No thread yet on Mahe - Heating
, so it's time to start one.
Up on westcoast Norway
, were both winter and summer occur every winter and summer, and we rarely see temperatures above 20C, good heating
We bought our boat in 2010 without any heating installed, due to what I thought was very expensive options from FP, and I planned to do it all myself. In retrospect, I'm not so sure the savings paid for all the hours spent...
In Port hull
I installed a 4kW Eberspacher diesel
air heater. Burner in port engine
room, air sent forward in a 75mm pipe running through the styrofoam floating chamber (sealed, of course), and further on through the locker bottom, and stairway. Valved outlets in port aft and front cabins, open outlet in port stairway. Control/thermostat on Nav station instrument panel.
has a 3kW diesel
waterheater, also Eberspacher - see sketch. Burner and flowpump in stb engine
room, along with a new Isotemp 40L waterboiler with twin coil and 220V el.heater. Hot water
is sent forward in 19mm hoses through the tunnel under the fueltank/fridge.
Heat is delivered from a defroster placed under the fridge with air outlets in port stairway and aft cabin
, a toweldryer in the bathroom, and a 1 kW radiator in the port gangway
. In addition theres a 150W 220V drying shelf on top of the radiator. Control/thermostat on the wall over the locker, and expansion tank placed up under deck
just above the windlass
In general we are very pleased with the solution.
Air heater supplies heat quickly, but noisy. The the water
heater system is more slow, but silent, comfortable and flexible. The stb gangway
is now our drying station for damp clothes and shoes, very much appreciated by the crew.
The twin coil/220V boiler allows us to produce both hot water and heating from either shorepower, the Stb engine or from the dieselburner, without mixing engine coolant
with the heating water circuit - important to avoid engine failure.
Pictures will follow.
