How To: Hot Water

Tankless Water Heaters



On this episode Terry and Dave tackle the new technology being used to heat your water; tankless water heaters. Tankless water heaters on the whole are not new technology, but for the first time on a large scale in the U.S. companies are starting to install them in their units. Terry says the only brand of tankless water heaters is Girard and says they had to go through some big hurdles to make sure that they met all the safety standards so RV enthusiasts don’t find themselves in hot water… or rather so they do.

Tankless water heaters weigh less than a regular water heater by about 75% because it doesn’t have the aided weight of water. Weighing less will mean saving you gas money as you haul you rig down the road. Another way a tankless water heater can save you money is because it isn’t constantly running to keep your water warm. The Professor teaches that a regular water heater is constantly keeping water warm that you may not use for hours while a tankless water heater only warms the water as you need it and can warm every drop that drips out of your faucet. Meaning you never have to worry about running out of hot water. It may seem like magic but as usual Texas Terry “The RV Professor” Cooper has all the answers about how this technology works to keep you supplied on your adventures.

Tankless water heaters don’t just save you money though, they also save you some hassle and headaches; literally. Tankless water heaters are a lot quieter than regular water heaters, which, as The Professor notes will help you to enjoy the great indoors on rainy days, as you are sleeping, or if you are just catching the game. Also tankless water heaters are less prone to any kind of sediment build up, and require less maintenance that your typical RV water heater. Terry is here to help you save money and time on this Ask the Professor!
