Best Propane Tankless Water Heaters Buying Guide

Before choosing the best propane tankless water heater you should consider following options:

 

1. Energy efficiency: The first thing you should look for when choosing a propane tankless water heater is energy efficiency.

Tankless water heaters can use up to 30% less energy than conventional tank-type water heaters.

The reason why they use less energy is that they only heat water when needed, unlike tank-type water heaters that keep water heated all the time, even when not in use.

Tankless water heaters are an ideal option for homes that have a large hot water use, such as in a business or a large household.

2. Installation type: Before choosing a propane tankless water heater, you should be aware of the different types of installations and how they work.

There are three types of installations:

Point-of-use: In this type of installation, the water heater is installed in a place where the hot water will be used, such as in a bathroom or kitchen.

In this type of installation, the water heater is installed in a place where the hot water will be used, such as in a bathroom or kitchen. Indirect: In this type of installation, the water heater is installed in a place where hot water will not be used, such as in a hallway or basement.

In this type of installation, the water heater is installed in a place where hot water will not be used, such as in a hallway or basement. Hybrid: This is a combination of a point-of-use and an indirect installation.

3. Power source: Tankless water heaters can be powered by electricity, natural gas, propane, or solar energy. Based on your needs and preferences, choose the source that best meets your requirements.

4. Capacity: Tankless water heaters come in different capacities, ranging from 0.5 to 8 gallons per minute. The amount of water that a tankless water heater can provide is dependent on the GPM rating.

The GPM rating of a tankless water heater is determined by the water flow rate of the incoming supply and the water demands of the house.

When calculating the GPM rating of a tankless water heater, you should also take into account the size of the piping, the elevation of the installation, and the length of the piping run.

5. Installation complexity: Tankless water heaters are easier to install than tank-type water heaters, but they are more expensive.

The most basic type of installation of a tankless water heater is a point-of-use installation. However, for an indirect or a hybrid installation, more advanced skill and knowledge are required.
