Smart thermostat installation in Portsmouth
Hive, Google Nest, tado and other smart controls fitted by heating installers covering your Portsmouth postcode.
Most Portsmouth homes have a gas combi, which makes a smart thermostat a straightforward upgrade. The right model depends on your boiler, whether you have a cylinder and whether you own or rent.
About 35% of households in the city live in flats, where one thermostat usually covers the whole home. Terraced houses on two or three floors gain more from controlling rooms separately.

Renters and HMOs
With almost half of households renting, many people will need the landlord's permission to change controls. Shared houses can benefit most, since one smart thermostat with a schedule stops the heating being left on in empty rooms.
Some landlords fit smart controls themselves so they can spot problems early, like a boiler that keeps losing pressure.
What your boiler supports
Most thermostats work with any boiler as a simple on/off switch. OpenTherm-compatible models can modulate the boiler, running it at lower temperatures for longer, which is more efficient.
If you have a cylinder, choose a thermostat with hot water scheduling.
Smart radiator valves
These replace normal thermostatic valve heads. They let you heat each room to a different temperature, which helps in houses where the front room runs cold and the kitchen hot.
Getting the savings
A smart thermostat saves money by not heating an empty house. Set it up with your actual routine, use the away mode, and let it learn how long the house takes to warm up.
Ask the installer to lower the boiler's flow temperature too. A combi running at 55°C or below condenses more of the time and burns less gas, and many are left at the factory setting.
Portsmouth homes and what they need
Victorian and Edwardian terraces
Fit the thermostat in the hallway or living room, away from draughts at the front door.
Converted houses and purpose-built flats
In a small flat, a single smart thermostat is plenty. Check Wi-Fi signal near the boiler before installing.
1930s semis on the mainland side
Hot water control matters here, since many semis still have a cylinder.

Questions people in Portsmouth ask
Will it work if the internet goes down?
Yes. Most smart thermostats keep running their schedule locally. You just lose remote control until the connection returns.
Who can fit one?
Usually a heating engineer. Nothing on the gas side is touched, though the thermostat or its receiver is wired into the boiler's control terminals.
Can I control the heating in an HMO room by room?
Yes, with smart radiator valves on each radiator. Some systems let a landlord set a maximum temperature while tenants adjust within it.
