A Bosch tankless water heater is an installed appliance which heats your water on demand as it flows through heating elements, while traditional hot water heaters store and continually heat a large volume of water, whether you need it or not.
Also known as instantaneous or on-demand hot water heaters because they don’t store hot water but create it on demand, their increasing popularity is due to their small, compact design and energy efficiency.
Hot water heating alone accounts for 20% or more of the average Canadians’ household’s annual energy costs. Conventional tanks raise the water temperature to the setting on the tank, usually between 120- and 140-degrees Fahrenheit, costing an annual average amount of $450 for the electric and $200 for the gas tank hot water heaters. Even if no hot water is drawn from the tank, the burner switches on at regular intervals to maintain the water temperature.
Bosch Demand tankless water heaters are commonly used by the rest of the world and first appeared in the United States about 25 years ago. Despite the hype surrounding these appliances, they have limitations too. Getting the right one will add joy to your life, the wrong one disappointment and unnecessary expense.
