What to look for in a Good RV Tankless Water Heater
So, what criterion does one use when buying a great RV tankless water heater? To start with, there are three main types of water heaters: propane powered, electricity powered and battery cell powered water heaters. That said, the following are other factors and features that should help you settle on a great tankless heater for your RV.
Water Flow Rate
Flow rates refer to the amount of hot water delivered per every single minute. And since most people use RV water heaters for shower purposes, a water heater that can deliver 2-2.5 gallons per minute is enough for an average family.
High temperature
On average, a shower demands 104-1060 F temperatures while kitchen cleaning needs may ask for much less. That said, a great water heater is one that can deliver a temperature rise of between 40 and 60 degrees F. Propane powered tankless water heaters are better at offering temperature rise than their electricity powered counterparts.
The cost of the heater and its overall quality are other crucial factors that you should pay special attention to while purchasing a tankless water heater. Finally, look for the presence of a company warranty to ensure that you are protected should some of its parts get faulty too soon.
Conclusion
The time for purchasing hot water storage tanks for RVs is long gone and people are now shifting their focus towards high quality best RV tankless water heaters in the market. These water heaters as you may have noted from the reviews above have more features and better efficiency than a standard tank inside your RV.
They save you on energy, help you enjoy more showers since they are not limited by a tank and help you regulate the temperature with which you shower as well. Some of these great water heaters are also very small to help save space in your RV. Their modern and meaningful features like automatic operation, timers and water resistance capabilities are just some of the other features that should prompt you to have one for yourself. After all, they are so affordable and vary very slightly in price with average hot water tanks.
