Showering on the go

Why didn't I figure this out before?! In the past, we would turn on the engine heat near the end of the trip for the day so we would have washing up water for the galley. Anything left over and one of us might shower. But we decided, why not turn on the engine heat sooner and we could shower on route? No problem doing that during calm conditions. It works well and we each can get a shower while we are running. Using the inverter while running the admiral can use her blow dryer. It's free heat and free power.

Yes - done this many times. With five of us on the crew down from Ketchikan to Anacortes we would depart at around 7am each morning and then take it in turn to have our morning showers underway. Then there was still plenty of hot water for dishes in the evening at anchor.

We always had the recirculating engine "coolant" heating the hot water tank when the engine was running. Electricity was only for back-up when anchored or docked for an extended period. Our 20 gallon Raritan held the temperature pretty well for 24 hours, depending on usage, and the engine heated the water to 180 degrees, so needed to be careful. 20 gallons always seemed to be enough.

Further to previous answer, I guess if you have a much bigger (than 2) crew then you would run out of HOT water!!!

Our tank is 12 gallons. I typically have a very short shower. The admiral has liner hair, ergo, more water.

Yes, to the OP, you may want to check your system. Our engines heat the water in our H2O heater. So, it really is "free".

20 gallon Raritan WH with tempering valve and coolant loop heat exchanger on my boat. Almost endless hot water for 2 or 3 people.

six gallon isotherm. Heat the water every day when we run the generator. With just two of us there is enough hot water for showers and dish washing.

We have a 6 gal but the water is so hot that we use very few. We have enough everyday for shower for 2 person, dishes in the evening and following morning. We will replace the heater with a 11 gal so we have enough for 2 days. Water conservation is easy, shower head can be replaced for a low consumption one so you don't waste.

Nothing wrong with the system, just conserving water.

I didn't mean it like something was wrong with your system, just saying check to see if your already running engines provide heat without turning on the hot water heater.

Showers underway are the best, especially when there are whales and mountains and icebergs visible out the porthole!

Not really sure what it means to "turn on the engine heat." Most systems are hooked up so that the engine jacket water circulates through the water heater whenever the engine is running. There may be bypass valves for emergencies, but when would you NOT want hot water?

As for showering underway, been doing that ever since we first got a boat with a shower. Especially when motoring a long way through protected waters to an anchorage for the evening, or any time on a long inland run like the ICW. Either way, you arrive at your destination with a full tank of hot water, which cuts down on the genset run time.

That's how the Coot is plumbed. ... My sister's reaction: "you have hot water?!"

We don't seem to have hot water unless we switch on the engine heat. I seem to remember the PO confirming this. And yes, there is a by-pass valve.

This is the "plumbing" and heat exchanger for heating the hot water tank, via either the Webasto Hydronic heating system or the engine heat. The Webasto heats the water to almost scalding temperatures.

I just like how accessible the plumbing is. Mine is hard to get at. I need to replace some hydronic heating hoses and keep putting it off because of that.

JD has the choice of switching between engine heated water while underway or diesel heated water with his Webasto system while docked or at anchor. I'm guessing the switch is for a 3-way solenoid valve but it's not shown in the photo of his pristine engine room.

I'm going to be the odd man out, erring to the side of caution.
I disconnected all external plumbing from our Cummins cooling system. I have heard of too many folks that had the main diesel engine destroyed because a hose or coil blew and drained all the coolant.
To me it is not worth risking your $35,000.00 engine to heat water.
IMHO

Jim,

Beautiful Engine room. I am jealous.

I'm not sure why you would not have the engine heat always heating the water heater. Mine is plumbed to do so with no way to turn if off. But I've never needed to.
