We Compare: Nest Thermostat | Hive Heating | Worcester Wave

Quick Guide Summary

Which do you buy? A Nest thermostat or your boiler manufacturer’s own smart thermostat?

Some mainstream boiler manufacturers have developed their own smart thermostats that work exclusively with their range of boilers. When you are considering a new boiler with smart controls, you can choose between popular third party brands Nest or Hive or opt for the manufacturer’s own smart controls. We have undertaken our own review of boiler manufacturer’s own smart thermostats and compared their price and performance with that of Nest and Hive. How else can we help? For more on standard heating controls, read our Guide to Thermostats, Programmers and Timers. Research A rated central heating boilers and many other heating topics on our Information Hub.

Which Boiler Manufacturers offer Smart Heating Controls?

Only Worcester Bosch, Vaillant, Glow Worm and Viessmann currently manufacture their own smart heating control unit. If you wish to install an internet control option with a Baxi, Potterton, Main or Ferroli boiler for example, then you will need to use an independent brand such as Nest or Hive.

Prices

We have first compared the price of the base unit, which will only control the heating. With the exception of the Viessmann unit, all controls require additional wiring or external diverter valves to also control the hot water. A total price for heating and hot water controls is shown at the base of the table.

Advantages to using a Manufacturer’s Smart Control

  • the controls are designed to go with the boiler and their technical helpline staff will understand the set up more specifically, particularly in relation to the hot water control options.
  • Worcester Bosch will extend the guarantee on their WAVE controls to mirror that of the boiler if installed at the same time (8-10 years) and Vaillant have plans to do the same, although this is not currently the case.

Disadvantages to using a Manufacturer’s Smart Control

  • None of the boiler manufacturers’ controls work with Smart Radiator Valves – only the Nest currently has the capability to do this.
  • None of the manufacturer controls offer any add-on functions. Both the Hive and Nest will do additional heating zones and provide sensor and geo-location features to bring the boiler on when you are close to home.
  • The controls are more expensive for combi boiler systems and there is some reduced function compared to the Nest and Hive. (The costs level out a bit when introducing hot water temperature controls)

Our Top Tips

  1. Not all of the boilers in a manufacturer's range will work with their own smart control - check compatibility
  2. Use the Worcester WAVE when fitting a new Worcester boiler to get an extended guarantee of upto 10 years on the controls - well worth the extra cost.
  3. If you are fitting controls retrospectively on an existing boiler, then a Nest or Hive are cheaper than manufacturer smart controls with more functionality
  4. If you want to fit another popular boiler brand such as a Baxi, Potterton, Main or Ferroli then your only option is the Nest or Hive.
  5. If you want to fit Smart Radiator Valves to better ‘zone’ your heating system then your only option is the Nest.
  6. If you want to control your hot water temperature from your smart phone then additional components are required - see tables.
  7. If you want to control more than one zone via the smart control then you have to use the Nest or Hive controls (unless you are opting for a Viessmann boiler).​
