Iím not sure i understand why the heater that seems to be just a simple heat exchanger is $500, while the one that has a 12v heating element an is stand-alone is $400?

A few folks on this forum had successfully tested similar approach using air heating furnace like D2 with a heat exchanger to heat water. The Elgena unit has a built in 10l insulated hot water tank which is great. I have Isotemp Marine water heater which keeps hot water for 12 to 24 hours. For folks with D2 on board it will be good addition to have hot water, perhaps not as good as independent water heater but close.

2 questions:

1. Are you planning to have optional electric heating rod?
2. What is your solution to have hot water without space heating for summer times, diverter valve?

Good question, perhaps this heat exchanger is more complex, it has a 10l insulated tank so it could be a tank with heat exchanger combo.

Is there a way to heat only water with this air heater to tank set up of the Elgena boiler? I am thinking summertime use for when you only want hot water. More information on this product would be appreciated.

Something like this could be used to recirculate the heating air?

We used sprint2freedom's computer radiator/aquarium pump heat exchanger on our Webasto a few days ago. Worked like a charm.
