Gas and electric water heaters each have numerous advantages and disadvantages, but any comparison is complicated by additional myriad factors. If environmental sustainability is key for you, an electric water heater is the best option as electric units are much more efficient and don’t directly depend on fossil fuels to operate. Efficiency ratings are a measure of how efficient water heaters actually heat water.
When it comes to water or any type of liquid measurement, GPM refers to the gallons per minute. It measures exactly how much water moves through your appliance and may also be referred to as the flow rate. Certain appliances, like showers and washing machines, for example, require more water. But for the average household, the water heater should have a flow rate of about 9 gallons per minute.

How to Determine Which Electric Tankless Water Heater Is Best for You
Combination hot water heaters use the Annual Fuel Utilization Efficiency rating, which expresses the energy efficiency as a percentage and is the rating standard used for boilers. Indirect-fired heaters use a boiler that’s separate from the storage tank. They use heat transfer coils to transfer the heat from a separate boiler, typically the boiler used for the home’s central heating, to the water in the storage tank. Depending on the distance between the water tank and the boiler, they may be less energy-efficient. However, they require less maintenance since they don’t have a burner that can experience mechanical defects, or gas and ventilation lines that need to be periodically serviced. They also can be potentially more energy-efficient than direct-fired heaters since they passively utilize the heat generated from a boiler or furnace already running to heat your home.
Whether you choose a point-of-use heater or a whole house heater, choosing a size is the same process. Normal maximum water flow needs, the number of water fixtures affected and temperature rise required will all need careful calculation.

The valves can be used with standard garden hoses and made from brass or polyvinyl chloride .
