While testing I found that the boiler was triggered to heat up the water. Thats not what you want. So the zone type selected does matter!  
I updated the instruction above

> Select zone type: Electric zone! If you choose a different zone type Evohome will also activate your boiler. You do not want that…

PS: this zone type is only available after upgrading to evohome firmware v2.0 (thats on the evohome not on homey)
