Water Heater - on 35-3
I just did it on my 35-3 - and purchased the six gallon model from
Isotemp - the units are made in Sweden, and looks kind of like a bomb!
I'm not sure about the 35-2 in terms of space considerations, but the units are very, very easy to break down, and you can pull off the insulation, reducing the diameter to about 10.8". Mine's been installed about two months now, and I love it!
