Home Automation - Heating and Hot Water
 

I'm after recommendations.
I currently have the central heating fitted with the EQ3 Max system. Each radiator on a WiFi TRV, primary rooms have a thermostat and many doors and windows have open window detectors. All runs from an app on my phone allowing me multiple configurations (just us, 1, 2, 3 guest rooms in use etc.). What it doesn't have is a link with the boiler to switch on and off dependant on demand.
Any recommendations on a system that will control the boiler and hot water as well. It must be Alexa compatible as well. I will be selling my EQ3 Max stuff this summer and fitting the new system.

TIA.

Honeywell is doing a system with radio controlled TRVs that are managed from central console or smartphone. Additional room thermostats can also be added. Central console will switch on boiler when required. No idea about Alexia though.

But IMHO Nest is the best. It has ho radio control TRVs though, but this is not needed if you have manual TRVs that you can configure and forget about. I have 3 zones in the house plus hot water. 3 Nest thermostats control 3 zone valves on s-plan system plus hot water zone valve. Each zone has its own schedule. Wired installation, but wireless is also possible. Installed everything myself. Excellent app.

I think nest were also doing an offer where they gave you a free Amazon Echo Dot recently through British Gas, so Nest must be Alexa compatible

Currently looking at the Honeywell system. Thoughts?

Honeywell is making great stuff

I run a nuheat thermal store, which works brilliantly, albeit a departure from typical domestic installs.

It basically a giant hot water cyclinder, but full of central heating water.

Boiler runs on a standard thermostat to keep it topped up to temp as required. Also has inputs for green technologies, solar panels etc.

Then, your heating just draws off the hot water as required via the normal CH pumps.

HW is mains pressure, but heated on demand via coils inside the thermalstore, giving instant, endless hot water.

Much more efficient for dribbling out bits of heat here and there as the boiler only need kick in occasionally to blast things back up to temp. Designed with underfloor heating in mind, but equally useful for rads.

I bought mine second hand, installed it about 6/7 years ago now and its been great.

How many litres does it hold. Where it it sited?

Around 180 litres I think..... Mins located at the back of the garage, which has since become a utility room.

Its the size of a typical water cylinder, so not insignificant, but would remove the need for a regular hot water cylinder....

I was looking into the EQ3 max stuff as well. This looks like what you need.

It seems to be missing on a lot of other sites selling the TRVs, gateways, etc though which seems strange and if you search the box website for EQ-3, it doesn't appear! Would be good to know if this works. I don't see why not though. Hopefully save you swapping everything out as I like the look of the system.

My friend has the Honeywell EVO stuff fitted and it's very good although I find the valve heads a bit bulky (but then again, it's next to an ugly radiator so.....)

That is indeed what I need but no one has one!
I tried the manufacturer but they didn't reply to my email. I phoned Conrad and they couldn't get one!
