Hello all
I have bought some Heatmiser 12v Network Thermostats and need to use one of these to actuate my underfloor heating (240V/2KW so that is roughly 8A).
I am therefore looking at 12V Relays or Contactors that would be able to switch this on. From reading through some of the threads, it seems a relay would be better if possible. I have found the following from Maplin which is 15A so lots of spare capacity:
The bit that concerns me is the "Maximum switching power 450W resistive" - sounds like it won't handle the load or would it? (Maplins also do a 30A one but the resistive is 840W).
Alternatively RS do one but there is no mention of resistive load:
I'd be so grateful if someone could point me in the right direction as am a bit confused!
