How Tankless Water Heaters Work

Understanding the Cost-Efficient Benefits for Your San Jose Home

The design of a tankless water heat enables it to heat water directly, eliminating the need for a storage tank. This helps to avoid standby heat losses often found when using storage water heaters or conventional systems. As soon as the hot water tap is turned on, cold water will travel through a pipe into the unit.

Depending on the type of tankless heater, it will be heated by different methods. In an electric tankless heater, an electric element will heat the water. For a gas-fired tankless water heater, a gas burner will heat the water. Either method allows for the tankless water heater to provide a constant supply of hot water without a storage tank. You also avoid waiting on a storage tank to fill up with enough hot water.

Choosing a Tankless Water Heater in the Bay Area

When comparing tankless water heaters, gas-fired heaters typically produce higher flow rates than electric tankless heaters do. If a tankless water heater is smaller, it may not be able to supply enough hot water for simultaneous or multiple uses in a large household. If you wanted to take a hot shower while running the dishwasher, it might stretch the tankless heater to its limit, leaving you with cold water. Large homes or companies may look into installing multiple systems or "whole house" type tankless water heaters.

With two or more tankless water heaters, a company or bigger household will eliminate any system "stretching" problems by connecting heaters in parallel structure for instantaneous demands of hot water. Another option would be to install separate tankless heaters for your appliances. A washing machine or dishwasher may use a lot of hot water in your home, which means that installing a heater specifically for those appliances would allow for instant hot water elsewhere.

While conventional tanks have low initial costs and venting costs without electricity, tankless water heaters offer continuous hot water, high energy efficiency and compact space design. Choosing to install a tankless system will also allow your system to be electronically controlled, making precise temperature control easier and eliminating water storage issues. The operating costs are much lower and there is low NOx emissions.
