Good morning everyone.
I'm building a detached garage and we are about to lay out plumbing.
What is the best cost efficient rout to go for getting hot water out in the garage?

Small tanked unit or an electric tankless unit?

We kinda need more info on the intended use. Will there be a shower? A whole kitchen? A heated Bidet?

IMO, for a house, and especially a workshop with intermittent use, spend the money up front and get yourself a tankless that meets the capacity of your demands. The only draw back is, do you have enough power, or a gas supply to feed it?

Small 120v tank type.

Mine is only a couple of gallons, but provides enough hot water to wash my hands, fill a bucket to wash the car, and has pretty fast recovery considering that it’s on a 20 amp breaker.

Also, no maintenance unlike the tankless units which require regular flushing with vinegar to prevent calcium buildup.

Dirt cheap, too.

Won’t be taking a shower with one, though.

Our house in Italy has a bidet... I think I've seen exactly 2 this side of the pond, and one was actually a kitchen sink sprayer tee'd into the tank supply... Brrr....

Is that the one with the "full" massage feature with LED lighting, or just the pulsamatic full-flow air drying system? :lol:

Since I was about 4' from the electrical panel and have plenty of space, I went with this electric tankless unit for about $160. Needs 40amps, but I just use if for washing my hands. Doesn't get scalding hot, but good enough for washing or filling a warm bucket of water. Plus it uses no energy when not in use 99% of the time. Those small tanks under the sink, heating even a small tank of water, year after year, adds up.

Home Depot had a deal on the Atmore tankless heaters last year, so I figured it was worth trying. I got the 13kw 2.5gpm. Works great. Shop utility sink and shower .

My plans are for an undersink small tank tie it into the lights so its on when you have the lights on. No power required when you are not there.

The cost to keep the water hot is very low, do you really want it tied on a light circuit and to have to heat it up every time the lights come on, heat it from scratch? The heater should be on its own circuit, switch the outlet if you want.

You can skip the "heated bidet parts washer". All you need is a Toto Washlet Toilet Seat and it only requires a 110v outlet. I've had one of those, in the house, not the shop, for 12 years and wouldn't be without it. A heated seat with warm water for clean parts? What could be better!
