Re: How Big Should My Hot Water Tank Be ?

Get rid of the tank completely and install an everhot or equivalant. Takes less space than a tank and gives you an unlimited supply of hot water. We have a 20 gallon with engine heat exchanger that we kept for free heating when running the engine as well, but the everhot we installed with our hydronic system makes it pretty redundant. JMHO.

Re: How Big Should My Hot Water Tank Be ?

Your cruising location is a factor to be considered. We are usually cruising in warm climates and most often don't bathe with heated water. We never run out of hot water with our six gallon water heater and most often don't operate the water heater.

Here is a link to one of those units - look at the price - Sure Marine Service, Inc. * Since 1972 * Marine Heating, Air Conditioning, and Galley Equipment

I would recommend the Home Depot system if you have AC power available. If not a discount Marine water heater with both electric heating coils and engine fresh water system coils. I like the "Superstor" units as the outer casing is/was plastic (the tank is stainless steel) and will not rust. Super Stor
- - Heating potable water by using the diesel engine takes an hour or more - after - the engine is up to temperature. So you are wasting a lot of diesel and running the engine unloaded if you are not moving.
- - I turn on my engine coolant to the hot water heater when underway during the last hour of operation (one hour before I expect to arrive and anchor) otherwise the water gets too hot.
- - Otherwise, I run the generator to make AC to heat the water, and do several other things at the same time like charging batteries, running bread machine, watching DVD's on our big screen monitor, and other housekeeping tasks that require AC electric.

Re: How Big Should My Hot Water Tank Be ?

I have a 5 gallon heater run off engine coolant. You're welcome to it as I've removed it (and the engine driven refer) from the boat. If you want it I'd be happy to ship it to you for the cost of freight. Anybody interested in the engine refer, make an offer. Both need to find new homes.

Re: How Big Should My Hot Water Tank Be ?

I'm not tackling that one, as I can think of too many wrong answers and none that are "right" to a cat lover.

If it's not too late train them to go in the head. Getting them to pump will be the hard part.

You've got to be freakin kidding me!!! The woman in the video is really serious . That said, I do know of a pet bobcat around these parts that was trained to use the toilet, but flush? Naw... But if you can train them to use a toilet, why can't you train them to hang their arse off the side?

Re: How Big Should My Hot Water Tank Be ?

Litter box placement is just a matter of hunting around for a corner which is pretty far away from your sleeping bunks (and guest bunks). Usually there is space underneath a nav desk or in the galley or where ever there is a bulkhead separating compartments.
- - But be sure to devise a system to hold down the litter box from moving as the boat rocks and rolls underway. The closer the litter box is to the centerline of the boat the less it will tend to want to wander about.

Re: How Big Should My Hot Water Tank Be ?

Have you considered a tank-less hot water heater? They don't take up near as much space, they are more energy efficient and you have unlimited hot water.
