RV Tankless Water Heater Buyer’s Guide
Have you finally decided to buy the best tankless water heater for RV reviews? Then note that you’ll have higher chances of picking the best one if you carefully look into these important factors:
Source of Power
You need to decide beforehand the specific source of power for the heater. Your choices actually include natural gas, electric, and propane. If there is only a single source of fuel in either your RV or home, then it would be best to find a heater, which such power supply.
However, for more than one option for a fuel source, weighing your choices carefully is a must. For instance, if your options are electric and gas, then take note that the former requires minimal maintenance when compared to the latter. However, the electric type also costs higher per unit in comparison to gas.
Weigh the pros and cons and make a decision based on what you think will be most beneficial for you.
Note that while a lot of tankless water heaters consume less energy when compared to the conventional ones, there are still specific units and models that are more energy-efficient. Go for a water heater, which has an Energy Star certification as such indicates that it is indeed efficient.
Flow Rate and Size
Both the flow rate and the size of a specific water heater have a say on the amount of water it can supply to users at a single time. While there are units that are ideal for use in an entire household, making it possible for it to run several applications at the same time, there are also those that are small and can only handle 0.5 gals every minute.
The smaller units, therefore, can only handle one faucet. Decide on the specific amount of hot water you need for your RV as this will help you determine the perfect size and flow rate of your water heater.
The drain valves are usually located close to the base of the heater for proper draining. If you think that you need this specific feature for your tankless heater, then ensure that you go for those made of brass, instead of plastic, as the material is more durable.
Spend time checking all the features of your options, too. Find out which one is really cost-effective, supplying you with a lot of useful features so you’ll get real value for the money you invested for it. One important feature to look for is the temperature adjustment.
It could be in the form of a simple knob or a panel composed of automated flow controls that you can use to adjust and control water temperature. It is also necessary to spend time scrutinizing safety and warranty features. Another bonus feature could be the glass lining in the tank as it can help minimize corrosion.
It would also be best to find a tankless water heater with digital displays. Such feature will definitely give you an easier time customizing operations and monitoring levels. It can also display collector and tank temperatures as well as pressure readings and other useful information.
One benefit of a good tankless heater is that it consumes less storage space. However, you still have to consider the location as well as the specific area where you intend to install and store the heater. Ensure that your chosen location gives you an easier time connecting the heater to your RV.
Aside from the factors already mentioned, it would also be best to find a tankless water heater with a simple and easy to understand design and interface. It should come with a display that you and anyone who decides to stay with you at home or in your RV can easily operate. Such will definitely save you from a lot of trouble.
The best RV tankless water heater makes for a great investment as it gives you a constant supply of hot water even if you are on the road. It also helps you save money and space while also reducing carbon footprint. However, you can’t just immediately buy the first tankless heater you see in the market.
You have to weigh all your options carefully and consider all the factors mentioned above. By comparing multiple products, finding a tankless heater, which can offer you maximum benefits is definitely possible.
