How to Choose the Best Gas Water Heater

Flow rate. Before purchasing the heater for your bathroom, consider the flow rate of the device. Check how many gallons of water per minute it can provide. If you intend to use it alone or with a partner, 1.5 gallons per minute should be enough. If you have a big family of if you need the device to provide enough water for the whole house, 2-4 gallons per minute is a perfect flow rate for you.
Gas. Some gas heaters use propane, and others use natural gas to make the water hot. Natural gas has multiple advantages.

You should also consider your location before choosing the gas heater, as natural gas may not be available in your area.

However, this option is possible only in areas with a mild climate. If you live in a place with harsh winters, outdoor installation is not such a great option.
