How They Work
San Francisco Tankless water heaters or on demand water heaters heat water directly without using a storage tank. Therefore, the San Francisco tankless water heaters avoid the standby heat losses associated with storage water heaters. When a hot water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water. As a result, Tankless water heaters San Francisco deliver a constant supply of hot water. You don't need to wait for a storage tank to fill up with enough hot water. However, a San Francisco Tankless water heaters output limits the flow rate.
Typically, Tankless water heaters San Francisco provide hot water at a rate of 2-5 gallons (7.6-15.2 liters) per minute. Gas-fired demand water heaters produce higher flow rates than electric ones. Sometimes, however, even the largest, gas-fired model cannot supply enough hot water for simultaneous, multiple uses in large households. For example, taking a shower and running the dishwasher at the same time can stretch a San Francisco Tankless water heater to its limit.

You can also install separate Tankless water heaters San Francisco for appliances-such as a clothes washer or dishwater-that use a lot of hot water in your home.
