Home made diy heating will it work

Brexit exchange rate!

 

I enjoy how random this has completely gone. I'm just waiting on the parts to arrive. I also bought another 200w element. To halve the warm up time. The water temp will be controlled but a adjustable thermostat

 

Check what wattage your kettle is

 

Where are you going to find 33 amps to drive your elements?

 

I have 110ah battery plus 230w solar panel. Plus i dont expect to run the elements continuously I'll set the thermostat to turn the elements off at 70° and back on again at 50° so it all depends on the rate of heat loss from the inside of the van
