Upgrade to wireless smart heating

[browncow5]

I've just moved to a new house and the heating system is a little confusing. We have an old dial thermostat which seems to control the radiators and a honeywell wireless unit that controls the under floor heating in the lounge.

I had a hive system in my old house and would like something similar, particularly so i can put the thermostat in my daughters bedroom so that the heating comes on when it reaches a set level in the night.

I installed that myself, as it was a combi boiler and relatively straightforward. This place has stuff all over (see pictures).

Whats the best way to do this. It seems there is already a honeywell receiver in the cupboard with the water tank(s) (complete with suspect stains on them), which i assume is driving the underfloor heating handset. Is it possible to just purchase another and connect so it does the radiators as well?

Appreciate any advice

It’s an unvented cylinder which you may need a G3 registered engineer if planning on a dual channel Hive, if not, then a single channel Hive should be sufficient.

Ok, good to know i shouldn't be touching anything. I did purchase a Tado X wireless starter kit to replace the Honeywell ST699, am going to leave the underfloor heating as is with it's own thermostat.

Will get a gas safe engineer to install it

Doesn't have to be a gas safe registered engineer, someone with a G3 (building regulation which covers unvented cylinders) qualification

Ah ok, thanks again

I hate the word Smart. As people think is means very diffrent things. A geofencing system may turn the heating up once your phone moves to the cell local to your home, or it can be set for x miles away, or it may not have geofencing at all, and you may need to manually set with your phone.

I gave up with geofencing, and now I use simple programmed (timed) changes of set temperature for each room. With 14 programmable TRV heads.

Only one of my TRV heads can cause the boiler to run, plus 3 wall thermostats, which I find "Smart" enough for what I want.

In the main central heating works on the near enough engineering idea, it would cost too much to make it perfect.

I have one problem room, the TRV is on a radiator next to the outside wall, so it switches on too soon, I am monitoring what it does, before deciding if worth changing it.

My tank is not sealed, but I have no control of the temperature once the central heating is running, it can get as hot as the central heating water, but it does not seem to be worth while to alter it. Summer heated with off peak or solar.

So step one is decide what you want automated, step two is work out the cost, and step three is to modify what you want to keep cost within limits.

You have some sort of Vaillant boiler, though the model is not obvious. Vaillant offer some well integrated, and clever control system, which perfectly match their boilers. It might be worth your while looking at those, and they will replace most/all that you have there.
