How much do you expect to shave off that with the changes you're proposing? Not enough to make it worth the trouble I'd imagine.
We use ~6700/6800 kWh/yr for 130sqm, so we are coming in at approximately ~52 kWh/sqm/yr. I think we could easily reduce that by >300 units with better controls
There's a chance you might interfere with the set up that's already installed and working well.
It's not working how they want to, so it's perfectly reasonable to explore alterations.The house is either at a very comfortable 21/22°C or it cools down well below this. I'd like to be able to maintain a steady 20°C
Indeed. But just making the point about being penny wise, and pound foolish. Sometimes we need to be careful about what we wish for. That's all.It's not working how they want to, so it's perfectly reasonable to explore alterations.
When the options and their costs are known then only the OP can determine whether reduced running costs and more accurate control to their requirements is worth the outlay.

You've missed the point entirely and managed to go off topic with the very first post. The system doesn't function properly because of 2 poorly calibrated stats. I specifically left out cost or payback because it is irrelevant to my questions. But in the scheme of things, 2 new stats would not be expensive.Indeed.

Yes, it is this exactly. In the downstairs living space, it is always warm and the stats don't have the control or resolution to drop another degree. And upstairs, I don't want the toddlers bedroom to cool down too much in winter because of a badly positioned statIt's not working how they want to, so it's perfectly reasonable to explore alterations.
Thanks @Buddyboy , that's what I am interested in. I probably don't need fully programmable controls but rather just more accurate stats but I will look at them.Originally there were just thermostats fitted, like your setup, and a controller similar to yours. I replaced the two thermostats with programmable thermostats, and set the controller to "on". I set the programmed temperature to various times of day, e.g. 16 degrees at night, and 20 at 9am.
Not a problem, I have an electrician in the family who can do it for meIt is pretty easy to swap them out, just make sure if it is 12 or 240 volts. And if you are unsure at all, get an electrician.
Not possible to swap sides, it backs onto the some dead space between the bathroom wall. If moving entirely to a wireless stat, does the control unit also need to change or get any upgrade/adapters?If it's on a stud wall next to the hall/landing, then you could just swap sides. if that is not possible, then it is possible to change to a wireless one.
Yes that's what I'm thinking, even in the same location, a more sensitive thermostat upstairs would actually respond to a setting of 19 or 20°. Any suggestions for brands or models?It's likely that better quality and better placed thermostats might solve the issues here
Any other room upstairs really, the toddlers room would probably be best.Is there a location that maintains a more typical upstairs temperature? Perhaps even the toddler's room might be best for now?
How do these work with the existing 2 zone controller? Does it effectively heat independently as a 3rd zone or does the smart TRV still depend on the zone being on?you can get smart TRVs that would allow you to further fine tune the needs for more important rooms over the course of the day. As you already have TRVs, most of those would be a simple job to replace as the heads are usually interchangeable without releasing any water.
Drayton are a pretty reputable brand.Yes that's what I'm thinking, even in the same location, a more sensitive thermostat upstairs would actually respond to a setting of 19 or 20°. Any suggestions for brands or models?
They will work independently of the controller. What they will just allow you to do is reduce the heat going to certain rooms at times you don't need it. The boiler would still need to be triggered from the main thermostat to call for heat to that zone, they will just allow you to fine tune the heat that certain rooms will get to by shutting down water flow to just the rad they are installed on.How do these work with the existing 2 zone controller?

Great, thanks for that @Micks'r, I was hoping you'd contribute . One further question, does the control panel need an upgrade or add-on to support the RF ?The programmable wireless chronostat I use is the COMPUTHERM Q7RF. Works a treat, is very accurate and be moved depending on needs.
There are several different types available and should be no problem to exchange once the voltages are matched like for like.
Perfect, that's what I thought would happen. The zone needs to be on before they takeover, i.e. they are better for keeping rooms cool when the main thermostat is on but if the main thermostat is off, they can't doing anything.The boiler would still need to be triggered from the main thermostat to call for heat to that zone, they will just allow you to fine tune the heat that certain rooms will get to by shutting down water flow to just the rad they are installed on.
Yeah, they make more sense in mixed use zones where you might want a subset of rooms heated at different times.For now I don't think I'd need that level of control and the TRV's we have do a pretty good job as it is. But maybe we'll add it after I've changed and moved the main thermostats as it might make sense for the main bedroom
No, control panel should not need any upgrade. The new chronostat (base unit and wireless controller) would replace the timer and thermostat so just make sure that the new chronostat spec is compatible with the current setup (some setups are powered so check what voltage and others are volt free).Great, thanks for that @Micks'r, I was hoping you'd contribute . One further question, does the control panel need an upgrade or add-on to support the RF ?
One further issue we have is that because the main thermostat is in our main bedroom for the upstairs zone, our body heat can maintain the room temperature at night
