Re: Heating Your Boat

I think your decision on which type of heat primarily depends on how much you will use it. Here in the PNW we use ours year round (almost) so it was worth the time, effort and boat bucks to install a forced air diesel furnace (Wallas, excellent, love it). If you will use it quite a bit each year it might be worth it to go with the Dickinson diesel bulkhead mount, seems like everyone that has one raves about it. If heat is not much of a concern then maybe you can get by with something as simple as the Aladdin lamp Med suggested. Someone else mentioned the engine coolant type heaters and those work great when the engine is running under load at cruise rpm, not so good when just fast idling at anchor though.

Re: Heating Your Boat

I looked at the video, thanks.

We have the Brenner burner without the "lifting" feature; we just take the glass off, raise the wick and light it.

WADR to the video and the poster, that is NOT how we use our lantern. Having the heat that high will guarantee soot, which is exactly what one is trying to avoid. The claim that the glass is shaped that way to enable the large flame is not my experience.

We run the flame pretty low, can raise it a bit, but I would estimate that we run it only 30% of what the video shows. And get great light. And warmth.

Any pressurized mantle like the Coleman (and I have one, in my garage, of course! ) makes a lot of noise.

Mantles are questionable on boats - they tend to break when subjected to jolts.

The other type, not mentioned, are the smaller lamp wicks which are more like candles, rather than the larger wicks on the Brenner which are 3 1/4" wide and popped into the mantle in a circular position.

The other down side of making such large flames in a Brenner is that the inside of the glass becomes black, very soon.

As I mentioned earlier, lamp oil works just as well as kerosene.

Re: Heating Your Boat

Go hydronic. Easier install, one tenth the bulky ductwork to run, and the side benefit of hot water while on the hook -a BIG plus if you ask the Admiral.

I went with the Webasto TLS-17. It is a 17,000 BTU unit, and good for sailboats up to 40'. Stay away from the marine heating people. You can purchase these units from heavy equipment parts suppliers (Kenworth, Peterbilt, Case, etc.) for around $850, which is the same place the eBay guys buy them and flip for $1200. Yes, you'll need a few parts from the marine heating guys, but you'll be able to put your own package together for about $1800 -NOT the $4000 the marine guys fetch.

HERE'S the relevant link to my refit page on the subject.

It is tempting but when you look at the out of pocket expensives I'm sure just buying a heater is cheaper in the long run.

I'm not happy unless I'm complaining about something.
I'm having a very good day!

Re: Heating Your Boat

Rob,

Great ideas for sourcing. Thanks for those great ideas.

The choices between air and hydronic are basic:

Air heat is preferred due to lack of condensation. It doesn't heat water for showering or the galley. Duct runs are problematic on SOME but not all boats. For instance, our C34 skippers have found inventive ways to get heat into the saloon without any "furniture" work.

Hydronic is great for heating, zoning by shutoff valves on the "radiators" if you choose, provides hot water, too, and is usually easier to run pipes than ductwork.

Them's the choices.

Your boat, your choice.

Re: Heating Your Boat

Two good articles in the mag "Good Old Boat".
If you use any combustion source then highly recommend it is vented outside to prevent CO hazard and also reduce condenstation headaches.
We went with a bulk head diesel fireplace with a fan to circulate the air and love it. Much less maintenance than espar type heaters in our opinion.
That being said the forced air heaters are nice.
Reverse cyle is good, but wont work well once water temp is below 42 deg F.
Lots of options. Key is do a lot of research to find the solution which fits your boat your needs.

Stu,
Just to clarify, there is no condensation issue with hydronic heat.

Just the other weekend I watched my thermostat rise by 1deg/min for 15mins after I lit my lantern. That was in the cabin of my 41ft boat with 6'10" headroom. Only the main salon was being heated, but I would guess you could heat an entire 27footer or most of a 30-35footer with one.

The lanterns are a little finicky until you get used to them, and you HAVE to use K-1 grade kerosene, but once you get the hang of them they provide lots of light and quite a bit of heat. They can also be found new for <$100.

Hey Med, do you have a pic of the lantern you are using? Trying to find them and there are way too many options--thinking you have one with the lox-on mantle?
