Anyone using Hive plus TRVs? I have a question

[Relentless81]

Long shot but here goes, hoping someone has a similar setup that can confirm my theory before I spend £200 on TRVs

I have two rads without TRVs, one in the office and one in the hall near the thermostat.

If I add Hive TRVs to all other rads and set the schedule to frost protection in the day and thermostat to 20C the two rads without TRVs will come on and the Hive TRVs will prevent all other rads from coming on.

If the schedule then changes in the evening for the rads with Hive TRVs to match the thermostat at 20c all of the other rads will function

Is this correct?

What I am doing here is not using the Hive TRVs to call for heat or "heat on demand" but actually using them to prevent the rads they are fitted to from firing up so that the dumb rads in the office and hall way are heating up only.

Thanks

Oh no, sorry to hear that. I did read about people having issues with them but was hoping it was early adopter issues not the other way around!

Ok I will avoid them in that case and consider either moving to Tado for everything or just getting an oil heater for the office and keeping the heating off in the day time

Have no issues with tado. 6 trvs, 2 wireless stats, and hot water control

Took a while to get set up properly, iron out routines. Have weird calibration issues etc. But now it's rare for an issue.



Went with tado because of issues I read about with hive.

Good to know, such a shame about the Hive TRVs because the thermostat works perfectly for what I use it for and they would have been a great addition

I had a look at Tado and the cost of swapping out the thermostat plus the TRVs for this point in winter isn't worth it right now so I will revisit toward the end of next summer

I have absolutely no such issue with my Hive TRVs and they do precisely what you say in the OP.

I know Tado is a fan favourite on this forum so the number of folks recommending Hive is always very low.

It's the same in the Amazon reviews completely split between "works fine" and "have a mind of their own" not willing to take the risk on 5 of them right now though

@dLockers yes I think so thanks, in my case I want the TRVs to prevent certain rooms from heating at certain times and then change on a schedule to come on later in the day.

I really don't want them coming on when scheduled not to as that defeats the purpose of buying them and will cost us more on the bills

Also I don't want them not coming on when they are scheduled to because that will my prevent my young sons room from heating up which is bad for him and for me due to grief from the Mrs so I'm just not sure at this point if it's worth the risk.

I also noticed Amazon don't seem to be stocking them as much and are no longer available under Prime, whether this is a stock issue or down to high volume of returns i don't know but doesn't look good

@dLockers

I have three rads without TRVs, dining room/office, bathroom and main hallway. These would run off the thermostat during the day and the Hive TRVs would prevent the other 5 rads from heating up.

At the moment we are heating all rads all day via the thermostat.

I could manually go round twice a day switching the current TRVs on and off but ain't nobody got time for that.

Cost savings it would take a good few years to rake the money back at current energy costs but part of me just wants to mess about with the tech and get it setup and working as I've imagined it to

I haven't had issues with running schedule or using them as you've described. The only thing I found to be a problem, was the noise of the valves when used in a small child's room. On opening and closing the motor was too much of a disturbance for them. I don't know how other brands compare but they are a bit noisy.

That's a major issue to add to the negatives, kids wake up if a spider farts in the loft

 

[Relentless81]

Yeah that's a definite no for these I think.

I'm going to make a note of all the TRV settings for each room and manually switch them on and off on cold days and have the heating up a bit more in the day. I'll get sick of it but I'm going to wait for this tech to mature before investing.

Thanks for the advice all.
