjust the last ( largest ? ) valve's TRV to fine tune the actual temperature you want.

The whole idea of TRVs is to set and forget !!!

They have a response time of 30-50 minutes and should not be used as manual controls.

The product you might want is called CM Zone, by Honeywell. See www.cm-zone.com.

Tony has stolen my thunder here - 21 degrees is 21 degrees. Surely by definition you set the temperature that you like and leave the trv to do the job.


Mind you, people do like to fiddle.

30% of the country turn the valve to maximum all the time!

30% turn the valve to max when they are cold and to off when its hot enough.

10% ( tenants not paying the gas bill ) open the windows when its too hot!

Only about 40% ever seem to use TRvs correctly.

How many men have women who always say "turn the heater on" immediately you start a car journey with a cold engine?

Thanks, will run these ideas by my HE when he turns up.
