I have a an old Raritan 6 gallon water heater on my Seidelmann 299. I want to replace it with new heater that has a heat exchanger so I can hook it up to my Yanmar engine. Initially I looked with at the Raritan, but I also looked at some cheaper "squre models" such as Kuuma.(Defender.com)
It's half the price of the Raritan... Is the quality making up the price difference? Also, because it's a square shape instead of cylindrical, does it make it withstand less pressure? Thank you and GO VOTE.
