Emergency Tankless Water Heater Repair

A tankless water heater, also called instantaneous hot water, on-demand heater, or readily-on-demand water heater, is a water heater that instantly heats water as it flows through the unit. Some system carries a buffer tank, while others don’t retain any water internally except for what’s inside the heat exchanger. Copper heat exchangers are preferred in these units because of their high thermal conductivity. 

How Does tankless water heater work:

  • Whenever a hot water tap is opened, the tankless water heater detects the flow of water by using a flow sensor which sends a signal to the circuit board for it to turn on the combustion blower fan motor.
  • The electronic spark igniter turns on, and the gas valve activates and opens to provide fuel for the system to light.
  • The cold water then gets heated as it passes through the hot heat exchanger.
  •  An outlet temperature sensor then monitors the desired water setpoint temperature.  
  • Desire hot water then travels to the outlet location. 

Tankless water heaters are great at saving energy on gas and electric bills. With this system installed in your home or office building, you will always have the comfort of unlimited hot water compared to traditional hot water tanks. Like any other system, these systems require maintenance, which should be done twice, once or every two years, depending on the water’s hardness. Manufacturers strongly advise this to be done for you to have a long-term working system and, in some cases, to maintain the warranty. It is required by Technical Safety BC to have a licensed gas contractor install this equipment due to safety and potential hazards.

Maintaining your tankless water heater is very important and should be done at least once per year. So, by not properly maintaining the system regularly, you will have minerals build up inside the water heater. This means that the entire system must be flushed to prevent damage or a loss of efficiency.

NOTE: If living in an area with hard water, customers should consider flushing their heater at least twice a year.

Some customers may want to try performing the tankless water heater repair on their own. Doing so can lead to potential risk or even damage to the unit. We recommend calling professionals for safety and peace of mind.
