Question: Does this shut off when you add in cold water or can you change the temp freely?
Document: Bought this unit for my cabin. It really works good. It takes about a minute for it to heat the water. It did freeze during the cold weather this year but that was might fault. It burst a copper line inside the unit but the rupture was where I could solder it. So far it has held. My unit is outside. This would not have happened if I had read the directions better. I shut the cabin down during Christmas and pulled power on everything.
Was easier to hook up then the directions made me feel. The power part that was not included is not needed unless more than one are used in some sort of chain.As far as the hot water goes if there are two bathrooms I would suggest hooking this unit up half way in between the two rooms. So there are no long runs of hot water pipe. The longer the run of hot water pipe the lower the temp must be set to have continuous hot water.
When I did that I shut the auto-freeze control inside this unit off. I believe it says that a inside heater comes on automatically to prevent freeze when the weather is below 36 degrees. If I had not cut the power I would not have had a rupture.The part if I had not been able to fix was about $300. I was lucky. The unit is a good one and easy to install.
Purchased this for our Park Model trailer, I figured the 6gpm would be more than necessary but the price was to good to pass up. Be prepared to spend an extra 150-200 dollars for the required hardware for installation. We are very pleased with this unit, it takes about 20 seconds for the hot water to reach our shower but after that we never run out. I even ran the dish washer at the same time with no problems. So overall for the price and GPM we are very pleased.
Just be sure to order the correct unit for your needs,,,,,  natural gas and propane units are quite different  and also there are inside and outside units. I was shipped a missmarked unit , ordered propane and had to return a natural gas unit, and pay return shipping from Hawaii. Mike
