Tankless water heater

I have had mine little over 5 years and I LOVE it!!! My husband and I installed it in 5 minutes it took us about two weeks to learn how to adjust the water flow we always had tank heaters and the water where I live just destroys water heaters takes about 5 years it's awesome to have unlimited hot water especially in the winter!!!

Loved it for 2 days

It was an easy install of the unit but after that it was a nightmare. Next to impossible to find the correct venting to bring to code. I called or visited literally a dozen places locally & couldn't source all the proper parts & could not reach Marey customer service for months. When they finally contacted me back they told me to just order it from Home Depot who didn't have all the parts in stock on their website. When I finally had it all installed it worked for 2 days then sprung a leak. I tried for 2 mths to contact customer service and only got a call back after threatening to write a bad review after many emails & calls. The customer service was extremely rude & unprofessional. Based on the 2 showers I was able to take i liked the unit but not worth the extreme hassles. Perhaps I just had bad luck, but buyer beware!

I needed help with hooking up the right size gasline. If you don't it won't heat enough. I received the info I needed, and now it works great. Is used in 1 shower about 30 feet from heater.
