Tankless water heaters are the bomb! They are quiet and super-efficient, but what many people don’t realize is that tankless water heaters need maintenance as well. And much of the maintenance completed for tank water heaters is similar to the maintenance performed on tanks. Summer is the perfect time to run some annual maintenance on your system.
We’ll let Greg and Brandon from G&C Plumbing and Heating tell you more.
“Scaling can have a major effect on a water heater because the mineral buildup clangs around in the tank and causes problems with pressure, temperature, and potential corrosion,” said Greg Sheck, Grand Master from G&C. “Tank water heaters need flushing every now and then to offset this effect.”
- Water has a high content of minerals in it – Calcium and magnesium being the most common. When mineral deposits are left behind in appliances or pipes, it’s called “scaling.”
- Scaling can affect the heat exchanger of your tankless water heater. “That’s what heats up the water in the first place” said Greg. “You need it to be clean, so the water heats efficiently.”
- Scaling makes your burners work harder and can overwork an on-demand system to the point that it breaks down – noooooooo!
The guys at G&C use a noncorrosive solution to clean the heat exchanger and recommend you have them come out to service the system annually. Otherwise, you can see what happens here when you DON’T keep the filter clean.
Even with annual maintenance, most tankless systems typically last for about 20 years. If your system starts to fail much sooner than this, it may be due to a lack of maintenance and whether you start to do it yourself or call Greg and Brandon, here are some things to know and assist with maintenance tasks:
- What type of water heater do you have?
- Is your water heater natural gas, electric or propane?
- Is it a basic tank or a tankless design?
- What is the serial number?
- How do you turn off the water?
- How do you shut off the fuel or power supply?
- Is the water heater area clear?
The more you know is better for the guys – that’s what they tell us, anyway! If you need help or have questions about your instantaneous water heater (any water heater, actually) please give Greg and Brandon a call and they’ll be happy to help keep your system in good working order.
