Put a propane one in the house we built almost 4 years ago. So far no problems. Not sure of the brand right now.

Most all dairies have gone to tankless when they have to replace water heaters. All have been propane. There is an unlimited supply of hot water where they couldn't get that with the old tank style. Had a friend in Canada, above Calgary, who had one and loved it. Know another guy in Vt that hates his because he said that by the time he gets the hot water he has turned off the spigot, like when he is shaving, running the blade under the water, repeat. I don't know how far away his tankless is from the bathroom. There is one company that boasts that they run the "cold water" around through a loop, so that it is never comes out of the faucet cold. I do know that the dairies often use Rinnai (sp?). There is one that is supposed to be "water activated" as in the movement of the water kicks it on so doesn't need an electric "starter" so to speak. I have been told that the electric ones are not as efficient as the propane type.
There are some websites to look them up on. Lowes Lumber used to carry one or two brands here.

I'm using propane for the house and almost went electric for the catering kitchen back when. We figured the cost of electric and saw quickly that propane was much less expensive to operate. Takagi for the house but I don't know the other brand at the moment. One thing to make sure of is there are clean outs installed. Much longer life span if you'll clean the thing once a year.

I have had a Bosch outdoor type in my attic for about 10 or 12 years. Its natural gas and has been no problem. The only thing I have done to it is clean the screen and run water through the pop valve ever so often. I love it. When I bought it the electric ones were not very good. They couldn't generate enough heat quickly. Not sure if they have improved since then.

the best hot water heater I have seen on a dairy was somewhere up in Pennsylvania years ago. The guy had a small boiler...he had it valved so that he could run hot water from the boiler through the plate cooler on the water side, during the wash cycle....he could wash all day at 145 degrees.

Newer gas tankless units have a circulating pump/tank that are a lot better and more efficient. I believe it will give 9 gals of hot water/min.

We got a small electric Bosch one off Amazon for $135. It takes 30 amps and will scald your skin. We use it for a small apartment in barn and it is under sink and close to shower. It is pretty amazing how hot it gets the water.

My parents have one and when my tank craps out I will get one. Biggest pro is the space it takes up IMO... not blowing up is good also.

I don't know of a con.

Good idea! But is that legal to wash at such a low temperature there?
