Grant Vortex Boiler with Hot Water Tank - Tado Wireless EU Version

Hi there,

I bought Wireless EU version for OpenTherm feature but now I am wondering if it will work, if so how it should be wired.

We have Grant VOrtex oil boiler and hot water tank.

Thanks for info, recommendations.


  • If you’ve got a hot water tank do you not want Tado to control it? If so you’ll need the uk version of the wireless receiver. Gas system boilers usually can’t use digital connections like Opentherm and I suspect it’s the same for oil system boilers.
