Rated 5 out of 5 by from Changed how we live. I installed the system with 14 TRV's in December. It was easy to install and setup. I am not sure yet whether or not it is saving us money but it has made a room that we could never get comfortable much more liveable, only when we need it to be worm. The system has also allowed us to reduce the condensation in our bathroom from when we shower by heating just the bathroom for half an hour before we use the shower. This stops the water from condensing on the walls before it is removed by the fan. I am also able to sleep better as the bedroom does not over heat in the morning, which used to wake me up before the alarm feeling very uncomfortable. Now the room is only brought up to a comfortable temperature just before the alarm goes off and the rest of the house that takes longer to heat can get to temperature just before we need it. The bonus is that the parts of the house that we don't need heated just stay at the minimum temperature set and therefore save energy. Our boiler seems to run for much shorter times now.

Rated 1 out of 5 by from 4 years and no longer working The Hub now refuses to connect to the internet and the support from Drayton/Schneider is poor. The wall thermostat has an intermittent fault with the display. Build quality is extremely poor and not worth the money.

Rated 2 out of 5 by from Wiser - Buggy App Good system components and price but let down by a buggy app. System will switch ON automatically when in Manual mode and will then prevent you turning the heat OFF manually. A number of times I have returned to a heated house. Wiser have known about this fault for more than 2 years but don't consider it a significant problem ! I'm looking around for an alternative system.

Rated 5 out of 5 by from Does what it's meant to Found this to be a great addition. We can now switch on the water or heating from bed. It was easy to install as it fitted into our existing back plate, but I had checked this before buying. App is very easy to set up and use. The only thing is there have been a few times when the app hasn't been able to find the hub, but this may be our Internet, so I marked it down by one for reliability. The last time this happened I reset the app and everything, it has been fine since then.

Is this compatible with a fire bird oil boiler 10 years old

Asked by: Rrrt
Wiser will work with all common boilers using a UK standard back-plate, except gravity fed systems or boilers requiring manufacturer specific controls.

Is this compatible with a BossTherm BUP2 Controller's "standard" baseplate?

Is this controller a plug-compatible direct swap for a BosTherm BUP2vs "Standard" backplate? (providing the existing themostat is turned fully up or wired out)
Asked by: IanbH
Wiser Thermostat Kit 2 would be a direct replacement. Linking out an existing Room stat. There are three ways you can achieve this: 1. leave the thermostat where it is, and just set it to its highest setting, therefore giving it a permanent open circuit. 2. Remove the thermostat and link the LIVE in to the LIVE out, using a terminal box. Then hiding this in the wall. 3. Trace the wires from the thermostat back to the wiring centre and link the LIVE in and the LIVE out at the wiring centre. Allowing you to strip out all the wiring to the room thermostat.

can you install 3 thermostats to control 3 zone valves in addition to the hot water

Asked by: oddjobjoe
The Wiser kit 3 has 3 zones, two heating and one hot water. Zone valves are directly wired to the electrical terminals/zones on the Wiser backplate. There is no 4th terminal/zone available on the Wiser for your 4th zone valve. The thermostats need pairing to a zone and so a third thermostat will not have a seperate zone to pair to.
