Smart Radiator Thermostat Valve Buyer’s Guide

Ease of installation

Smart radiator thermostat valves are designed to fit most radiators but look out for products which come with adapters as part of the kit.

Installation is usually straightforward. If access is tight, choose a make which fits both horizontally and vertically.

Power is supplied with two AA batteries so there is no need to wire in a separate power source or drain down your system before you fit the valve.

Be aware that some thermostat valves don’t work with gravity-fed heating systems.

Control and Features

It is helpful to work out what you want from Smart radiator valves before you buy, are you looking for an entire integrated home heating system or do you just want to add a Smart valve in one or two rooms?

Some valves are only designed to be used with a like starter kit so check the specification carefully if your plan is only to use one or two thermostat valves around the house rather than install an entire system.

Almost all valves offer control via an App, and some integrate with voice control systems like Google Assistant and Alexa.

If tech baffles you then most radiator thermostat valves are designed to be operated and programmed manually. Some valves come pre-set for ease of use or you can devise your own schedules to suit the house routine.

Look out for features may be crucial to your usage such as Open Window Detection which turns down the heat if a window is opened or child protection to prevent tampering.

Energy Savings

Just altering the temperature to suit different rooms and the daily schedule will save a lot of money on energy bills regardless of which product you use but some systems do claim to save more than others.

Most savings come from the sensitivity of the system’s response and the sophistication of the user, but you should expect to see reductions in your bills of around 30% with some products claiming they can cut your energy bills in half.
