Hot Water Heaters | Boilers

Water heaters and boilers are residential and commercial appliances that provide a continuous supply of hot water throughout a building for conditioning or washing. The variation in names and functions of hot water heaters is attributed to their capacity to heat drinking water, usage in the a range of purposes in the domestic or industrial sphere, and their respective energy sources. Fossil fuels are commonly used for heating water, but alternative energy, backed with fossil fuels or electricity, can also be implemented instead. Electric heat pump hot water heaters are another more efficient, but more expensive, option. Hot water for the purposes of space heating is heated in a boiler.

What size water heater do I need?

Determining what size water heater is needed requires figuring out the amount of water one uses during the busiest hour, or the time of day when the most hot water usage occurs. For a general estimate, a household of 1 to 2 people requires 30-40 gallons (114-151 liters). A household of 2 to 3 people calls for 40-50 gallons (151-189 liters) and 50-60 gallons (189-227 liters) for 3 to 4 people.

How long do water heaters last?

The general lifespan of a water heater ranges from 8 to 12 years. The exact life expectancy is dependent on the quality of water and installation as well as the overall design of the unit. A water heater headed towards 10 years is typically due for a replacement.

How do you install a water heater?

For a gas water heater, disconnect the gas and water lines and detach the gas exhaust. Then, set the water heater in position. Install both the heat valves and water line connections. The last step is to attach the gas line. For an electric water heater, move it into a drain pan and install both the T&P valve and discharge pipe. After, attach the hoses and fill up the water heater by removing the aerator and turning on the water supply. Connect any wiring and check that the tank is full by turning on the faucet.
