portable tankless water heaters

Hi, my wife and I just purchased a Cal 34 in excellent condition. Everything has been done except there is no pressure water supply, only the stock manual pump.
I am going to pressurize the system, and was going to install a 6 gallon water heater to run off the engine. The engine is a relatively new Yanmar 3 cylinder with fresh water cooling.
Space is kind of a problem and I was thinking of other options. This is primarily for my wife to have a warm shower.
I came across a propane operated(which is already safely installed on the boat) portable tankless water heater shower made by Eccotemp for camping, off the grid type work. It puts out approx. 1 ga. per min of hot water.
It sounds like a viable solution to happy wife,happy life. It would be primarily a cockpit shower but could easily reach the shower area on the boat.
I really dont want to fool around with the engine cooling system, and the average 6 gallon w/h is just one more system to maintain, and also has the potential to fail and overheat the engine.

Has anyone used a similiar system or can I get some feedback from the sailors who have more experience than me.

We live in SoCal and we are using the boat to visit the islands and marinas up and down the coast...nothing serious.

Thanks in advance for your help...It's our first boat,and I want it to be perfect.

Re: portable tankless water heaters

We are in Channel Islands. Between marriages, I lived aboard a Cal 29 in Alamitos Bay, and the showers in the marina were fine.
Yeah, I know perfectionist and boat are incongruous, but you know what I mean.
Gives me something to shoot for.
The portable shower in the cockpit(perhaps hanging the unit from the stern pulpit while showering, wouldnt be any more dangerous than a propane fired bbq hanging off the stern rail.
Anyway, I think I will pressurize only at this point, and look into solar showers, etc.
ocean is a little chilly here compared to the nice 85* in Cabo.
Thanks for the advice...I will check the archives next time.

Re: portable tankless water heaters

I have one in my house and nobody here can live without it. Never going back to a tank heater. Unlimited hot water, no variation in temperature even when toilets flush (not an issue onboard, but still), cheaper operating. Just exceeds tank heaters in every way.

Re: portable tankless water heaters

There is a ton of room in the lazarets. When you are finished with it, disconnect the propane and water supply and it becomes a harmless, innate piece of equipment.
I'm really trying to avoid messing with the good juju in my yanmar repower, it's running perfect now and I don't want to put a weak link in the cooling system.
I watched several demos on you tube last night and it's definitely a temporary set and breakdown. I wouldn't think of permanent install inside the cabin, but can easily see it hanging from the stern rail at shower time.
Whaddya think?

Re: portable tankless water heaters

Nice install! Now you've got me re-thinking last plan. Thanks for the photo...the hole in the cabin is already there for venting...couldn't be any more convenient.
Thanks,
Kevin
Who says it never rains in Socal...wet today.

Re: portable tankless water heaters

I used a portable propane tankless water heater designed for outside use that I got from camping world. I installed it on the back rail next to our life raft and under our BBQ grill. No problem with the heat next the LR or BBQ. It has been installed for over a year with no problems. Click image for larger version

Re: portable tankless water heaters

I just use one of the cheap 1 gallon garden sprayers and heat water on the stove. A gallon is enough hot water for a thorough shower even with long hair. My wife Kim (R.I.P.) had waist length hair and often had water left over in the sprayer when she was done showering. Cost $7

Re: portable tankless water heaters

I just hung the EasyTankless 101, same as above, but will do the plumbing this weekend. I plan to plumb with soft copper. It will run the whole boat including a hot washdown in the poop deck. I bought the vent pipe from the vendor which you must do because it is 90mm and that's not Home Depot available stuff (this only applies to EZ as far as I know), however, I'm going to test it unvented in the engine room and see how it goes. I'll try to post a final reply to the thread with results. Many folks swear by them and it looks to be a simple install.

Re: portable tankless water heaters

BTW - Have any of you that have installed this system found that you need a way to direct the flow of pressure in your fresh water system? Like with a manifold to keep a good flow of water going to the waterheater?

I'm going to start my plumbing this weekend. Here's a thread:

I have a "Coleman Hot Water on Demand" unit it has been terrific for seven years. Not the best pressure but has never failed to operate perfectly. http://www.imarineusa.com/images/39123.gif

Re: portable tankless water heaters

I went with the Easy Tankless 101 and it has about the same measurements as yours, but I think the weight was a fraction of that - maybe 6lbs (but I'm not sure). The unit cost 144 bucks with shipping in the U.S.
I mounted it on the rearmost bulkhead behind the engine room on the backside where there is an anchorlocker for about 1/2 of the space and just access to through hulls, empty space in the rest.
I'm running soft copper pipes to it for the plumbing.
I didn't even need to vent it I don't think, just lift up the seat at the helm and you look right down on it. I can lift up the seat when I need to use it for long periods, otherwise any CO gas will be way behind the engine.
