Are not Baxi in tight with Nest now with Open Therm (or not).
But Baxi was not the manufacturer; that was Remeha in the Netherlands. All Baxi did was stick their own badge on the front instead of the Remeha badge.

It's interesting at the moment and a bit of a hiatus between manufacturers, the installers and the customers. The market will win in the end but who shapes it will be the thing.
Yes the manufacturers want their own controls on their boilers and with incentives can bring the installers to this but in the UK there are many independents whereas in Europe the self employed are often an agent for a manufacturer and tied to them. I suppose as long as Holland says it wants inter-operation and the UK remains mostly independent manufacture's will have to decide whether they'll go their own way and possibly limit sales revenue or open up and incur the cost of costly troublesome support issues.
Honeywell having lost or given the OT away now have their own which is already built into their ON/OFF stats but have to get the manufacturers onboard to include it into their boiler software. Some companies have OT stats which or both OT sand ON/OFF but only tell the installer about the ON/OFF part. Never dull this industry.
With Google the customers are a little more aware of the options available so now instead of being in the hands of the installer or manufacturer they are able to research a little more deeply and easily. Whether it makes a difference remains to be seen.

Yes, I was well aware of the merger a few years ago to form BDR Thermea. However the companies in the group are allowed to pursue their own agenda, so far as manufacturing and products are are concerned. It is not like Vauxhall and Opel, where both brands are built in the same factory and are identical, apart from the badge on the front.
So, no, I am not being disingenuous.
Back to the OP a Worcester system boiler with an internal diverter valve and their Wave control will give you what you're after.
Thanks. Had a look at the wave but it cant handle more than one zone according to WB which seems an oversight.
Why do you want to zone. If you haven't got a big house so there would be next to no benefit.
Previous house I found a difference from one floor to another. This one probably more so, as a mixture of UFH and rads.
Zoning is the key to everything, all this modulation via an outboard controller adds virtually nothing by comparison.
Modern gas boilers modulate reasonably well by themselves. Zoning can save 30% of the energy bills, none of the weather comp or OT units can deliver anywhere near that.
NB: Worcester published a bulletin in 2009 which showed their FW100 weather compensator working in a zoned system with internal diverter valve fitted. We've fitted one of these set ups. FW100 is about to be withdrawn but it should also work with SenseII.

I would only chip in that I don't think there is a key to everything, boilers are very very good on their own and all that can be done is nibble a bit extra here or there with better controls or maybe zoning,. Yet to have personal experience of zoning with the latest controls and that's when I make up my mind. Anyway I do have a dislike fot the easily banded about 20, 30, 40% saving some manu's spout. Too much depends on customer, property and circumstances.
A surprising umber of my Evo customers have emailed me with savings, around 30% is not untypical.
And I've been using 16 zones since 2003 myself in my own house, so have practical long term experience.
If you haven't fitted one in your house, you of course have every right to be sceptical. However don't let your tardiness put off others unjustly.
It is easy to forget zoning simply makes your house much, much smaller. Of course it will be cheaper to run.
It wouldn't work in a house with every room occupied 24/7, but few of us live in such a scenario.

The rooms don't even need to be occupied. If the door is left open, heat will enter the room, even if the TRV or thermostat in the room is set to a lower temperature, so eventually all rooms will be at approximately the same temperature.
