Anyone used energy saving radiator valves?

ecoterry

I am a frustrated DIYer, who would like to DIY zone my heating to give me room control, save energy and reduce my bills!

I have seen products from Pegler called i-temp and also one called eTRV. Has anyone any experience of these products?

It looks like you remove the existing TRV and simply replace, with no need for a plumber unless an old fashioned manual valve. Once on your can programme the valves like a time clock and also set temp.

There must be some budding plumbers out there who can advise me!!

Have you worked out how much it would save? It sounds as though you'd need a plumber to change the TRVs which would incur cost. You're unlikely to save significiant money on the running costs.

If you already have TRVs then it seems unlikely this would help, unless you had an enormous house and had the heating running all the time.

Fitting TRVs is a DIY job for anyone who can switch off, drain, re-fill & bleed their CH system. It's easy to figure out how to do this.
Just remember, in addition to the radiator bleed valves, there is probably one inside the boiler -should be clearly shown in the instruction manual.

With what the OP is talking about you unscrew the existing head and replace it with a new "clever" head. No draining, no plumbing, no bleeding. Wor bairn culd de it!

Hi - I've fitted 19 eTRV's in my house - it took me a total of 2 hours, including visiting a neighbour to borrow a large spanner to undo 2 TRV's that were too tight to release by hand.

I'm very impressed and can already see we're saving loads of energy. I'm now only heatig our lounge from 6pm each day, kids bedrooms are heated in the morning and from 3pm to 8pm each night, adult bedroom from 9pm to 11pm. I've turned the dining room off all together, and the play room heats from 3pm to 7pm. Other rooms are on a bit more often as we use the kitchen often until 8pm.

What I really like about the eTRV is it looks great and that it's remote controlled, so dead easy to "forward" to the next programme if we're at home early (like we have been over the Xmas break). Last night, the kids were both out on sleep overs, so we went out for dinner and to the films - using the remote, I had my eldest son running around the house and using the "sleep" button on the remote to turn off all the heating - aside from in our bedroom.

This has to save money... we spend over £900 a year on gas so that will be about £800 a year on heating (some will be used for hot water and cooking). I'd be happy to save 25% and get my money back in 4 to 5 years.

Aside from the money, the house is far more comfortable now... the old TRV's never maintained room temperatures consistently - but they were 12 years old so have probably deteriorated over time. The eTRV's do the job much better, and using the remote we can tweak the temperatures up or down easily, without having to bend down or climb over coffee tables to get to the valves.

Note for EcoTerry - I did try a Pegler type first but it wasn't that good, too noisey and lacked on design. Took it back and bought the eTRV's on line instead. They cost more but I feel it's worth it - and they're made in Britain which I prefer to Chinese equipment.

I'm sure we'll make a good saving even though we already had upstairs and downstairs heating zones, and our bills were already £600 less than some neighbours. if I hadn't already had zoning I reckon I'd get my money back in 2-years. Quicker than solar panels!

Good luck.

How much? I need to replace a TRV head anyway in a room which I only use in the evenings.

£50 each, plus £10 for the remote here;

At that price i think i will stick with the peglars until the efficacy and reliability of these is proven.

We have now bought and fitted one of the Pegler ones (cheapest seems to be Plumbclick) in our en-suite bathroom as we only use it first thing in the morning and last thing at night.

It was easy to fit and straightforward to programme.

As we are now heating one less room for a few hours, we must be saving on gas, but I think it will take a while to recoup the £23 we spent.

More flexible control in a system is good, but obviously more money saving if fitted from the start rather than as an upgrade.

There are already enough remotes to get lost in our house, without adding any more.

If you live in a house with 19 radiators then I think the amount you can save using these TRV's are the least of your worries ;o))))))
