Water Heater Types

Commercial water heater types range from storage tank water heaters to tankless or on-demand water heaters, and water heaters pumps. Typically fueled by oil, natural gas, electricity, or solar energy, commercial water heaters are also referred to as gas water heaters, solar water heaters, and electric water heaters. The green revolution has taken the commercial water heaters market by storm, as manufacturers offer high efficiency water heating systems which save on commercial fuel costs, but also save on carbon dioxide emissions.

Commercial electric water heaters peak with energy efficiency of up to 98%, while commercial gas water heaters energy efficiency range from 80%-95%. Even though electric water heaters are more energy efficient, it might cost less to operate commercial gas water heaters, since fossil fuels rate less than electricity.

The greatest energy efficient potential lies in the water heater type. With a commercial storage water heater, you typically expect to use approximately 70% of the water stored in tank, while you pay to maintain the entire storage tank full of a set water temperature, increasing commercial energy costs. For best energy efficiency, storage water heaters must be fully insulated to minimize heat loss. Commercial Tank-less water heaters may provide a more energy efficient alternative than conventional storage water heaters, precisely because they don't have a storage tank, rather they provide hot water instantaneously. As hot water tap is turned on, cold water travels into the unit, to be heated either by a gas burner or electricity. Commercial premises in warm climates, may install a solar water heater to save on fuel costs, yet solar heating systems may still require electricity to pump warm water throughout the building.
