Diesel heater installation I.

After some unsuccessful tests to heat a cabin like this one, we've decided to bite a bullet and buy the proper marine diesel heater kit Webasto Air Top 2000 STC with MultiControl.

This new MultiControl allows scheduled times, but mainly fresh air circulation during hot days.

The box with all required accessories (kit no. 9034777B), 60mm ducting and 3 outlets arrived at the Christmas present for my wife, so there is no wonder, she was very happy. Now, we can now stay on board longer when the night temperatures get cold and dry clothes during rainy days.

There will be three hot-air outlets. One in the aft berth, one in the head for clothes drying and one in the cabin.

After some thinking, investigating and getting inspirations from other boat installation, I started to laminate thick plywood panel for the heater holder in the port cockpit locker.

Then, because I had a gasoline tank there and it's fumes could cause a nice bang when the heater is running, I had to move it into the middle cockpit locker. Which means, I had to build the new shelf again.

As a glue I've used the thickened epoxy with Cabosil and microballons filler. The next step is to put over a layer of the glass to seal it and paint with the top-coat. However the winter came to visit us again these days, so I have to postpone it a little.

Next thing is to drill some holes for the ducting with 67mm hole saw.

For a better access to the ducting and installation, I've cut an additional inspection hole in the port cabin seat.

This hole is also useful for routing new wires into the DC distribution panel, which is just above the port seat.

Now I have to build a ductings cover in the aft berth. This is going to be quite a big project so that's why I'm going to split it into several posts. Stay tuned for more.
