How clean is your hot water? See what is inside your hot water heater 

Many homeowners forget about the fact that water heaters require constant maintenance and upgrade. Common homeowners thinking is that if it works fine, produces hot water and doesn’t leak then there is no need for the upgrade. What a lot of Toronto homeowners do not realize is the fact that most of the older non energy efficient water heaters (most of the water heaters that are older than 2008) have metal liners inside which overtime rust and builds up inside the water heater making your water unsanitary for use. Moreover, all the dirt and rust from water lines that deliver water to your home also keeps on building up in your hot water heater.

Below is a video taken by  our technicians during a replacement of a 15 years old hot water heater in Newmarket, Ontario for a customer was very sure that there was nothing wrong with his old unit as it was still working. What customer saw shocked him as well as many viewers. Almost half of the water inside the water heater was filled with dirt and rust that customer was consuming on a daily basis.


If you are a homeowner, ask yourself few questions:

  • When was the last time your current water heater provider did maintenance on your unit?
  • Is your hot water heater energy efficient or does it still have metal liner inside?
  • When was the last time your hot water heater was drained and flushed?
