Can this be used as a point of use water heater for a shower that is a fair distance from a gas tankless heater?

Asked by: PickensCyclist
I am going to answer my own question. I had a gas tankless water heater installed and it was fine. The only issue was a shower that was a long distance from the water heater. It drove my wife nuts on how long it took for the hot water to arrive and the amount of water we wasted. I debated a re-circulation system but decided I would install this close to the shower instead. It works beautifully. The shower is warm shortly after turning it on and stays warm as long as it is running. I am assuming it goes off once the gas heated water gets to it but I could be wrong. I have the temperature set lower in the booster than the gas heater to make that happen.

Rated 3 out of 5 by from The supplied connectors reduce your 3/4" MNPT water heater connection's inner diameter by 45%. Th... The supplied connectors reduce your 3/4" MNPT water heater connection's inner diameter by 45%. The specification sheet on their site states the water connection as ' 3/4" NPT or push-to-connect fittings.' This is misleading. Both connections are 1/2" compression and the supplied connectors further reduce your 3/4" connection's inner diameter to 3/8". I bought 3/4" FNPT flex connectors based on their specification and pictures - wasting my time and money. Their supplied upper (output-side) 3/4" copper push-to-connect fitting has an inner diameter of 3/8". Their suipplied lower (input-side) supplied is a specialized/strengthened 3/4" FNPT to 1/2" tube fitting that is larger than 3/8" inner diameter but is smaller than 1/2" copper pipe inner diameter. This is due to it having a thick wall - probably to support the weight of this unit. The math: Typical water heaters connect with 3/4" FNPT and 3/4" copper pipe. If you use a dielectric union the inner diameter of your connection is reduced to 11/16". Their push-to-connect further reduces this to 3/8" making this a 45% reduction in inner diameter. To install this you cut out a section of your 3/4" rigid copper pipe and, using the supplied connectors, reduce your connection to far less than what you would yield for a 1/2" connection. If I use my own 1/2" connectors, I'm still reducing my 3/4" copper to the 1/2" MNPT on the device itself. I'm choosing to not call their technical support because this is a product flaw. Also, negative reviews of EcoSmart products indicate that they will somenow blame me for this issue. The best I can make of this is to get two 1/2" FNPT to 3/4" MNPT adapters. If this severely reduces my hot water flow rate I will either remove it or increase my water pressure.

Rated 4 out of 5 by from Read Installation before Buying Great product, easy to install and comes with everything you need ... 'IF' you have an electric water heater and you have space above the heater. I happen to have neither. So, I had to install a 30A breaker and run 10 gauge wire. I also had to buy connectors to gerrymander the water connection. That said, the benefit of using this with a gas water heater ... the gas heater will fire up when you turn on the water, and will continue to run even after this kicks in. With the combination of the two, I have not run out of water (as of this review, have not had numerous people trying to take showers). With an electric water heater, this shares its power supply. This diverts the power to itself when needed, and your water heater only turns back on once this is off (I assume from reading the directions and their claim of increase of up to 45%). BTW ... I also have their 6 gallon water heater. Been using it for over a year on a bathroom with a shower and sink. No complaints.

The installation parts provided just don’t work and Home Depot doesn’t stock the proper parts needed. Designers must think about real world residential installation; maybe even try it before releasing a product. Total failure! Don’t buy this unless you want a real headache!

Super easy to install just using the fittings and connectors that came with the unit. I don't understand why so many people claimed that they are of no use. Not only does the unit boost our hot water temperature, it also offers some cool eco management functions and let me know when the tank or booster is working. A big upgrade.

Rated 5 out of 5 by from A must have for families so everyone gets a hot shower First, I rated the Ease of installation a 5 only because I called my plumber to do the install, so that was very easy for me. But for someone like him who knows what they are doing, it does install rather easily. Besides the electrical connection, there is just one input (from your water heater) and one output (to your homes hot water line). The benefits are great. As a family of 2 parents and 3 children there is high demand for hot water in the mornings as everybody needs to take a shower before heading off to work and school at the same time. And it seems the last one to shower doesn't get their fair share of hot water (which is usually me most of the time.) This booster works well and has a configurable thermostat where you can set the units activation temperature in 1 degree increments and the outlet temperature. The display shows how the unit is working with a load display, GPM flow and when the unit is heating.

Rated 5 out of 5 by from satisfactory product I would first like to comment on the people that make up the eco smart company. I first was interested in a tankless hot water heater by talking to a few home owners who have them even that my current water heater works fine. Most of them had natural gas. Eco smart company builds electric tankless hot water heaters and hot water booster. When I called eco smart I talked to one of their techs. When giving him my information on the size, type, and usage of my house. He answered several questions that I had, so with that said the company have knowable customer service which is also friendly. The questions that I have for them about the ECO SMART BOOST was: Can I install on natural gas water heater they answer YES (you will need to run new electrical supply line), can it be install on the end of the water line by the shower answer YES, Can it work as a tankless water heater answer YES this one depends a lot on the temperature of incoming water for example if your water temp that is coming is only 60F you can run only 3GPM and it will keep up the water up to 120F So the best to use is for what is made for to BOOST the temperature at the water heater. Way did I call customer service is to check how friendly and how much the know about their product and they are really friendly and knowledgable about their products. The best application for this unit is if you have already electric water heater, at that point everything come in the box to get it up and running. For the people that have propane or natural gas water heater: you will have to run new electric line with designated double pole circuit breaker maximum 30 amp (1x30 double pole breaker) and 10 AWG wiring which can be spendy depending how far is your EL box. The unite itself is 8" x 12" x 4"

Rated 5 out of 5 by from Another good product from EcoSmart This SMART BOOST unit works as an adjunct to an existing hot water heater. It has an adjustable activation inlet temperature at which point when the hot water heater water temp falls below that degree the booster will heat the water to the desired preset adjustable outlet temperature. This process is supposed to increase the hot water yield by 45% . This unit is NOT for amature installers! You will need plumbing and electrical skills. EchoSmart encourages that qualified technicians familiar with all codes be hired for installation. If you feel experienced enough, the unit comes with an excellent pictured installation instructions and home owner's manual. Our unit will be installed in the basement 14” above a small hot water heater as directed. First, a wall must be built. I am a real fan of EcoSmart Green Energy Products. They produce smart well thought out products made with high quality materials.

Rated 5 out of 5 by from Small.but with a big boost In my house we were only four but my inlaws came to love with us and since there are more people, the water is hot in the morning but once everyone takes a shower the water got cold after 4 of us, didn't want to buy another boler since it's fairly new, the next option is the boost, and works great. No more cold water, it turns on whenever the boiler is out of hot water. I had someone install it he said it was easy to do but i just didn't want to do that job. Quality product overall, just awesome.
