Having a thermostat radiator valve connected with the heating system of your house is always a good plan. It not only helps you regulate the temperature of your home, but the device also saves energy by monitoring the amount of water that flows in and out of the heating system.
A thermostat valve is not a “one size fit all” kind of thing. It comes in different types for different needs. Straight, corner, and angled are a few of the conventional types of valves. Also, some brands have started introducing smart thermostats, which you can control via a companion app on your smartphone or tablet.
We have reviewed the best thermostatic valve and nine other suitable products from reliable brands available in the UK, so you do not have to do the work. This should give you a great idea of the different products available so that you can pick one suitable for your home heating system.
