Curious .......
Whats the concensus over leaving your hot water tank and water pump turned on or off when you are leaving for the day say 8 hours or more ?

More energy efficient to hold the temperature or to heat up the temperature loss over the day ?

We turn off the water pump after each use. Just a habit.

Water heater I leave off while away from the boat.

Just what we have always done. No real reason. Just what we do.

If I cannot leave my boats potable water system on, and the hot water heater on during a shore excursion, then I have a problem with my boat that needs to be fixed.

If I am leaving the boat for more than a couple days then I'll shut off the HWH, more out of habbit and energy conservation than anything else. I also shut off the potable water but I have no reason to, because if I had a leak I'd of course fix it.

I don't turn off the HWH and water pressure at home when I'm away, what makes a boat so different???

I usually turn off the water supply and water heater when away from my boat for more than a day to save energy. The PO had a water line leak while they were away and it drained the water tanks into the bilge. No major damage, but it can happen.

My home is 30 years old and I always turn off my main water valve and water heater when I leave. My neighbors on both sides have had substantial water damage when toilets have overflowed while they were gone for extended periods.

Off and off.

If something fails (known to happen) in your water lines the pump would empty your water into the boat. The hot water talk has a life span, why shorten it by leaving it on for no reason.

I never leave the boat for a period of time without turning off the dock water supply and the on board water pump along with the HWH. Dock sid water supply left on can sink your boat.

I am with Kevin. If I leave for me than a couple of days, everything gets turned off. If you are leaving for a few hours or a day, leave it on.
I would think there would be more wear and tear heating it up from cold, rather than leaving it on.

Also, I never connect my boat to the shore water supply. For those that do, I definitely recommend that it be shutoff when leaving the boat.

Shut them off when not in use is a good policy. Along the theme of water heater has a definite life span, you can increase the life span by changing the anode rod in the heater every four or five years.

If we leave for the day fishing or whatever I turn off the pump. Not that 200 gallons will sink the boat but I wouldn't want to loose all my water.
I connect to shore water when I'm at my home dock. I always turn it off at the dock even If I'm only going to be gone a couple hours.

I had a refer ice maker line break in a rental in Phoenix. It ran for a month before our gardener called to tell us water was coming out of the side of the house. It wiped out 4 rooms including the kitchen. Lesson learned.

A hot water heater and full fresh water tank is the same displacement whether it is on board, or if it has leaked into the bilge. If it has leaked into the bilge then the bilge pumps should handle it.
The point is, the amount of water in the fresh water tank and water heater will not sink the boat.

Also, this is why I made the comment regarding shutting off the shore water supply if you have it connected. A leak in the potable water system with the boat connected to shore water supply can definitely sink the boat.

Boat systems, like RV's, are no where near the quality of home systems. Homes have soldered copper pipes that can withstand high pressure. Also boats plastic systems are exposed to freezing temperatures in the winter.
They just are not as high quality as homes.

We leave the boat the water pressure is off and so is the water heater. No sense in paying for electric for something I'm not using. Besides, once we get to the ancorage, the port engine has done a fine job of heating the tank to 165F.

It's funny how I will do things out of habit but only when someone asks a question do I then actually think about why I did things that way :)

I started with a travel trailer before getting the cruiser, so I guess those habits just carried over. Since I only hooked up the travel trailer to power and water or the boat to a power supply (no hookup to water, only holding tank) when I was actually using it, once everything was hooked up I simply kept everything turned on.

Once I get the boat back into the slip and I'm ready to leave, I do shut everything down except the battery charger and refrigerator. No point in paying to heat heating water when I'm not there. I do shut the water pump off for one reason - if for whatever reason the tank does run dry the pump would run non-stop. Now maybe these pumps can operate dry and not get damaged? I don't know, but since the switch is right next to the main power panel, it's just part of my routine to shut everything down when I'm done using the boat.

There is only one consideration on a travel trailer water heater that doesn't carry over to my boats water heater - propane gas can be used to heat the water (faster than electric heating element). In that situation I would NOT keep the gas heater on if I was going to be away for an extended period of time. Mainly to keep the system from burning out. Should the tank run dry for whatever reason, you are not supposed to run the gas heating element with an empty water tank (it could destroy the heating element)

I used my shower for the first time Friday afternoon and apparently forgot to turn off the water supply to the shower head after showering, I only depressed the button that turns the shower head off. And then I forgot to turn off the water pump when I left the boat.
So Friday night when I came back there was a few inches of water in the shower pan, nothing the shower sump didn't make quick work of, but would of been bad if I had been gone for weeks.

I live aboard our boat and leave them on (they are on as I write this and I am at work). If I am going to be away for multiple days, then I turn off most everything on the boat (except for the refrigerator). This is for the power savings and no other reason.

If I left them on, I wouldn't lose any sleep. If it is only a few days, I leave them on. Off is my habitual selection.

1. Shore water tap never more than 50% open at valve to guard water pressure.
2. Shore water off and pressure bled out when departing for more than a day. The reason is that the pressure regulators are poor quality products and I have replaced 3X. Also guest shower once dropped for days and could have overflowed the shower
pan (that pump is apaniah pump not auto like the master sump).
3. Always shut down HWHs when gone for more than one day.
4. Always shut Vaccuflush pumps when away for more than one day.
5. Always shut down fresh water pressure pump.

During very cold temperatures (below 30 F for example) the water heater might be left on or on a timer as a means of freeze protection in addition to the small electric heater in the main cabin.

We do not have metered electricity at our slips, the 30 amp service is included in the rent. It is expected for the owners to have some sort of 24 hour heat set to around 50 F for protection against mold and mildew especially during the winter months.

Just a FYI. This will not guard against water pressure even if you close it 99.9% of the way. You will only reduce the volume of water that can flow through the valve which has no bearing on pressure.
