Tado X
Can you please advise if the Tado X product is suited for our situation. We want to urgrade and better regulate our hot water and heating.
We live in a 5 bedroomed house, currently it has 18 Radiators, 15 of which have old TRVs. The boiler is a Potterton Ultra with a separate water tank (Megaflow Cylinder). We have 1x Thermostat Danfoss TP9000 located in the utility room, we have a 1x Thermostat Danfoss TP4000 located in an upstairs Bedroom plus a 1 Danfoss TS2 remote sensor located downstairs. P.S. I am new to this forum and gratefull for any advise and recommendations. Thank you. Paul C.

I have just installed Tado X in a similar setup. 5 bedrooms, 23 rads with 20 having TRVs and 3 that were permanently on (in the hallway/stair) with the old thermostat located there. I also have a separate Megaflow hot water cylinder.
First, having radiators without TRVs isn't really the way to go with smart rad valves, so I retrofitted thermostatic valves to them all and ended up with 23 Tado X rad valves. The system works really well, but you need to consider whether any areas would benefit from separate Tado wireless thermostats. These give better control when you have large rooms, but come at a price and are not necessary for small rooms. I started with just one in the hallway, then ended up fitting 4 of these to rooms where they made a difference.
In my house, the second floor cools down far quicker than the ground floor, so heating was previously really uncontrolled with the old system (a Nest) shutting off heating when the hallway was to temperature, leaving the upper bedrooms cold. The Tado system completely fixes this.
A word of warning, however. When fitting the radiator valves I discovered that about 3 of the old TRVs were not actually working (rad valves around 25 years old and seized up), so needed to be replaced. Not too difficult, but be prepared for this.
Good luck.

RobinLB - please tell me you have at least ONE radiator without any sort of TRV valve?
If not, you need to fix that, because one radiator is required as a bypass between flow and return so you don't burn out your boiler and/or pump.
Also - old TRV valves can get stuck, but you CAN unstick them and lubricate, had to do this to a few, and they're working fine now.

Only if you don't have an auto bypass valve…
