Benefit of having Wireless Thermostat

Jag1978

Rad balancing? Never heard of that before, Wouldn’t say completely cold at the bottom it is hot but not as hot as the top.. I guess it’s worth looking into… As the system is over 5 years old now I don’t think I’ve got much chance of getting the installers to correct it… I have a British Gas Homecare 400 agreement would sludge removal and balancing be covered as part of this??

Looks like I’m going to have to get a Wireless Room state which I’m sure will benefit me short term and long term with the bills

British gas will not do it or balance the system. They will offer you a powerflush for about £700. The chances are though you will not need this as correct balancing of the system will proberly cure it from what you have descibed.

Do you really think a wireless thermostat will save money? Or just be more convenient? Frankly we so rarely touch the controls on our wired thermostat I don't see it as being very useful or "money-saving".

FWIW- changing functional windows very rarely results in a financial saving either. Best of luck!

Your probably right about the money saving element... maybe just having a standard room stat rather than a wireless one will make more sense...

As for changing the windows well I think it will become necessary very soon as the job was very poorly done.

You say cold at the bottom hot at the top, this sounds more like air in the system, bleed this radiator, even though not much air coming out at first, keep an eye on the water pressure when bleeding mine is set at one bar, the system will not start below a certain pressure. Very unlikely to have that much sludge in a newish system assuming the system was powered flushed when the new boiler was installed. I would also say get a wireless thermostat fitted, you have more control over the heating.

Already gone through a bleeding process.. I always thought that if it was hot at the bottom and coldish at the top then bleeding is requried... never the less it's already been done... As previously said it may not be sludge but a balancing issues!

There have been some mixed responses for having a wireless stat. Eitherway I need some kind of stat so I'll see what a heating engineer will advise and go from there.

Sorry, I don't agree about the rad needing bleeding. If it is hot at the top then there is no air in that rad. The problem is more likely to be sludge in the rad and not a balancing problem (cannot be ruled out though!). If the system did not have any corrosion inhibitor put in then there could be all sorts of problems with sludge and limescale etc.

You definitely need a room stat - that's for sure! Looks like the jury is still out for having a wireless one. Another thing to note is that just because the a stat maybe 'wireless' it doesn't automatically mean that it is designed to be moved from room to room. Some wireless stats just give ease of installation as you don't have to run a cable from the stat to the boiler and are designed to be permanently mounted on a wall, usually in a hallway.

Question. Is it a combi boiler or sealed system boiler. or open vented?
When systems are sludged, The rads are cold at the bottom. The easy way to find out is drain a rad into a bucket and look at the water. If its Thick and black its sludge.
If it was a new sealed sytem when installed, boiler and rads then i would say its a balancing issue.

It's a Vaillant Turbomax Plus 824e which I believe is a combi boiler... From the looks of it looks like I need to check for sludge first then carry out a balancing procedure on that particular rad!

Suppose the idea about wireless stat makes sense if wiring in is not possible. I'm thinking of going for Valliants own one VRT300f which is compatible with my boiler... Either that or a honeywell equivalent.
