What to Consider Before Buying a RV Tankless Water Heater

1. Comparing Cost to a Standard

Via Amazon.com

The standard water heaters have 6 or 10 gallons of and majority of the RVs have a 6-gallon water heater. If the RV has a 10-gallon tank, then it is not the standard one since it has normally been upgraded. If there are 4 people using the water heater, 6 gallons will run out right away.

If it the water heater holds 10 gallons, it takes an hour for it to heat up completely. The tankless ones will always have water.

2. Are You Always Going Out for The Weekend?

If yes, the tankless water heaters are great for campers who like to spend their weekend elsewhere and want to wash dishes easily just like being at home. It is because the reliability of these water heaters is 99% and can provide you with clean and fresh hot water. Water heaters do not cause scalding water injuries because they are safe to use and there are no leaking issues.

3. Fuel-saving

Aside from being energy efficient, they also use less fuel. It is actually environmentally friendly for the people who like are kind to the environment. The standard water heaters are always holding hot water that uses energy that costs you a lot of money. Tankless heaters do not have to heat up the entire tank, which is going to save you money.

4. Uses Natural Gas

Via Amazon.com

There is a gas burner at the tank’s bottom that has a venting chimney running through the center and all the way to the top. The byproducts of water vapor and carbon dioxide come out through the chimney and exits through the chimney or vent on the side wall. The flame is produced by a pilot light powered by gas. The natural gas models are priced higher compared to the electric ones, but they have higher efficiency.

5. Electric Water Heaters

This type of heater has large coils hanging down into the tank to heat water. The coils are like the ones fond in electric ovens. In general, the efficiency of electric water heaters is not as good as the ones that use natural gas or propane. Although, they cost less and do not need venting. If you do not require a lot of heated water, you can opt for this one.

6. Upgrades

You should know that tankless water heaters have to be upgraded to a gas line or a vent that will cost you a lot, but it will all be worth it. Aside from that, they are dependent on the pressure that has been delivered to your home so make sure that your plumbing system is good. A minimum flow rate is another thing they need to have the heat exchanger activated.

7. Size of The Systems

Remember to check the size of the opening prior to buying a new hot water heater. There are measurements that need to be checked and the opening of the sidewall might have to be larger so you would have to do adjustments.
