If you are living off the grid, you know how important it is to have a reliable and efficient source of hot water. You also know how challenging it can be to find the right water heater that suits your needs and budget. That’s why I decided to share my experience of installing a tankless water heater for my off grid cabin. 

I live in a small cabin in the woods, far away from the grid. I love the simplicity and freedom of my lifestyle, but I also enjoy some modern comforts, like hot water. For a long time, I used a solar shower bag to heat water for washing dishes and bathing, but it was not very convenient or reliable. Sometimes, the sun was not strong enough to heat the water, or the bag would leak or burst. Other times, the water would be too hot or too cold, or run out before I finished.

I decided to look for a better solution, and I came across tankless water heaters. These are devices that heat water on demand, without storing it in a tank. They use propane or natural gas as fuel, and they are very efficient and compact. They can provide endless hot water at a consistent temperature, and they can be installed indoors or outdoors.

Why I Chose a Tankless Water Heater

A tankless water heater, also known as an on-demand water heater, is a device that heats water only when you need it. It does not store hot water in a tank, but instead uses a gas burner or an electric element to heat the water as it flows through the unit. This means that you can have unlimited hot water without wasting energy or space. Some systems like the one below can service a large off grid home and include expansion tanks to prevent water knocking and allow for very precise flow control.
