I heard of a few people moving off the tracker tariff last month but regretted it and were able to switch back onto the tariff immediately, according to the T&C’s there should be a 9 month wait.

From what I recall of your heating controls I think you have too little consistency and too much conflict. If it was me I would just go with one control system, like Wiser, and use a mix of Wiser TRV’s in the most often used rooms and conventional TRV’s everywhere else. If you need more accurate...

It’s a mine field choosing a boiler. Every boiler has its promoters and detractors, what one person says is great another says is terrible!

In my case I have a conventionally designed 2 story house, by conventional I mean it is roughly square. Originally the heating temperature was controlled by a mechanical bi-metallic thermostat that overshot and undershot all the time causing roughly 4c swings in temperature. This wasnt...

Ok ,he’s an idiot then! :giggle:

Maybe he tested the ev and the air pressure was to high so he released some of it.

@ericmark The graphs I posted are from Home Assistant, the wiser app is a bit basic in comparison. You can see how the Wiser hub is setup by going into the Wiser Heat app, selecting devices and then selecting the hub. I removed the Wiser TRV’s to simplify my heating system as I have a pretty...

The Wiser algorithm is a bit of a mystery to me so I have attached a screenshot from yesterday between 06:00 and 11:00. There are 3 graphs, the first is the boiler firing as requested by the Wiser hub, as you can see there are 3 cycles per hour. The second graph shows target and current...

On my Wiser system I now only have a single room thermostat having now removed all the Wiser TRV’s and replaced them with manual TRV’s. I also monitor the Wiser hub with Home Assistant so I can see in detail exactly what happens when a thermostat calls for heat and how the Wiser hub reacts. The...

These new TPI thermostats don’t seem like being turned up by less than 1-2c. I have found with my Wiser thermostat that if I want to increase temps by less than 1c the Wiser hub doesn’t react and fire the boiler by up to 15 minutes or so. Presumably the hub needs thinking time!

Looks like a Siemens RWB2E

You are getting manual TRV’s and so called “smart” TRV’s mixed up. A manual TRV will not shutdown the boiler and is a temperature limiter, a so called smart TRV if connected to a device that connects to a boiler does have the capability to shutdown the boiler. This is why you never have a manual...

The rear tyres on my summer car are dated 2009! They still look ok to me.

The room thermostat controls the heat in the room and stops it overheating. If a manual TRV, or any TRV not controlled by the room thermostat, is also in the room then it may turn off the radiator before the thermostat gets to temperature, in which case the thermostat never switches the boiler...

I need to remove the end cap of this radiator valve but for the life of me I can’t get it to budge, should the end cap unscrew or prise off? Thanks

It’s messy but not uncommon unfortunately.

What you are experiencing is exactly what I was saying in your other post. It’s a waste of energy to heat one room/radiator hence why I grouped together enough radiators TRV’s so that when the boiler fired it was worth it. I now believe it is better to allow a master thermostat to fire the...

The improvement would be having all the TRV's managed from a single app rather than multiple apps and access methods but, as I said, this comes at a £ cost which isn't going to be small. I don't like multiple thermostats having the ability to start the heat source potentially just for one room...

Replacing all your existing TRV’s with Wiser TRV’s will be an improvement on what you have now but at a cost. I’m not a fan of micro zoning and have replaced most of my Wiser TRV’s with manual TRV’s to act as temperature limiters. I think you have two distinct areas heated from a single heat...

Fortunately I use Home Assistant to manage the heating so not much use for the app. HA really shows the app for what it is, I.e not great.
