At the moment most UK energy bills when based on the capped rate are a rip off, it’s the way the energy is priced that is the issue. I am with Octopus and have been since late 2021 so I can compare my bills , at first I was on the capped tariff but I have been on the tracker tariff since Jan...

I did. The first year of having a smart meter saved me about £800 in energy cost despite using slightly more energy, due to having a smart tariff which is not available unless you have a smart meter.

Ok, so did the electrician take a photo before they removed it?

Could be wired incorrectly, can you post a photo of the Hive wiring and did you take a photo of the Honeywell wiring before you removed it.

Unfortunately there are some BUS grant harvesters out there who just add the grant money to the quote by inflating their prices. This is an ongoing problem whenever the government offers grants for anything but is compounded my the MCS monopoly.

Panasonic heat pumps seem to get good reviews online and are one of the cheaper heat pumps. Maybe you could buy the heat pump and then pay a plumber and electrician to do the installation, forget about the BUS grant.

What about a Vokera Pinnacle S, I think they modulate very low.

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.
