Hot Water That Fits the Way
Your Home Uses It
A tankless water heater can give you hot water on demand while taking up less space than a traditional storage tank. But getting the right results depends on more than choosing a high-efficiency unit.
The unit needs to be correctly sized, properly connected, safely vented, and installed to applicable Ontario requirements. Our tankless water heater installation service takes care of the entire process. We assess your home's hot water demand, determine the appropriate system, inspect the existing gas or electrical setup, complete the required connections and venting, and test the system before we leave.
Whether you're replacing an existing tankless unit or converting from a traditional tank, we can help you determine what your home actually needs.

Tankless Water Heater Installation for Different Home Setups
Tankless-to-Tankless Replacement
Already have a tankless water heater?
Replacing an existing unit can be relatively straightforward when the new equipment is compatible with the existing installation. However, the existing venting, gas supply, electrical requirements, connections and clearances still need to be assessed against the requirements of the replacement unit.
Tank-to-Tankless Conversion
Want to replace your traditional tank with a tankless system?
This can involve more work than a like-for-like replacement. Depending on the equipment and existing installation, modifications may be required to the gas supply, venting, electrical service, water connections, condensate drainage and mounting location.
A site assessment determines what your home will require.
