It is installed in our basement, which is about 50 degrees. The water sitting in the unit cools down quickly. When you turn the faucet on, you get 50 degree water for quite a while. It takes the unit a few seconds to decide to start up, then quite a while to produce real hot water. Even for faucets close to the heater, it takes a long time to get hot water. Once you turn it off, 5 minutes later it's back to cold water. We waste a lot of water waiting for it to get hot.

I asked the plumber if it could be adjusted somehow; he said no.

Given the high cost of an on-demand unit, I think a basic electric hot water heater could be better for a seasonal camp. You can get one for less than $350 and install it yourself, using fittings that do not require sweating pipe. Winterizing is very simple.
Doesn't sound right to me....mine is pretty instant. The only water that may not be hot at first is water in the line between on demand unit and faucet but this is the same with any hot water heater...

I agree with Dan. I have a Rinnai condensing boiler combo with on demand heating. After replacing a 60 gal hot water tank, I see no difference in the delivery of the hot water. In fact if 2 people take a shower at the same time, the third person have cold water with the tank system. On demand is constant regardless of use.

After talking to a number of on-demand users, problems are because of faulty installations, not all plumbers have the knowledge to install.
