Things To Consider Before Buying The Best Propane Tankless Water Heater (Buyer’s Guide)

Almost 18% of your home’s total energy is consumed by the water heater, but a tankless water heater can reduce energy costs.

We are here providing a complete guide on propane gas tankless water heaters that you can get for your home. Just consider these things to check before selecting propane water heaters mentioned in our list.

Benefits of Natural Gas or Liquid Propane Tankless Water Heaters: Both of these water heaters work almost in the same way and are less costly than the electric water heater. These units produce a larger temperature rise per GPM as compared to electric water heaters.

Flow Rate: If you want hot water for your entire home, you’ll need to make a list of all water devices installed for water usage.

For this, you have to add the flow rate (GPM) of each faucet you want to run. The average result will resolve your problem. You can also get low-flow water fixtures to reduce further energy costs.

Temperature Rise: Knowing your groundwater temperature matters a lot to raise the temperature of water from cold to hot. Suppose the groundwater temperature of your area is 50 degrees Fahrenheit then you have to raise the water temperature to 120 degrees Fahrenheit for usage. Keep in mind that for colder groundwater more energy will be required to raise the temperature to your desired range.

Size & Frequency of Use: The size and design of a tankless water heater depending on the frequency of hot water usage.

For the small or medium-sized family, a smaller unit working for two to three fixtures will be sufficient. But for larger families, you’ll need to increase the number of fixtures.

Indoor vs. Outdoor: Indoor and outdoor both are beneficial in different ways. Outdoor tankless water heater suits better for existing homes so there will be less need to change the existing ventilation and plumbing.

While an indoor water heater seems perfect for new build or remodel, so you can fit your water heater wherever you want.
