About this deal

If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag.

SCAMMER WARNING: Due to a spate of recent scam attempts (some successful) recently, if you're doing a deal in the classifieds, ONLY USE PAYPAL GOODS AND SERVICES UNLESS YOU KNOW THAT INDIVIDUAL PERSONALLY. With smart radiator valves, you can enjoy all the benefits of thermostatic radiator valves, but with even more functionality. As a result and given that you are not supplying direct, its somewhat doubtful that Id use your services again.I have 3 or 4 radiators in my house for which tado don't provide the adaptor, and they're not possible to source elsewhere.

Complete your Smart Thermostat with Additional Smart Radiator Valves and take control of all your individual radiators.

A thermostatic radiator valve is that little thing on the side of your radiator, and if you’ve ever wondered what a TRV is and how it works, then rest assured that it’s pretty simple.

The commissioning guide for the TRV4 valve seems to refer to the EB and there's no such document on the EB page. Browse our full selection of radiator valves and discover the perfect product for your home heating today.

Personally I have never succeeded in balancing radiators using the temperature drop method - because it is just not stable. Having had a leaking valve every other month this year (eighteen years from build), I'll be swapping every valve shortly (we have a kitchen refurb booked where the esystem will be drained anyway). UK habit of turning on heating for short bursts "full blast" rather than longer time at lower temperatures. Thermostat received today, followed instructions, linked to existing receiver as the stated it would, central heating now working perfectly and temperature controlled via new thermostat. To avoid damage to the valves and the heating system components, and the formation of scale deposit in the hot water heating system, the system should be flushed and a proprietary inhibitor needed.

This Round Corner Thermostatic Radiator Valve and Lockshield Chrome Valves offers control over your radiator so you can heat your room in comfort.Going back to the Drayton valve-bodies, I'm surprised to see olde-worlde instructions to set them for an 11°C drop. As the room cools, the Drayton thermostatic radiator valves open to allow more hot water through and maintain a constant temperature. Drayton's TRV4s set the standards for design, performance and quality, and are now A-Rating for energy efficiency. And as the room temperature changes, the valve head expands, adjusting a pin in the valve body so that it opens or closes. These locations include / but are not restricted to UK Highlands and Islands, UK Non Mainland, Isle of Wight and Northern Ireland.
