Change the thermostat after isolating power to the heating system. It’s a very easy and cheap thing to do.

We have a fully insulated HWC and pipe work in our airing cupboard yet the temperature is always around 30c. Only the valve bodies are exposed.

Our heating has never been off. The house is set for 20c in the morning and 21c in the evening with a setback of 18c, last week the boiler fired for heating in the evening but only for very short periods. I think last week was the first time the heating has come on since last March.

To add to the above post..... the flame symbol on either the Wiser app or on the Wiser thermostat only means that the thermostat is in a calling for heat mode and will not necessarily mean that the boiler should be firing as this depends on where it is within the time slot.

Are you using a wiser trv in the bedroom or just the wiser thermostat? It is normal for there to be a delay with firing the boiler due to how wiser works, this is why you shouldn’t mix n match heating controls. The gas or oil boiler setting is in the wiser hub and would have been configured on...

You guys are missing the point. This is not about setting policy or planning for something that is 4 years away, even if immigration is still a problem then. Farage is a thorn in the side of Labour and Conservative alike. These statements are a message to the present government, whilst appealing...

The immersion will have a built in thermostat set to 60c. The immersion should be connected to a switched fused spur and normally this is turned off.

The HW cylinder is heated by the boiler, the immersion is for when the boiler is not working and is normally manually operated.

If you have a Wiser TRV in the same location/room as a Wiser room thermostat then the room thermostat takes over temperature control and requests for heat. The TRV is just used to open and close the radiator valve as instructed by the hubr.

You need a v2 hubr for temperature/humidity sensors to be supported. The new hubr was released a few weeks ago.

Is this on your Wiser system? If so just add a Wiser room thermostat to the room. Or if you have the newer version Wiser hub add a cheap Wiser temperature/humidity sensor to the room.

Legionnaires disease is only an issue when water is stored for long periods, this isn’t an issue in a domestic environment as water is regularly replenished.

I have had my Wiser system for three winters and have been reasonably happy with how it has performed. There are issues but I have either found workarounds of have just accepted them. Drayton have recently released to the UK the v2 hubr so I have "upgraded" my v1 to the v2 but as there is yet...

Yes

My experiences have been discussed before but in summary having a smart meter has enabled me to be on the Octopus tracker tariff which last year saved me a ton of cash in energy costs compared to the previous year when I was on the standard capped tariff.

The Wiser system has all TRV’s talking to the hub but now there is a v2 hub available that can talk to a simple and relatively inexpensive room thermostat which works in conjunction with the TRV.

Unfortunately you appear to have come across one of those tradespeople who shouldn’t be in business.

It’s probably just modulating down as it doesn’t need to provide maximum heat. My rubbish Worcester Bosch is the same, it rarely gets to the set flow of 65c and generally stays below 55c.

Buy Vaillant controls, 3rd party controls are inferior when used with a Vaillant boiler.

All I have found is Octopus Compare by M4 Consulting Ltd for IOS. It has promise but is a bit slow to update with tariff changes and only appears to work with electricity tariffs.
