What is the best smart thermostat in 2020?

This question is difficult to answer, as there is no suits all recommendation. There are numerous differences among the smart thermostats and which is “best” comes down to what it is paired with and the end user needs. For someone looking for relatively basic feature set, but with option for remote control via a smartphone then Hive is an ok option at its price point. Some boilers are compatible with opentherm which gives the smart controls the ability to modulate the burner based on demand and other external influences (e.g. weather compensation based on outside temperature/forecast). These devices when connected correctly with a compatible boiler offer the best in terms of efficiency improvements. Unfortunately even if a device states that it is compatible with opentherm (which is a communication platform), it doesn’t always mean you will gain the full feature set offered as its implementation is not unified. I recommend that the “Best” thermostat is determined on a case by case basis with a conversation with the end user, identification of what boiler is present and assessing what would be the best suited for the individual circumstances.

My central heating isn't working but hot water is, why?

This could be due to a number of reasons dependant on the type of boiler and system controls in place. It could be any of the below -Batteries low in wireless thermostats -Faulty relay/switch in controls for heating (room thermostat, programmer) -Faulty component/seized component in the diverter/motorised valve -Faulty sensor -Air in the system/airlock -Restriction in heating pipework Etc.

Why is there no power coming to my boiler?

There are a number of reasons why power may not appear to be coming to your boiler. Some example scenarios are below: -MCB or RCD protection has tripped cutting power supply to boiler circuit. -Fuse that supplies boiler has blown. -Some boilers only have a switched Live supply, meaning it could be an external motorised valve,programmer or other system control causing the power supply issue -There could be power going to the boiler, but no display/lights showing due to a faulty component/blown internal fuse. Sometimes this may be an intermittent problem, which can be a component showing signs of failure, or in the event of tripping RCD’s, earth leakage. Any of the reasons outlined should be investigated further by a qualified engineer to determine cause, as it is rare for a fuse/safety device to fail without reason.
