I have a Hurricane as well and it works great. The Hurricane also has an electric option as well. I believe they have 1 or 2 1,500 watt electric elements that heat the water when you are on shore power. It would need a separate 30 amp power input I think.

I have the Hurricane with the electric option. The option consists of a small tank with two 1500 watt heating elements and yes you need a 30 amp power input.

A point of note. Two 1500 watt heating elements can not produce near as much heat as the diesel furnace. It is however completely quiet.

If it is really cold, do you find that you can turn on both the electric and the diesel furnace to very rapidly heat up the boat then turn off the diesel? A dockmate and I were talking about the possibility of adding the electric option. He is living aboard his sailboat and also has a Hurricane furnace and like me doesnít have the electric option.

It seems to me that in the PNW much of the time the electric would be plenty to keep a boat comfortable. For us, since we donít live aboard and donít spend that much time at marinas, it probably isnít worth the expense and work of adding.

The diesel heats so fast that you wouldnít notice a significant difference from running both. In my case the aquastats on the electric shut down before the ones on the diesel furnace. If my diesel couldnít keep up then maybe turning on the electric would make the difference, I have never had the diesel not keep up. If the system is cold I turn the diesel on to reach temp and then switch to electric. My electric option is only 3000 watts. This is only enough heat for the 3 bedrooms and 2 bathrooms. The rest of the boat is heated by 2 heat pumps. The heat pump in the bedroom makes to much noise. This is why we added the electric option. Keeps the bedrooms warm and itís quiet.

I would only recomend the electric option if noise is an issue or if you wanted to keep hydronic heat on while you are away from the boat.

I don't have a Webasto, and I think you put your finger on one of the reasons. I have a ITR Hurricane II and it will absolutely keep the boat warm this time of year in the PNW, without plugging in. It draws about 8 amps when running, and runs at something less than a 40% duty cycle with outside temps around 10 F.

I would second the recommendation to visit Sure Marine (right next to Fisheries Supply). I have bought several heater blowers and other parts from them. We installed the ITR Hurricane L2 hydronic system on our boat so we could live in the Baltimore harbor for six winters. Very quiet and consistent heat throughout the boat. The exhaust is ducted outside so we had no diesel smell.
We tried electric space heaters with 50amp service to the boat but we could only run 3 heaters at a time, and then juggle other electrical use. Popping the pier breaker at 10pm in 15 degree weather really sucks.
We also put plastic shrink film over all windows and two of the three doors on the boat. We used 1" x 48" Styrofoam boards (home depot cheap) behind items in lockers and upholstered cushions. We used a dehumidifier when needed.
Lastly, we used an electric mattress pad on the master bed.

Good luck.

Did one of them move? Sure Marine is/was right by the ballard lock, and Fisheries is across from Gas Light park on lk Union.

Yeah, my thought was to turn on the diesel initially to get the system up to temp quickly. Depending on the electric rates, the electric might be cheaper, no exhaust smell for the neighbors, and as you say, quieter. My dockmate with the Hurricane says that where it is located in the sailboat it is pretty loud in their cabin. In our boat, it isnít loud at all inside.

No, they haven't moved. Your locations for both are correct.

The electric option might be right for them. Doesnít sound like itís worth the effort for you. Adding the electric tank is one part, then you have to add the wire, junction box, circuit breakers, and relays so the boiler wonít turn on if the circulation pump is off.

As a liveaboard/workaboard family in Port Ludlow, WA we use a Wallas 40Dt. Runs 24/7 for 7+ months a year since 2014. Works great (we get it serviced every 18 months), very quiet (neighbors don't even know it's running), low amp draw and seems very fuel efficient (we average @1gal/24 hrs). One should be fine for a 40-foot boat.

And while I agree that talking to Sure Marine is a good idea, also visit the folks at Scan Marine as they are the only Wallas dealers.

First off, there is no substitute for forced air diesel heat. It's really civilized.


I'd get a second opinion on the existing Espar. Since you are in Seattle I second the suggestion of Sure Marine.



If it is not repairable drop in a replacement. This is somewhat more complex than replacing a light bulb. Combustion air in, exhaust out, domestic air in, domestic air out, one fuel line (no return), and the thermostat/control/power cable. Four hose clamps, a screw on fuel line, and a handful of little color-coded wires.

The numbers you received for replacement are way high.

That is a slick setup. I'm going to need to look into that for our system.

I am not a fan of espar or webasto. I like the Wallace for boats 40’ and less. If you have the room i’m a fan of the IRT Hurricane. Reason being they are so easy to trouble shoot and maintain.

Both Sure Marine and Scan Marine are trusted sources for services. For IRT Hurricane there is McPhearson Marine in Seattle.

I went through the same exercise some months ago and replaced my Eberspacher heater with a Finnish made device by Safire. It is beautifully made with a 3mm stainless steel case. Installation was straightforward and the unit works beautifully. Mine is arranged to obtain its' air feed from outside, thus providing some forced air ventilation of the cabin. I purchased mine from Mart Verheul of Amrit Techniek in Amsterdam. His service was excellent and the unit has exceeded my expectaions.

The safire units look interesting. We have the espar D8LC units and if we ever had to replace I'd like something that plugs in easily in place of the espar. If you don't mind me asking, how much was the safire unit?

The Safire looks interesting, but their largest is only 3.6 KW output (12Kbtu). Adequate for a small boat or mild climate. You could install several of them I guess.

Ah. Yeah. Less than half the D8LC

I spent a good part of last winter rebuilding our older webasto hl 32 diesel heater. Sure marine in Seattle told me to throw it away as there where no parts available and it was to old to service....well....I spent more time then I would have paid somebody to work on it but I found a rebuilt kit on ebay(shipped from England) and now have a completely rebuilt working heater that cost me under $200. for parts... you can email me if you want more information about what I learned in the process...
good luck..I probably would have bought a new heater but they are SO EXPENSIVE....
