Re: Diesel heater install

Eric Freedman


A friend of mine with an Amel just installed a Espar hydronic heater in his boat. He even put a blower in the cockpit.

The hydronic unit seems to be a much simpler installation than a forced air unit. When I had Kimberlite made it came with forced air ventilation which was easy to convert to heat. Running that duct would be much more difficult as a refit.

Did you look at a hydronic unit? It has thermostats in each cabin.

We are looking at installing a Diesel heater to our 1996 Super Maramu

Currently looking at a Wallas Spartan 4.5kw unit which has three in and out ports, we'd like to run a port to the Saloon, main cabin and forward guest cabin

Does anyone have any experience with this heater?

Has any one ran 75mm (3 inch) warm air duct through their boat? did you find any good paths or impossible paths
