Factors Considered When Choosing a Tankless Water Heater for a RV
Choosing the best water heater will make your recreation vehicle feel like home. A heater that is not powerful or that breaks down easily can make your life more miserable. Outlined here below are the essential factors that owners of RVs need to consider when buying tankless water heaters:
Type of Heater
There are different recreational heaters that you can choose from your vehicle ranging from water heaters that store water in tanks and tankless water heaters. The conventional tanks have tanks that require a lot of storage space.
Most of the recreational vehicles cannot accommodate large-sized tanks because they have limited spaces. The commonly used containers have a capacity of 10-gallons and 6 gallons, but small water heaters can have 4-gallons.
Tankless heaters are compact, making them a perfect option for RVs. In addition to this, they are well-designed to provide a continuous flow of hot water. This means that you don't have to waste time waiting for the water to become warm.
Size
Tankless water heaters come in different sizes. The power of these tanks is determined by the maximum temperature rise and flow rate. The units for measuring flow rate are gallons per minute GPM.
You can determine the number of gallons needed per minute by computing your devices' total flow rate. Most of the topical faucets have an average flow rate of 1.5 GPM and 2.5 GPM for showers. A flow rate of 1.5 GM is enough for your recreational vehicle.
Individuals who use different devices like showers and faucets at the same time should go for devices with high flow rates. Once you have determined the flow rate needed, you should consider the temperature rise. A high-temperature increase is needed when the incoming water is icy.
Power Sources
Most of these devices use either electricity or gas. Choosing the best device is hard since both types have their pros and cons. Power is not available for those guys who live in RVs. In such a case, electric water heaters will be useless. Gas-powered tanks use liquid propane as fuel.
Individuals who have tankless heaters that use gas water anywhere they go. The standard size for the propane tank is 20lbs, and it is readily available.
Energy Efficiency
It is essential to check the efficiency of a water heater when purchasing one. Energy-efficient tanks have a low annual operating cost. Apart from saving cost, energy-efficient appliances are good for the environment.
You will use a small amount of energy to heat water if you have a device with a high energy factor. Gas-powered appliances have a higher energy factor as compared to elective ones. The energy factor and average cost of fuel can help you calculate the annual cost of heating water.
Venting
A gas-powered tankless water heater should have an efficient venting system. Most of the RVs' tankless heaters a designed with a direct venting system. They come with two vents; one serves as the exhaust while the other one is used for pulling air in from the environment.
The air can either go through a concentric pipe or two pipes-one for the exhaust and one for the inlet. The concentric vent has a parallel flow system. This is a single pipe separated by an insulation layer separating the hot air from the cold one.
Final Verdict
The reviews of the product discussed above can help you choose the best tankless water heater for your RV. This will significantly improve your camping experience. Owners of RVs should select appliances that meet their budget and needs.
The best appliance, in my opinion, is the Eccotemp L10 Portable Outdoor Tankless Water Heater, which is an energy-efficient appliance. This appliance is well-designed, making it a practical solution for both outdoor and indoor use. It is a powerful model with a maximum flow rate of 2.6 GPM.
It comes with a nine-feet hose that allows the user to connect it to the standard propane tank. This appliance is engineered with an automatic battery ignition system that eliminated the need for electrical connection.
It can also turn itself on when the water starts flowing. Additionally, it comes with temperature control knobs that allow the user to adjust the water temperature and temperature. Owners of RVs should invest in this powerful and budget-friendly appliance.
