Ability to open valves within summer

Does anyone know if Tado has got a way to open the valves without turning the heat on yet?

Many boilers operate their pump once per day (mine doesn't) to keep the fluid circulated and exercising the pump. Without the ability to open the valves it means the pump isn't circulating the water around the full system which isn't ideal

At present what I do once a month or so (as a bodge) is run the internal pump mode from within the boiler settings to get the water flowing in the heating side and then set the heating to max with the max button. Because the boiler is in a diagnostic mode the boiler doesn't operate and ignores the command from Tado to run at max.

Not very elegant but at least it keeps the chemicals protecting the system circulating.

    You can open the valves if you make them independent of the zone controller so they don’t call for heat, but I don’t know of any way to tell Tado to pump the water without heating it. I just run mine on boost mode for a couple of mins every month, so far with no issues.

    I dismounted my valves over the summer months, thus leaving the valves fully open without any concerns regarding needless boiler ignition.

    As for periodic circulation, my Vaillant 831 seems to wake up periodically to run the pump for a short time - maybe 30 seconds or so. This is not the "comfort" feature for hot water, which is disabled. It's simply to keep the pump from seizing, I imagine. In the absence of an automatic pump anti-seize feature I would manually run a purge cycle to keep things moving.

    The boiler was installed 11 years ago and so far the only problem has been a leaking diverter valve. The pump itself has no issues. The system was drained and refilled last year with plenty of inhibitor and I check the Magnaclean every few months. No dramas there.

    I'd not thought about un-zoning the TRV's. Good idea if you only have a couple of them. I've got 14 of them so I think it might be more hassle.

    Removing the units is a good idea too, although I'm too lazy to do that :)
