MAREY GA16LPDP Indoor Propane Gas Tankless Water Heater can provide up to 4.3 Gal. per minute for a perfect shower at 115°F output water temperature. You can see your output water temperature trough a digital panel, making easy to adjust the water and gas flow to your desired output temperature. It is also called water heater on demand, because it heats water only when needed, saving energy. It is designed in the US and it's perfect  to supply endless hot water for up to 3 or 4 points of use simultaneously (for a variety of residential hot-water applications). Its compact design saves space and is easy to install: you will only need 2-D cell battery for the ignition and a venting (not included in the box). MAREY has been on the water heating business since 1955, bringing tradition and innovation together.

  • We installed this in our guest cottage. It is on the outside bathroom wall inside a little vented enclosure. An extension hose goes 10' away to another little shelter for a 40lb. propane tank (a smaller tank works, too). It provides hot water to the tub, shower, bathroom sink, kitchen sink and dishwasher, and the regular sized washing machine. Normally 2 people are using it. The hot water arrives fairly fast, and it stays hot as long as needed. The flow and pressure are fine. Easy to adjust the water temp. It took a professional about an hour to install it. The dishes and clothes get clean, and the bath is plenty warm. We have had it for 3 weeks so far, and it is great!

    It worked first time and every time. i turned the water off and since it warmed back up, i turned the water back on weeks later and when it passed thru your water heater it fired right up just as though it was last used the day before.
