Didn’t look at the double hob as the single will get us out of trouble if we have a err low Gas situation..That's some choice! We've been considering a Remoska Tria, but it seems to be currently unavailable (which doesn't instill much confidence in case of warranty validity etc.)
The main aim is to find an alternative to gas (currently use the R907 bottle either in the van or with a Camping Gas 2 ring stove outside) because of the cost, and difficulty of knowing when it's going to run out. The Vango Sizzle double hob might be an option - presumably 800w each hob?? Would using both at the same time overload your average EHU?
Also we can use the sizzle on EHU for boiling the kettle etc
