BUYING GUIDE: Propane water heater for an off-grid cabin

buying guide

Water heater requirements for an off-grid cabin can be slightly different than that of a typical home with all municipal services. For instance, most cabins either have no electricity or a minimal supply of it. The water pressure is usually also lower. So regular water heaters can not operate in such conditions. 

All of the models mentioned above are suitable for your wilderness living. Apart from that, this guide below should help you with understanding what to look for when shopping for a water heater.

Check out the affordable non-condensing tankless water heaters.

Tank or Tankless

Conventional tank water heaters have been around for a long time now and have gone through intense improvements. These are well-insulated water tanks that either boast a heating element or a burner to heat the water. 

It burns energy to keep the water hot at a set temperature 24/7. Tank water heaters come in sizes like 30/40/50/60/100 gallons and are bulkier and large. 

Tankless water heater only heats water when needed. When a hot water tap is opened, the water flows to the activation switch which activates the burner and heats the water. Due to this feature of only heating water when needed, the tankless units are also called on-demand water heaters. These are very small in size and compact. 

Regardless of extensive improvement, tank water heaters are still no more efficient than 0.62 factor and these are ideal if you need a lot of hot water in a short period of time. 

Tankless water heaters are more efficient and at least 0.82 factor. But these are usually more expensive than tank models. 

Temperature rise

It is an important feature but applies only to tankless water heaters. Temperature rise is how much you want to raise the temperature of your groundwater.

Say, for example, your cabin is in the northern region with a water temperature of 57°F and you want hot water to be 105°F for the shower then, 

105-57 = 48°F 

In this case, the temperature rise is 48°F. That’s how temperature rise is calculated. 

Size

It is used to determine how much hot water you can use at a time and if that water heater can provide you with that sufficiently. It’s not about the physical size of the heater. 

Sizing here is different for both tank and tankless. The term with tank water heaters is first-hour rating while with tankless it’s a gallon per minute. 

First-hour rating FHR

It is used to size tank water heaters. The first-hour rating is how much water a tank water heater can heat in an hour. You will want to size a tank water heater based on how many people in your family will be taking back-to-back showers.

Gallon per minute GPM

It’s a measure used with tankless water heaters. GPM is how much hot water a tankless water heater can heat per minute in gallons. GPM depends on temperature and it drops with an increase in temperature rise. Refer to the tankless water heater sizing guide here for more info.

Extra features

There are a few extra features that you can always look for. For instance, if you live in freezing Alaska then you will want to make sure that your water heater has that anti-freezing protection.
