## Description

Ranein Propane Gas Tankless Water Heater, Max 8.5 GPM, 190,000 BTU Indoor Instant Hot Water Heater RH19K-LPG-FU01 for Single Family Residence - desertcart.com

Review: Great water heater. Highly recommend. - Great product. It’s been 4 months or so since install and it’s working perfectly. Two showers+laundry+ 2 sinks running all at same time and keeps it at the temperature all day long. It heats up 75°F to 120°F in roughly 5-7secs. Super fast. Propane is really expensive here at Hawaii. This’ll save us a lot of money. One small thing is the installation instructions aren’t that great. And it didn’t come with the top bolt/screw thing it tells you to use to hook it on first. Just wall screws and anchor. Ended up not using it. Just bolted it to a 2x4 I installed on the wall. Much easier and more sturdy like this. Other than that installation is straight forward.
Review: Easy to replace old water heater - Product works great. Easy to install

## Features

- Fans Placed Underneath: It will be more secure in terms of safety, and no smoke backflow will occur. The blower has large power and can automatically adjust the rotating speed according to the change of external wind pressure and the change of water temperature to provide sufficient oxygen for gas combustion, ensuring full combustion and safer use. Low noise and longer service life.
- No Waiting Required: Unlike traditional tank water heaters, tankless water heaters eliminate the need for a 30-minute preheating wait time, allowing you to have unlimited hot water on demand.
- Easy to Assemble and Use: Uses standard 3/4" NPT water inlet fittings and air inlets for quick installation. Its compact size of 24.25"L x 15.08" W x 8.07"H takes up almost no space. If you have any questions about installation and operation, please do not hesitate to contact us and we will serve you wholeheartedly.
- Wide Application: 190,000 BTU high heating capacity and maximum 8.5 GPM. It is suitable for 4-6 outlet points, which can satisfy whole family.
- Note: We provide a 2-year warranty for the water heater. If you encounter any issues, please contact us. In cold weather, if the water heater is not used for a long time, the pressure relief valve needs to be opened to drain the remaining water in the water heater. Not recommended for areas over 2,000 feet.
