Tankless Water Heaters in Caledonia

Tankless water heaters heat water on demand rather than storing a tank of hot water that loses heat continuously, making them significantly more energy-efficient for Caledonia households with moderate to high hot water usage. A properly sized and installed tankless unit delivers endless hot water at the correct temperature regardless of simultaneous demand points, provided the flow rate and gas or electrical supply are correctly matched to the unit. Birnie Plumbing and Drains sizes, supplies, and installs tankless water heaters with the venting, gas line, and electrical modifications the system requires.

01

Assess Hot Water Demand

We calculate your peak hot water demand based on fixture count, household size, and usage patterns to confirm the correct unit flow rate and BTU rating.

02

Select the Right Unit

We recommend a unit based on your fuel type, flow rate requirement, and installation location, with clear explanation of operating cost vs. upfront cost trade-offs.

03

Prepare the Installation Site

Gas line sizing, venting configuration, and condensate drain routing are assessed and any required modifications are completed before the unit arrives.

04

Install and Connect

The unit is mounted, gas or electrical connections completed, venting installed, and isolation valves fitted for future maintenance access.

05

Commission and Test

Flow rate, temperature, and simultaneous demand are tested before sign-off. We walk you through the unit controls and maintenance schedule.

Endless Hot Water on Demand

A correctly sized tankless unit delivers continuous hot water at a consistent temperature regardless of how many fixtures are running simultaneously.

Significant Energy Cost Reduction

Eliminating standby heat loss reduces water heating energy consumption by 20 to 40 percent for most households, producing real savings on every utility bill.

Correct Sizing Is Everything

An undersized tankless unit cannot meet peak demand. We calculate your actual peak flow rate before recommending a model, so it performs as expected every time.

Space-Saving Wall-Mount Installation

Tankless units mount on the wall and take a fraction of the floor space of a traditional tank, freeing up mechanical room space for other uses.

Long Service Life

Tankless water heaters have a design life of 20 or more years when properly maintained, significantly longer than conventional tank units.

Gas Line and Venting Modifications Included

Where the existing gas line or venting is not sized for the new unit, we complete all required modifications as part of the installation scope.

Workmanship Guaranteed

All tankless water heater installations are covered by our full workmanship guarantee on labour and installation.
