Tankless hot water heaters

We are in the midst of a total remodel of our farm house, 4 bedrooms, 2 full baths, dishwasher, washer. Was wondering if anyone out there has good advice on a unit to purchase. We are researching brands, but would love your thoughts. :D

We just had one installed and I think it's great. Rheem RTG74 Direct vent, natural gas. Rheem is what our plumber installes so we went with it.

We got the biggest residential unit which they say is for two to three baths.

Only drawback is that it takes longer for the hot water to arrive. Perhaps 30 seconds.

Here's some interesting reading.

One other thing to think of. If you don't want as long as a delay mentioned. If you install a recirculation pump that is triggered by a motion sensor in the bathrooms and kitchen. You will not have to wait very long for hot water.

Go with what your local supply house is going to keep in stock so if you need parts they are available. I love Rinnai and you can get them real quick and the are availiable online. most are self diagnostic. you will need 110v power and a receptical for the condensate. Find the coldest part of your winter ground water to determine your thermal rise to the temp YOU want and base YOUR systems needs on it. With your remodel you might want to invest in a hot water return system to eliminate any wait. use a small electric water heater 10 or so gallons and pipe it so the tankless unit(s) makes up the recovery volume. Insulate all hot water supply and return lines very well and secure the insulation joints and seems against atmosphere.
