The appearance of a commercial water heater and a residential water heater may seem very similar, but they have a few key differences. The first distinction is the size of the water heating units. Commercial water heaters are designed for commercial spaces like restaurants, businesses, and office spaces, which means they have a lot of water to keep hot. They have to be able to disperse many more gallons of hot water throughout a commercial space’s layout than a home requires. In fact, a large residential water heater can handle up to 100 gallons of water, but a commercial system can handle 250 gallons. The next key difference between a commercial water heater and a residential water heater is that a commercial water heater is designed to require as little repair and maintenance as possible. Commercial water heaters are made of more durable and tougher materials, which means less downtime for these hardworking units and less revenue loss for business owners who rely on having hot water consistently.
