AK...

The thing that bothers me most is exhaust fumes getting windblown back into the cockpt enclosure.
Any thoughts or perspective on that?

You're thinking that with the exhaust location, it would be possible for the exhaust to be blown back into the cabin enclosure?

From my perspective, that seems extremely unlikely.  First the exhaust gases are going to dilute just inches from the end of the exhaust pipe.  Second, a little heater like that isn't going to generate very much exhaust to start with.  Third, there is no direct line for the exhaust to come back into the cabin.  Fourth, the Arima cockpit itself leaks like a sieve.  It would be difficult to kill yourself in there even if you directly exhausted into it.  I run a Big Buddy heater in the cockpit and it has never shut down from high CO levels.

Just seems like a non-issue to me.

AK - Love the install.  Got my brain a thinking...... :beerchug:

I think ej answered my thoughts quite well...

Thank you sir!  :applause:

I have a big buddy but have never used it in the boat as I worry about the fumes AND about an explosion from an inknown propane leak.   :hoboy:
Maybe it's just me, I tend to be overly cautious when it comes to life and death.  Non-lethal things...I am MUCH less cautious about.   :facepalm:

Am I crazy or just getting old?

AK angler,
I am trying to figure out where I would put the diesel tank. 

I notice your diesel tank has the yellow rear vent opened.  I would suppose the tank has to be vented. 

I was thinking of putting the tank inside one of my seat boxes. 

On my boat where you have your tank I have my auto pilot installed. 

I am not sure but I believe there are rules on how the tank has to be installed and what ever rules there are.

I think the tank has to be able to be filled from outside the boat. 

Anybody have any information on this.

Yes, the tank needs to be vented.

I would think that putting the tank in a seat box would work fine.

There may be some, but I don't know of any specific requirements regarding the installation of a small diesel fuel tank on a boat. I took my installation queues from how the heater manufacturers recommend installing them.

I have done quit a bit of research on boat heaters since looking at AK Anglers post of his Webasto heater.

I would like to get away from propane mostly because of the moisture it causes.  Also the nature of propane.

Most, or all, of the bulk head heaters that use kerosene or diesel I have researched all experience some sort of soot problems from time to time.

I can't really find a bulk head heater that has a small foot print like the Webasto.

Besides I think forced air is preferred.

The problem is most of the information out there is coming from yachters who all have larger boats and are of a different sort.

I have found that West Marine wants $3,000 for a Webasto Air Top 2000st which is the newest version of the heater AK Angler has.

I have found several Webasto heaters that appear to be the same thing on Ebay that sell for right around $1,000.  I seen a used one on Ebay for current bid of $500.

I'm not sure if the units on Ebay are the same as the true Webasto Air Top 2000st.  I really don't want to purchase a  knock off.

I have included a link below to Webasto.  I also included a link to West Marine, and a link to Ebay.

If anybody has the inclination to take a look at the three and let me know what they think I would appreciate it.

Thanks,
Tunacious

As far as I can tell, the heater itself is the same in both the West Marine kit and the eBay kit you linked to. The accessories included with each kit are different. For instance, the WM unit has a marine through-hull exhaust fitting, exhaust drain, and more hose and vents. And, the controls are different as well. That said, I can't imagine that the additional accessories are worth $2k in additional cost.  :shrug9:

There are several on Ebay to choose from.  I just picked one.  I will have to look but maybe  some of them are more similar to West Marine.

AK Angler,

Does the unit itself get hot?  What do you think of the location I am suggesting?

I have measured up my Arima and looked at the dimensions of the Webasto AT 2000st.

I am thinking the best place to put it is inside the top shelf pictured below with the fuel tank in the bottom shelve below it.

I know the fuel tank won't be very big but it will be out of the way and easy to access.

The down fall is I will be loosing the storage.

The unit doesn't get noticeably hot.

One problem I see with putting it in the upper shelf is routing the exhaust. The exhaust comes out of the bottom of the heater, and it is hot. I wouldn't want it routed next to the fuel tank that you plan on putting in the lower shelf, even if the exhaust is insulated (which I highly recommend). If you put the heater up high, above the top shelf, it looks like you would have room to route the exhaust out the side without needing to go through the upper shelf.

By the way - these are the same issues I was wrestling with when I was installing mine. There's not an 'obvious' good spot to mount it. Like many things on boats, and boats in general, each location is a compromise. I looked at installing it in the rear, next to where I mounted the fuel tank, but the heat loss from the duct being in the cockpit was an issue. I also looked at mounting it on the port side bulkhead in the v-berth, too. That might be a spot to look at...

I have a question about venting diesel fumes out of my boat if  where to install a webasto heater.

Its 8:00 PM and dark.  I just came in from crawling around in my boat with a flash light.  I really want to install one of these webasto heaters.

I am trying to decide where to mount this heater and the fuel tank.

I have no room for the diesel tank in the back of the boat.  On one side of the boat are my batteries and on the other side is my onboard battery charger and the auto pilot.

My options are to move my batteries up front like some of you have.  With a hard top I really don't need to move the batteries for the same reasons as most of you. (to disperse the weight)

The other option is to place a small 2 gallon fuel tank on one of the shelves in the cabin area.

If I do this I am wondering if I can tie a vent hose from my yet to be figured out diesel tank into the same vent hose that my saddle tank uses.

My saddle tank has a vent hose that vents to the outside of the boat.  I would just add a T to the vent hose and vent my diesel tank into the same vent tube already there from my saddle tank.

I would not want the diesel fumes to somehow condensate and drip back into the gas tank for the boat.

What are your thoughts??    :shrug9:

Thanks
Tunacious

I wouldn't try to connect to the gas vent. When fueling, the diesel/gasoline you're pumping can fill the vent line and dump fuel into the other tank. That wouldn't be good for either system...

What kind of tank are you looking at? If you don't want to install another through-hull vent, could you run the diesel vent back to the cockpit, maybe under the gunnel?

Good idea on running the vent to the back of the boat.  I don't have a tank figured out yet.  It is going to be in one of the places you suggest because that is really the only choices.  If I put it in the v-berth on the port side, How noisy is it, in case I was wanting to sleep in there with the thing running.

Everything is noisy when I'm trying to sleep! HA!

But, seriously... both the volume and the quality of 'noise' is fairly subjective. That said, in my opinion the noise isn't harsh (basically just white noise), but the Webasto isn't exactly silent, either. In fact, your concern about noise while sleeping is why I mounted it where I did instead of inside the v-berth. But, to be totally honest, I never sleep with it running overnight - even during the winter. If I had realized that earlier, I would have mounted it in the v-berth. But, some things are learned by doing.

If you're committed to the install, you could always buy the heater and fire it up in the garage (or wherever) to see if the noise is going to be an issue for mounting in the berth.
