Then run your cold water supply through a recirculating tank that doesn't cost $400 a year to heat.

I like to read stuff like that... catch a bunch

How interesting.

Wait. What does that mean? What does a recirculating tank do?

Go with gas over electric. Electric will have a COP of 1 whereas gas will vary between 2.5 to 4. That is if you are getting one

Solution- fill a tank with water.

Same thing a water heater does except it doesn't heat. Holds water in-line for use and storage but you use it so it doesn't get nasty.

I want one of those.

I never thought about this, but an inground swimming pool would work great for that purpose. The only challenge is that my yard is not much bigger than most inground swimming pools.

Buy a waterheater, plumb into cold water line and cut the power cord off.

A couple more things I learned on my project. I removed my furnace and old crappy stove from my trailer and had messed up plumbing. Thought it was going to be an expensive fix as I'm not a plumber and the fear of rerouting and plugging open gas lines. Decided to just bring my propane tank inside. I removed the line from the front of the trailer along with the regulator and they fit right on to the tankless water heater. Screw the open lines. On the plumbing side I discovered the shark bite water fittings and pex tubing. Wow, that shit almost makes plumbing fun. You can **** up and just use that tool remove the fitting and re do the shit quick and easy.

That's brilliant.

I have 3 of them in a place back east and I like them, but I'm quick in/out shower, don't use dishwasher etc. If you have kids and all, you'll hate them.

I have a friend who owns his own plumbing company. He says you want to stay away from electric on demand water heaters. If you go with gas, you should be happy.

Do a Google search of electric vs. natural gas.

Propane is actually cheaper to operate than natural gas.

But more dangerous
