Water Heaters for Boats

Best ratings

1 . QUICK Boiler B3

„My boat originally had a Nautic Boiler 16L installed; the model that has a galvanized interior. This finally failed, and after careful measurements, I determined that the 20L modern model would fit just fine in the same space. Installation was easy, and the Maestrini barb fitting sold by SVB went on easily with plenty of PTFE tape to prevent leaks. New brackets are made of thinner stainless than the one from 20 years ago, but they seem perfectly adequate for the task at hand.“

2 . SIGMAR MARINE COMPACT Water Boiler

„Replaced the quick 43 litres boiler with this 30 liter model. It was easier to mount the new one then to remove the old one. I miss some connection parts like 12" tube couplings to connect to the engine and 12" F-F couplings to connect the hot and cold water tubes. I also recommend to order the mixing valve to keep the temperature under control when the water is heated by the engine.“

3 . ISOTHERM SLIM Hot Water Boiler / 230V / 750W

„We replaced our old boiler for this one Its hot and only needs a short 10 min period to warm up and stay warm for at least half a day Easy to install and easy to connect. Also heard in engine Not cheap but a good quality for a fair price“
