I've wanted to go tankless for some time. The "name" brands are a bit pricey and I was told that I would have to increase the size of my gas line and upgrade my circuit panel - all of which was going to cost me thousands. I shopped around any came across the Marey tankless for less than $200. It only needed a 1/2" gas line and the ignition was 2 D batteries. Installation was simple and my final cost was less than $250. If a 76 year old woman (which is what I am) can do it, anyone can!! It's been working flawlessly since I installed it. The bottom line is: I'm one very satisfied and very happy customer and give this product 5 stars - I'd give it 10 if I could :)
well so far so good, haven't really put it to the test yet, due to the house being vacant ,but have high hopes.. thanks
The unit was very easy to install. Simple instructions and videos for help. I may have spent $120 in Pex, Shark bites, and some other tools/supplies. The Unit did not kick on right away, we would have to turn a secondary faucet on to kick the unit on. Then it would heat up very nicely. Some times, the water would not get "HOT" ( above 130 degrees, roughly estimating) unless I turned the control on the unit down for the volume of water. The customer service was above par, as today I called explaining I had lost my manual and wanted to perform some maintenance. Upon inspection afer removing the cover, I noticed the 2nd igniter was broken. The service rep explained what is was and what it did, along with a possible future piece that may need replacing ( a water valve is missing a screw, it is on the bottom near the cold water intake adn hass a drip every 20 minutes or so.) and he suggested to get one of them now as well. The unit is covered under warranty still, it is 2 years old out of the 5 year warranty. Th rep also explained the 3 options for shipping and costs. for $12 I should have a part by Tuesday, but perhaps as early as Saturday ( it is December 17th and all postal services are busy) . I would love to rate this higher, but I cannot. I recommend buying the next stronger sized unit, mine is the 3.1 L ( we have 1 kitchen, 1 bath and the basin sink/laundry hook ups.)
Gave as a gift and they think it’s a good product. Would recommend to anyone who needs a waterless Hester.
It arrived in a reasonable amount of time, it was easy for my step-son (a plumber in training) to install, and so far it's working great!
Excellent
