Tankless Water Heater

Tankless Water Heater Services in Concord, CA, and Surrounding Areas

Instantaneous hot water is a comfort that brings luxury to any home. Also known as tankless water heaters and demand water heaters, these systems produce hot water exactly when it is needed. 

In contrast to traditional storage water heaters that constantly produce hot water, tankless systems save money by reducing energy costs by only heating water as it is used. You would not leave your heat on while you take a vacation, so why would you spend money heating water when you do not need it?

Your Tankless Water Heater Specialist

Tankless water heaters do not store water and therefore do not require a large storage tank that takes up space in your home. Storage water heaters lose heat and can cost a lot of money in maintenance over time. A tankless system works by heating water using heating elements as it travels through the system after you turn on the hot water tap. In a gas-based tankless system, the gas heater is responsible for heating the water. The end result is a consistent supply of hot water that will not run out, unlike storage water heaters.

The rate of hot water produced by a tankless water heater is two to five gallons per minute, depending on the heating style used. Gas-fired tankless systems produce hot water at a higher flow rate than electric tankless water heaters. If your home is small and your hot water requirements are low, then a smaller tankless water heater is sufficient to provide the water that you need. If your demand is higher, then a “whole house” tankless water heater or two or more tankless systems will be able to keep up with the demand of your household. Certain appliances, such as dishwashers or washing machines, can benefit from having their own tankless hot water system installed.

Yearly Maintenance: Tankless Water Heater Flush

Flushing your tankless hot water heater is necessary to ensure it continues to work correctly and that the warranty remains valid. If mineral deposits, sediment, and other debris are left unchecked over time, they can build up and block the water flow, causing the unit to malfunction or shut down entirely.

Professional assistance is recommended for best results. Our annual service includes flushing out the system to clear away any buildup before checking for any additional repairs or adjustments that need to be made. Not only does this help protect your investment from becoming damaged, but it also ensures that you always have access to hot water when needed. Regular maintenance can go a long way toward protecting your tankless hot water heater and ensuring its longevity.
