How to Choose a Hot Water Heater

Before choosing a hot water heater for your home or business there are three energy types to consider: electric, gas and solar. A gas water heater will require natural gas or propane. If the building is not hooked up to natural gas, a propane tank will need to be installed on the property in order to operate a gas heater. If you would like to consider a solar water heater, you will need to determine if there is sufficient sunshine and room for the equipment prior to installation.

Difficulty: Moderate

Instructions

1. Confirm the heat-generating supply you want to use is available. An electric water heater usually requires a 220-volt dedicated service. Do not choose a gas heater if gas or propane is not available.

2. Determine what size water heater you require. An average size residential home will require a 50 gallon water heater to handle normal hot water needs. A solar water heater is usually a larger unit, because it needs to circulate more through the solar panels.

3. Check the area or space where the water heater will be located. Make sure there is enough height and width space. Water heaters come in different heights. They are typically between 4 and 5 feet high. The shorter water heater is larger in diameter in order to accommodate the same number of gallons.

4. Consider the instant, on-demand water heaters. These typically do not have a tank, and they heat water instantly, as needed. They tend to be more expensive, yet save in energy usage.

5. Make sure the inlet and outlet water line fittings are compatible with the water lines feeding the water heater and returning the water to the home.
