Nest vs Hive vs Tado vs Honeywell: Which is the best smart thermostat?

In my opinion, Nest is the best thermostat. Hive isn't actually a thermostat because it does not learn anything as far as I'm aware Hive is not opentherm compatible. Nest is also far easier to use. You will never require to set up a heating schedule manually. The nest controller will automatically set one up for you because it has a motion sensor built into the device.

At what temperature do pipes freeze in the UK?

Water begins freezing at 4 degrees Celsius. This is why the minimum setting on any modern heating control is 5 degrees Celsius. The freezing process is completed if the water temperature is at 0 degrees Celsius. If you live in an area with very high water pressure this will slightly lower the freezing point of the water in the pipes with high water pressure.

What are the disadvantages of installing a system boiler?

The short term disadvantage of installing a system boiler is the cost of the installation. Due to requiring a new unvented hot water cylinder being required the material costs will be hire. Also the unvented hot water cylinder will require servicing as well as the boiler. Space for the boiler and unvented cylinder is also a factor to be considered. I would always recommend fitting any unvented hot water cylinder on the ground floor just in case the cylinder or its safety features developed a major leak.
