The one observation I have heard about Webasto is that the cycling of the thermostat at night consumes a lot of power as each time it starts the burner it goes through the ignition routine which consumes quite a few amps. The Wallas on the other hand doesn't cycle the burner on and off from my understanding. I am looking at both. I am not a big fan of exhausting out through the roof due to a possible conflict with the dinghy.

Hi,
I'm going to go with the Airtronic D-2 heater which are available from a number of places, I have just bought one from Interstate Power Systems 8200 North Fairmont Street Davenport, Iowa 563 388 9988 Nick is the contact. Current price was $975 plus 15 dollars for shipping. The Wallas folks have gotten a lot of bad press and in my opinion rudely expensive. My butane stove is fast and cheap. The Airtronic D-2 seems like it will fit my needs for cabin heat.

Tom Brady in the post above hits on an important consideration when choosing a heater.
Some of these units, because of their design characteristics, have to be fully "ON" or "OFF". They cannot be turned up or down, varying their heat output, such as being able to put out at a constant rate anywhere from 3000 to 9000 btus.
To regulate their output, they therefore have to cycle on and off, using a thermostat to do so. This start-up/shut off cycling is not only hard on the unit itself, but can drive some would-be sleepers batty!
The Webasto, Espar, and Toyotomi heaters, among others, fit into this category. They're excellent units for constant output on a school bus, big truck, or whatever, but for a small boat, particularly in moderate climates, can be overpowering, and can cycle themselves and the boat owner to death.
And at $2000-$3000, they can be an expensive mistake.
There are numerous threads where we've discussed all of these heaters, fuel sources, and safety issues before.
With this large of an investment, and all the necessary cabin modifications to accommodate the unit, it would be worth reading them all.... and taking notes!

After the electrical projects are complete, I would like to tackle the outboard water option as well. There are many units that could work and I only need to figure a way to cleanly tap into the output water on my Honda 90s.

as an option you might check out the dickinson newport propane p9000 fireplace. it's worked well, burns clean, quick on and off, has built in dc fan. www.boatownersworld.com/dickinsonmarine ... places.htm
on sale for $670. if interested i have a picture of this unit installed, visit my album.

I really like that Dickerson... do you see the flames when it is running? ..kinda like having a fireplace in the boat... I like it !
I have a Dickerson propane stove in my boat...and it is perfect...
I bought one of those transparent one and a half gallon propane tanks and am planning on mounting it in the lazerete...I will have to modify the bottom of the lazerete and build a new fiberglass bottom in it...but that is not all that hard... and it will give me the volume of propane I need for week long trips..

Warren,
We have a standard butane stove that came with the boat. I will probably get some sort of small barbie type thing for the cockpit. I'm trying to keep things simple. I carry a generator so we use a electric perkalator for coffee and hot water which is quick and no fumes to deal with. I carry a small electric heater for use before bed and the mornings currently. I have the generator plugged into the shore power and just use the outlets that are in the boat. I liked the compactness of an Airtronic D2 as it will go under the sink area. This way we should not have any burn victims if the grand children should be around. If I had not read so much - about the Wallas I might have sprung for one of them. This way instead of a Wallas I can have a heater and radar for 3k instead of just a Wallas that I would be second guessing all the time.

The Wallas D-30 units can be fitted with an electronic control panel which gives you (amongst other things) two options:-
1. You can set the cabin temperature in which case it varies output to suit.(Not sure if it cycles Off/On)
2. You can set the burn level. For nightime use we have found that you set it to min with a window cracked and that is perfect as you have minimum noise and it is constant.
Expensive... YES
Temperamental... Not so much as the stovetop units. It seems that all of them have to go back to ScanMarine and be argued about for a bit. After that they usually work.

The hydraunic heaters work fine, but you have to have a boiler system. The boiler systems are complex and expensive. I don't see an outboard of any size as being a good heat source for these hydraunic heaters. The lines in the outboard are small, and the water pumps are set up to push the water only over relitatively short distances.
We had a hydraunic neater, similar to the Heater Craft unit, that Dave pictured, and it worked great--with a 45,000 BTU boiler--and both radiant copper pipes and 4 of these small heaters with fans, in a much larger boat. The boiler unit sounded like a jet plane when it fired up (air compressor to atomize the fuel, forced draft on the buner and exhaust, as well as circulating water pump.). I don't see this as being practical in a 16 to 25 foot boat. The hot air units are far simpler. With an inboard engine, the "red dot" like car heaters work fine, and you can heat the boat well--again, not sure that an outboard can be set up to accomidate that easily.

I can recommend the Airtronic d-2 by Espar. It has worked flawlessly since last spring when we put it in. We ran it for nearly two weeks straight on our Discovery Coast trip as well as many weekends with no problems with function or noise keeping us awake at night. It has plenty of heat for a 22 and would have no problem heating a 25. We only wish this would have been a factory option. If you are seriously considering it all I can say is we would do it again absolutely.

Karl is that heater thermostatically controlled like Barry's? I know we will be looking for an upgrade once we get serious about cruising...Meredith DOES NOT enjoy beind cold and being toasty and warm would make it easier to convince her summer isn't the ONLY cruising season up here.

Hey Mark,
Our kit came with what's called a mini controller. It works like a thermostat. You choose a setting and the heater maintains that setting. The heater does cycle between outputs to maintain the setting. It really heats our 22 very well. Hope that helps.
