Has anyone with a C30 run a webasto outlet to the head? The rest of the boat stays toasty while winter cruising but the head is a real shock when you go in there on a cold winter day and need to do your business. 🙂 I've thought of running a vent line to the head, but not sure how the existing run is split between the salon and forward stateroom, or the best path to run the ducting through or where to drill for the vent. Thoughts? Anyone done this already?
 
Agreed on the need! I thought about it on our C30 but couldn't come up with a good plan.

The heater is under the floor on the port side, under the oven. There is one duct run that basically goes straight to the stateroom on the port side, with a short branch to the salon outlet under the microwave. I couldn't figure out an easy way to get that across to the starboard side for the head. Sorry I don't have more ideas!

We ended putting a small ceramic "desk" space heater in the head but that only helps when shore power is available.
 
I’m thinking of repurposing the branch that feeds the outlet in the cockpit which I will never ever use. Need to investigate how it runs and maybe add a coupler and extra vent tubing… a project for one of these none boating winter days. 🙂
 
Not a C30 but I added a heat duct and outlet to the head on our R31. Probably the best mod I did to our boat. Especially since we like to do winter boating . On the r31 access to get to the main heat duct to the vberth is by removing the panel at the foot of the mid berth. From there everything is easy to get to. I purchased y connector, ducting and vent outlet from Suremarine in Seattle.

Thanks I’m going to look into it!
 
Mike&Sarah,

That’s a really interesting modification. We do a lot of winter boating too. I’ve crawled into that area behind the panel in the mid berth, as well as into the area of the heater and the duct that runs from it to the main berth (accessible if you pull the refrigerator). I can see how a run to the head can work. Where did you drill into the bathroom for the vent? Somewhere on the shower wall? Did you use one of the 90m/60mm Y branches (I think those are the dimensions I’ve seen before — I’m working off memory here)? Any other advice or details on how you routed things or parts you used?

Thanks for your post!

Gini,
I used 90 wye down to 60 tee into the main line. After looking at my pictures I see I actually installed the wye right near the Webasto unit which means removing the fridge. Then routed the 60mm hose to the head. I drilled through under the sink shelf. Ran the hose under the bottom side of the shelf that is under the sink..I drilled the outlet hole next to the toilet. See the pic in my photo album. It’s the only pic I have there but I can send you more pics if you like.

I hope this is as straight forward on my C30... Need to carve out an afternoon here soon to do some investigation. Pulling things apart is never my favorite thing to do. 🙂
 
Mike, that photo is a help, thanks. I don't think I need any others. But I do have a couple of additional questions.

First, it looks like you used some of that high density foam insulation that Suremarine stocks. I've used some and found it challenging to slide on. Do you have a trick for doing it?

Second, I'm curious about how your ducting routes/branches compare to mine. On mine, there already is a 90 to 60mm wye right off the heater. The 60mm duct off the wye runs aft to vent next to the oven. The 90mm duct runs straight back for a few feet then does a big U-turn and runs forward to the area under the helm, where there is another 90 to 60mm wye. The 90mm duct off that wye runs to the vet in the master berth. The 60mm goes to the vent in the starboard side of the center aisle (located in the side of the step up to the helm).

Not sure how clear that explanation is. But I'm wondering if the wye you added was a third one, or whether you started out with only one rather than two, as in my system. I might have to approach placement of another wye in my system a bit differently given that I already have one right off the heater and a second one another 5 ft or so later in the duct. But that's half the fun of a project like this -- figuring it all out!

PS. For anyone interested, in addition to SureMarine, another source for parts is Heatso. I've had a good experience ordering from both. Here's a link to their air ducting accessories: https://www.heatso.com/air-ducting-accessories-1/.

[One more note after my original post]. I've also ordered from Butlertechnik, in England. Surprisingly cost effective and efficient shipping despite that. They have a particularly good library of technical manuals and documentation -- better than some of the manufacturers' own websites! https://www.butlertechnik.com/technical_library
 
Gini,
I used the Webasto high temp ducting that sure marine had. It is not insulated but it comes in a short length and you stretch it out. It actually went on to the fittings just fine. If you have trouble you can make a couple 1/2 inch cuts lengthwise in the duct at the end you are installing a fitting. Fold back the duct slightly and slip over the fitting.

I put the 90 to 60 wye in line just forward of the bow end of the Webasto heater. That is a couple feet after the big bend in the 90 mm you mentioned. If I remember correctly I put the wye in just before the wye you mentioned that goes to the cabin outlet by the helm.

Yes this is the third wye. Mine had 2 originally like yours.

Have fun exploring! Projects like this help you really understand your boat. Also help know where to go if you need to do any repairs on other systems down the road.
 
Thanks for the clarification, Mike. That helps.

Some of the Cutwaters have a heater outlet into the back cockpit. I've been thinking about that possibility too. So there are multiple ways to enhance our heating system. I'm looking forward to exploring the possibilities. Your info has been a good catalyst!

I spoke to the Factory (Ralf) yesterday and they said this would be a challenging one on the C30, but worth invesgitating. The heater is located port side under the galley stove floor access panel. All of the existing heater outlets are on the port side of the boat for good reason: Stringers. Crossing the stringers with a vent hose will be challeging to get it to the head, and I have the fuel and water tanks which are also in the way. I'm going to have to remove a lot of rat fur panels in the quarter berth and investigate what is feasible, or i'm going to have to give up on this one and have a cold a**. :-D
 
I have a c-288, so probably not applicable, but the manual says all the heating ducts and the webasto heater are in the port side of the boat. But the starboard helm and the starboard windshield defrost vent both put out warm air when the heater is running. It also has a blower separate from the heater, so it can be done. I have no idea how it is routed, but maybe the factory can look to see if the c-288 solution can be used on the c30

As already mentioned that was my conclusion. But then I had this idea, which I would try if we still had the boat: get a small Jackery or other AC battery (so there is no drain on ship's batteries) and one of these or similar:

Great idea! I'm researching to see if there's an actual heated seat that will work with that toilet, I'd like it to look a bit more built in. 🙂
 
There are some under-seat attachments that are basically the same except they are less visible. Personally I would take warmth over aesthetics for winter boating.

If you find actual heated seats that would fantastic to know the supplier!
 
+100 That was a second issue I ran into, that the ones I found were for standard sized home toilets. But there could be one. Thetford/Tecma (I think) used to make a complete bidet "Toto" style head but discontinued it. I don't recall if that had a heated seat.

All of which is a good reminder about the Seattle Boat Show in a week, to see what's new!
 
Plugging in a small space heater does the job well enough for me.
