Heatapp! is a German made wireless control system using Z-Wave technology. Now for the first time, we can combine control of both radiators and underfloor heating on one platform. The installed price of a Heatapp! system is very favourable when you consider the savings in hardwiring, chasing, etc. in new builds and also makes it a feasible possibility for retrofits and upgrades. The controls use a free app called Heatapp!, just look for Heatapp! in the Google Play Store or iTunes. There is a sample app so you can try it out for free. This gives individual control over radiators and floor heating in up to 24 rooms – you can have up to 4 radiators per room.
