I don't liike a space heater in a compartment because space heaters are hard to regulate and can cause a fire.

I use a 75w light bulb in my water heater compartment and another in my water hook up compartment. Last Nov. it went down to 11 near Pittsburgh and I had no problems.

I don't get it - you went from a regulatable space heater with tip-over protection to a non-regulated 75Watt light bulb that is more fire prone? Don't let either of those bulbs rest against anything flammable! You only get one chance...

If you turn off your hot water tank heating ( is that what you meant?) you will potentially freeze the HW tank causing Big $$ to replace just saying, Pex piping can take the pressure of freezing (fittings not so much) but the tank will split easily and is exposed to the outside air due to its need for air and drains.

I would get a space heater in there and just let it run continuously full blast. It may still not help with the temps super low, but it will be much more heat that a lightbulb will throw off...

DO NOT TURN THE WATER HEATER OFF IF IT IS FREEZING.

If the lines to the water heater freeze,, No damage

if the fittings on the end of those lines freeze,, Possible damage (The fitting may crack and leak)

IF the water heater freezes,, You may be looking at a new water heater

So unless it is a flash heater (TANKLESS), DO NOT TURN IT OFF as... well the heater/burner will attempt to maintain 120 degrees, and that is a long way from freezing,, So long as there is water in the tank keep it on, If the lines are froze and there is water in the tank, it will remain for some time (months) with normal heating.

Just turning the hot water heater off will not help, If you mean turning it off, then bypass it after you drain it then that would be fine. But what you want to remember is that most water heaters are insulated to keep the water in the tank hot so you already have some protection there. The electric space heaters are the best way to go, they have overload protection, fall or tip protection and are safer than the heat lamp.

Was camping in freezing weather & woke up to no water running.
Found that the forward furnace has a register in the wet bay BUT it's on the opposite side of the wet bay. Only took about a minute to get the lines thawed with a hair dryer. Ended up placing a 60 watt bulb in the bay under the lines. Caught it just in time.
Remember, that water heater has the heat exchanger (tube) thru the middle of it. I would think it would freeze faster If not on.

According to MIT School of engineering, hot water does not freeze faster than cold water.

I personally have been camping in 6 below zero weather. We have an atomic clock with an outdoor temp indicator with the remote transmitter in the wet bay. I have the smallest electric heater Walmart sells. IN the wet bay also. The heater has tip over protection and mechanical thermostat. I set it at almost the lowest setting on the thermostat and it keeps the temp in the wet bay at 49 degrees no matter how cold it gets outside. I am not sure why you think a light bulb would be better than this but everyone has their own ideas.

To join the clamoring crowd. Turning off your hot water heater is not a good idea. It takes heat being removed from water to produce ice. If I start out with water that is 110 degrees and I start out with water that is 50 degrees. I put both in 8 degree temps. I wonder which one is going to freeze faster. I think I know the answer to that.

Ok, I have a water leak in the wall. Will insurance or warranty cover it? What is done to repair?.......I was getting ready to travel and noticed water leaking down the outside of the RV, on the outside where the water lines are located on the inside. Has anyone experienced this?

Take a glass of tap HOT water and a glass of tap cold water and place into two different freezers and I will guarantee you that the cold water will be frozen hours before the hot water.

You got some BIG problems with your RV and keeping the water lines from freezing. Most people who stay in areas where there are single digit temps will either winterize their water lines or heavily insulate the rig against freezing temps.

It's called preventative maintenance.

This is where water on outside is leaking, note: I have the pump cut off, so the water does not have pressure on it in this photo.Click image for larger version

Where is your shower? A lot of people forget to open the shower door to heat also. If it is over the leak then you should have access to the shower turn off valve thru an outside small access door.
