Shower Hot Water Options
Hi guys,
I've had an Australian 'Glind' hot water system attached to my engine. After making sure it's attached to the correct spot of my 38hp VP, and testing it out this week, I'm convinced it does not work. Today, with 2000 revs I get look warm water 'if' I have just enough water coming out out of the shower rose and no more. But on cold days like today, it's certainly not enough to have a shower.
I don't have room for a generator to heat a dedicated hw tank.
What do others use for hot water? There is a unit that works off 12v with its own 10ltr stainless steel tank. But I'm skeptical.

Re: Shower Hot Water Options
Bosch or other gas instant system no tank required.Had one on last boat wish I had one now.
However I would take a closer look at your Glind we had one for years that we used travelling in the 4x4 I thought they where virtually indestructible and worked a treat but obviously your engine needs to be hot.Not sure if yours is the same but really just like a heat exchanger.

Don't they have to be flewed to the outside for safety though?

Re: Shower Hot Water Options
Yes mine had a little chimney but I have seen them fitted externally if that's suitable.

Re: Shower Hot Water Options
Does your heater have a mixing valve to mix incoming cool water with the outflowing hot water? Mine has one because the water out would be scalding without it.

Re: Shower Hot Water Options
We have had an Excell ventless propane heater mounted on our anchor locker for about 6 years now. Works great and haven't had any safety issues with it at all. It is on a dedicated propane tank and solenoid that gets shut off when not in use. I also installed a water solenoid for the water supply to the heater which opens with the propane solenoid to keep it from trying to ignite.

Hoist a black nylon 20 lit tank on your mast on a sunny day and in one hour you have the best temp water for a shower

That's all very well for sunny days, (as I have one) but doesn't work at all if there's no sun. So I'm after something a little more regular.

Re: Shower Hot Water Options
Our hot water tank runs off either 110 volts or the engine. We have found that running the engine exactly 20 minutes gives you the perfect water temperature.
But, we also use a sun shower sometimes, too. It seems like we use a lot less water when we shower with one of those than when we use the pressurized boat system.

Shower Hot Water Options
When the hot water heater stopped working off the engine I traced it to a diverter on the engine. Good thing I bought 5 (they were cheap). I destroyed the first four trying to install them. The metal was thin but extremely brittle. It finally occurred to me to put a small grindstone on a Dremel. I carefully ground down the edges until I had a really good fit. Put it back together and it's worked fine.

Where is you propane bottle for this? Is it the same bottle you cook with?
Does it have to be flued outside?

I don't understand your post at all?
5 engines installed? 5 shower units? What did you put back together?

Our head is in the vee. The tank sits in a vented deck box directly above the anchor locker. We have a different tank for cooking which sits on a pushpit at our stern. The heater is ventless so it is not flued. It never runs long enough to be an issue. I did use some aluminum sheeting as a heat shield that it is mounted to.

That sounds promising. I had friends who sadly lost their three little girls many years ago from an unflued water heater set up in a tiny bathroom (not on a boat). I'm not sure if it sucked all the air out of the room or the burn off killed them from the lack of flue. But it's a serious warning in small spaces.
But I could put one of these on the back wall to my head, not in it and run the pipes to the inside. The LPG bottle could be put in my locker above the V too.
