Tankless Water Heaters

Save Up to 70% on Your Water Heating Bills With a New Tankless Water Heater

Tankless water heaters not only heat up your water, they heat up your savings too. Because they only start heating water when you need it, a tankless water heater is more energy efficient and will save you money.

Get Access to Instant Hot Water

We chose Knight to install our tankless water heater and water softener and are so pleased with our decision. Great customer service on the phone. The day of the install went very smoothly. Geoff and Kevin were professional and respectful of our home and left no mess. Geoff explained everything and answered all of our questions.

Benefits of a New Water Heater

Switching to a tankless water heater can give you a variety of benefits, including:

  • Endless hot water. Never get stuck taking a cold shower again, no matter how many family members you have.
  • Save on your energy bills. You can reduce gas usage by up to 70%. The Canadian Mortgage and Housing Corporation did a study in 2011 on energy savings from converting to a tankless model. Even though the homes ended up using more water, they still saved an average of 46% on heating costs. Note that’s an average – some saved much more, even though they used more water.
  • Better reliability. A new water heater is less likely to break down than your old one.
  • Free up space in your basement. Tankless water heaters mount on a wall, allowing you to make use of the 9 – 12 square feet a water heater uses.
  • Advanced safety features. When hot water tanks corrode, often the bottom just falls right off. Tankless water heaters have emergency shut downs that stop the water flowing if something’s not right.

With regular maintenance, your tankless water heater can last for 20 years or more.
