Hello , i have a cascade 2 water heater from a caravan with the conrol switch for the glow plug and the water pump from a caravan too which is the submursable pump kind .

Im looking to put the heater in the van with the pump with a hot and cold in the shower and a hot and cold in gthe kitchen area .

My question is how and where do i wire it all up ?

on the cold side  on the pump there would be a live and a earth to get to work so if i put the 2 cold micro switches on the cold side going to the live on the pump and earth the others ?  so the live wires would be in parellel ...

What about the hot wires where do these go in parelell to the water heater ?

Is there a wire that goes from the waterpump to the heater  or is the a built in pump on the water heater ?

I know bits of it but not 100% sure on things . Oh and i have all the bits in a complete caravan but the electrics are a bit of a nightmare been adapted over the 21 years of its life . But it all works .

Cheers , matt
