Customer’s Verdict

Majority of the customers prefer easy installation and modern technology being featured in the thermostats, which was one of the indexes while choosing the best five of the lot while compiling radiator thermostats. 

Drayton Wiser is greatly applauded by the customers for its delicate design, easy access, great compatibility and connectivity range. The only thing that you should be careful about when buying a Drayton is for a gravity-fed system, for which it is not suitable. 

Tado° on the other hand has evenly good features and amazing feedback from the users. The compatibility and connectivity are best as far as the above-mentioned products of tado are reviewed. Works very well with mobile app and auto-assists. You may feel a bit worried about the auto-assists subscription and fee but even if you don’t pay for that feature, they still are the best choices that you should take into consideration. 

Eqiva and Meross offer some great features in the form of bluetooth smart, 7 days program, frost protection, easy installation and great compatibility with Alexa, GA, and mobile apps. The downside that is reported by a few users about eqiva is battery leakage and a bit noisy while Meross has limitations of not talking to your boiler.
