Do I need more than 1 Hive thermostat for multiple zones?

yannakis

Not sure if the setup is called 2- or 3- zone, so let me describe it and you can probably clear this bit up for me before going any further. Gas boiler with controls for heating downstairs, heating upstairs, and hot water.

I saw Bord Gais are giving the Hive thermostat for free with certain plans, and I'm interested but the question is: do I need more than one device for the above setup?

Hi

Looking for some advice on a Hive install.

3 storey house, each floor has a thermostat either on the landing or in the hall.
2 Gas Boilers, one for water, one for radiators controlled by mechanical timer switches. Water tank with Immersion.

Putting the Gas for the water on for am hour in the morning and half hour in the evening seems to give us enough hot water for a family of 5.

House always seems to be too hot or cold & heating bills have been high in the winter.

What setup should I be looking at?

Thanks.

It depends on where the motorised valves are located, it would involve routing cables from the valves back to where the timer is.

Sometimes it maybe possible to have the hive receivers in the hotpress where the valves are (in some cases) and only have to run a single cable back to the timer, but each installation would have to be assessed on its merits.

Thanks for the reply. Would it be easy enough to fit the auxiliaries from the 3 motorized valves to make it a proper multizone? As it is, I have the problem that although my sitting room downstairs is obviously hotter than the thermostat setting, it is not turning off the boiler even when the other 2 stats are off. I'm really looking for more control over the system.

Hive will only replace the timer as is, so if you cannot control the upstair/downstairs heating independently from the current timer, Hive will not be able to do this either.

It sounds to me that you motorised valves (controlling upstair and downstair and hot water) may not have had the auxiliary switches wired into your system.

Hive dual system could replace your current timer, but your app control would only be 1 heating zone and 1 hot water zone, and both your upstair and downstair stats would have to remain in place.

Hive receiver replaces your timer, and then you have a remote hive thermostat (battery operated)

If your timer had separate upstairs/downstairs/hot water, then you would need hive multizone:

Dude pack: 1x Hub 1xDual receiver (does 1xhot water 1xheating zone) 1xThermostat
Additional Zone for multi zone: 1xsingle channel receiver 1xThermostat

Hope that helps.

Hi DGOBS, I have just bought a house and am interested in the hive thermostats. I have a similar setup to yannakis. I have a heating controller (very simple timer clock with 2 switches, 1 for heaing/1 for HW), this is on the wall in the utility. I have a stat on the wall in the sitting room, another in the main bedroom upstairs and another on the hw cylinder. Would i need 2 hives? Where do they go? does one of them replace the heating controller? if so, does it have to go in the utility where the old controller was? Sorry for all the questions. Thanks in advance.

I'm a Hive guy, so wouldn't be objective to answer that!

I love Hive, I have 3 heating zones and a hot water zone, if your house is zoned, 100% spring for the extra zones.I also have hive lights, plugs, motion sensors and window/door sensors. (my cameras are in the post) and have them all linked through an Amazon Echo (you can also use Amazon Dot) so when in the house, I can ask Alexa to operate any of my devices, I also have created recipes, such as when one of my kids goes via the hall to the bathroom between 10pm-6am, the hall light automatically comes on at 10% power for 5 minutes (you can also access a log of movement) my kids phone chargers are plugged in via a Hive plug, so when they fall asleep in the bed with the phone on charge (as they always do!! grrr) I have those plugs timed to power off at 11am each night.

Thanks @DGOBS, very straight forward.

Do you believe it's worth the extra monies?

Also, would you recommend an alternative "smart thermostat" rather than the Hive?

DGOBS

Yes you will, for a 3zone like you have mutlizone is required.
The offer covers 1xheating zone and 1xhot water, for the additional zone it's an extra receiver and thermostat required (€119 installed)
