Adding booster water heater
Posted on 7/16/19 at 12:20 pm

My kitchen is a long way from my water heater (Rheem tankless) and it takes several minutes for hot water to get to the faucet. I am considering adding a booster water heater but wondered if anyone else had tried and liked\disliked it.
Power and location is not a problem, I have a pantry on the other side of the sink so I can make it work easy. Here is what I am looking at:

We have a similar problem. Recently replaced two tanked hot water heaters with one tankless style and the cost savings has been pretty amazing. Downside is the travel time, over a minute for hot water in the kitchen sink.
Just not sure if it is worth it versus just letting the water run.

I have this on one of my tank water heaters in the attic. Works well. LINK
I need to install one on the other water heater. I was fortunate to have a nearby electrical outlet in the attic

Just get a recirculating pump

With a recirculating pump would the tankless water heater never turn off? Wouldnt I lose the cost efficiency of it?

No, they recirculate on demand or on a schedule, not constantly. Yes that can bring its own challenges and may not work for all scenarios. Some of the options I'm aware of are:
- button or switch at the faucet
- motion activated switch at the faucet
- wifi activated
- scheduled recirculation
You do have to have a return line run, or a crossover utilizing the cold water line.
I don't have first-hand experience with recirc, but looked into it a bunch this year before buying a tankless water heater.

Maybe I’m missing something here, but how does it work without extra pipelines?

Just get a recirculating pump
When we moved in (new construction) we were having the same issue with hot water in the kitchen. We have 3 bathrooms upstairs and one on the main level, and the kitchen sink is at the end of the circuit - took probably a good three minutes to get hot water there.
Plumber came out and the recirculating pump on the unit had been turned off. He switched it on and we get hot water at the kitchen sink in a matter of seconds.
