9-best-RV-water-heater

An RV water heater is a must-have for any serious camper. Not only does it provide a steady supply of hot water, but it also helps to keep the RV interior warm and comfortable.

There are two different types of RV water heaters: gas and electric. Gas RV water heaters are powered by propane, making them ideal for use in remote locations where there is no electrical hookup.

Electric RV water heaters are powered by either shore power or a generator, making them more convenient to use but also more expensive to operate.

No matter which type of RV water heater you choose, it’s important to make sure that it is properly vented to prevent carbon monoxide build-up.

In addition, it’s a good idea to install a water filter to remove impurities from the water supply. With a little bit of care, an RV water heater can provide years of trouble-free service. For a small house, a heater with 40-60 GPM would work finely.

RV water heaters are also very efficient, meaning that they use less energy and resources than traditional water heaters.

This makes them an excellent choice for those who are looking to save money and be more environmentally friendly.

In addition, RV water heaters are very durable and long-lasting, making them a wise investment for any RV owner.

So if you’re looking for a reliable and efficient way to keep your RV supplied with hot water, an RV water heater is the way to go.

You can also get an RV water heater that would work for your bathroom or kitchen tasks. Yes, it would heat 6-10 GPM.
