Room by room automated heating control system

[Worcester]

I have installed and recommend the Eaton xComfort home automation gear! mainly wireless so simple to install offers complete control from a free App you can download to your phone or tablet. There are plenty of xComfort videos on youtube to look at and get an understanding if it suits your client, I have installed xComfort myself mainly for the Norwegian Market.

Still don't see how that on it's own provides the room by room control - it still needs to interfaced to an existing multi-zone system and if that doesn't exist as in 99.99% of UK homes it doesn't provide the room by room control. I'm still haven't come across anything else other than the Honeywell Evo system that does just that.

I'm possibly in the market for something like this as well, given the layout of our house it would definitely benefit from zoning. Something not clear on any of these, except the Honeywell, is whether they interlock with the boiler. I think that's essential - if none of the zones are calling you don't want the boiler idle firing.

Do any of the other systems mentioned here have boiler interlock?

Honeywell Evohome is the only one I have come across that can totally multizone an existing system. The one downside is if you haven't got TRV's fitted or the heads aren't compatible then it will require these to be changed. It's not a cheap system if you go the whole hog with it. If existing system has 2 CH zones and TRV's the payback time will take many years imo

As a retrofit, from our research, it is only the Honeywell Evo that offers boiler interlock - we still keep looking!

This one MAY offer it, ( Istabai Home Automation products ) though both the manufacturer and suppliers have been tardy to answer our questions which doesn't bode well, so we'll stick with evo

Or in a refurbishment or new build environment you could use underfloor heating controls as mentioned before.

Payback comes through convenience and smart control. We regularly have 8 zones configured on the evo systems, with a single controller you can go up to 12.

Hi All

just priced up a job with lighting & heating controls we are looking to use Lightwave RF by megaman.
this uses trv's that can be controlled over internet through app.

Before all these apps etc, 10 years ago zoned my house, because of using open fire....simple 22mm water valves controlling flow to each bedroom and main living room radiators. stat in each room, opening valve...micro switch in valves all wired in parallel to fire up boiler. So when living room fire is blazing away, the heating is off downstairs, but still keeping bedrooms heated. Also bedrooms timed to only come on from 9pm to 12am and 6am to 9am. Only thing to remember with this type of system, is to have a least one free flowing uncontrolled radiator, mine is the landing and bathroom towel rail

Mi Marc8, when I spoke to megaman last week, the TRV's weren't yet avaialable - do you have a date?

Also how did the price compare to Honeywell EVO?

I guess my biggest concern would be support in 10 years time..

Hi Worcester
should be available shortly I have been told we are using the lighting on a project starting today, will speak with rep later today & post on here

Before all these apps etc, 31 years ago I zoned my house, easy with Honeywell 4043 2 port zone valves controlling flow to all 8 zoned rooms. Thermostats in each zone are fed from programmer for ASHP ( heat pump added 2012) & optimiser/stat ( if low COP`s then gas boiler is operational), on valve opening, the micro switch in any valve will call for heat, all wired in parallel. One thing to remember with this type of system, is to have a least one uncontrolled radiator, mine is the hallway and bathroom towel rails. Also fitted with micro switches on windows, so that if any window is opened then the heating goes off in that room, no point having heat going out - lost.
