Hot water-gctid353843

[Guest]

Can Someone please explain to me how my 1998 2355 makes hot water. Does it come from the engine or is it electric. Will I have hot water when underway or only on shore power?

Thank you.

Perhaps more info is needed.

Are we talking about a 2 way Marine WH that uses engine coolant heat AND electric strip heat from Shore Power????

Here's the scoop.

If this is a 2-way WH and is plumbed correctly for engine coolant heat, then the answer to your first question is YES. In about 30+ minutes of underway operation, you should have very warm or even hot water.

The WH coolant loop "supply" must come from ahead of the thermostat... normally a port in the intake man (no stat... no mild pressure for a supply).

The "return" will be the Stbd most port in the engine Circ Pump.

Since most of these are also electric strip heat, and if connected correctly to the boat's electrical system, the second answer regarding S/P is also yes!

While on S/P and when the breaker is ON, the strip will provide the heat.... just a home WH will do.

In this https://"http://www.baylinerownerscl... recent thread it's mentioned that a WH is not producing Hot Water. No mention of which brand or the installation.

It's then suggested that the engine plumbing may not be correct, or perhaps a thermostat is not in place.

Generally, when these are installed correctly, they work very well, and they'll retain hot water for quite some time.

If yours is not working well on engine coolant heat...., take photos of the engine coolant plumbing and post them here.

My 2003 285 came with the dual-mode water heater, but the engine loop wasn't hooked up. I hooked it up as described above, and it's been great.

My experience is I have never seen a Bayliner from the factory with the engine heating loop hooked up. The probability that yours is is very slim. This means at dock you will have hot water as it needs 110v to produce. It is a reservoir at the same time so you do have 6 gallons in store and therefor enough hot water for a days outing if used sparingly.

My 1998 2355 came with factory (dealer) installed Freshwater Cooling system (San Juan Engineering) and the water heater hooked up to the engine. It scavenged heat from the motor underway and then used AC power to heat water while at the docks.

My 1998 did not have it hooked up but I went ahead and hooked the hot water up tot he engine, it worked very well.

I hope that's a typo! :kidding

I asked Bayliner why (the heater loop to the engine was not installed) and was told that there was a possibility of getting scalded by the water which could reach 175F.

So, I hooked mine up to the engine as instructed in the Mercruiser manual and it works great. Hot water in 20 to 30 minutes of engine operation.

The water heaters are capable of being hooked up to the engine but Bayliner does not. I think he was giving you some BS answer because SeaRay, and other higher end boats come with this option already hooked up. Just one of the ways in which Bayliner saves everyone money at the end of the day.

They're hooked on most you see here in the salt. The addition of a freshwater cooling system is essential though. Those Atwood heaters have aluminum cores.

But the potential for burns is real unless you have blending faucets. It does not take long for the water in the heater to achieve the same temperature as the engine cooling water temp.

Blended properly you can take a nice loooooong hoooooot shower after a day of running
