Tankless Water Heaters in Toronto

A tankless water heater heats water only when you need it, so you get continuous hot water, lower energy bills and a free corner of the basement where the old tank stood. POM Plumbing provides tankless water heater installation, repair and maintenance across Toronto and the GTA, including Navien, Rinnai, Noritz and Rheem tankless and combi-boiler systems.

Our licensed plumbers size the unit to your household, upgrade the gas line and venting where needed, and install everything to code so the system runs efficiently for 20 years or more.

    Tankless Installation Process and Cost

    How Our Tankless Installation Works

    1. Sizing visit. We count fixtures, check gas supply and venting routes and recommend the right model.
    2. Clear quote. You get one price for the unit, materials, permits and labour.
    3. Installation. We remove the old tank, mount the new unit and run gas, water, venting and condensate lines.
    4. Start-up and test. The system is commissioned, tested at every fixture and explained to you.

    Tankless Water Heater Installation Cost in Toronto

    The final price depends on the model, gas line upgrade and venting route. Typical ranges:

    ServiceTypical cost
    Tankless water heater installationfrom $3,800 installed
    Combi boiler installationquoted after site visit
    Tankless descaling / maintenancefrom $200
    Tankless water heater repairfrom $200

    Tankless vs Tank Water Heater

    A tank is cheaper to install and works well for smaller households. A tankless water heater costs more upfront but lasts about twice as long, saves energy and never runs out of hot water. For families of four or more, or homes with a large soaker tub, tankless usually wins over the long term.

    Tankless Water Heater FAQ

    • How much does tankless water heater installation cost in Toronto?

      Tankless water heater installation typically starts from about $3,800 installed. The total depends on the model, whether the gas line needs upgrading and how far the venting must run. We confirm the price after a short sizing visit.

    • Do you repair all tankless brands?

      Yes. We repair and maintain Navien, Rinnai, Noritz, Rheem, Bosch and other tankless water heaters, including error codes, ignition problems and scale build-up.

    • How often does a tankless water heater need maintenance?

      Once a year in most Toronto homes. Hard water leaves scale in the heat exchanger, and annual descaling keeps the unit efficient and protects the warranty.

    • Can a tankless water heater run out of hot water?

      No, as long as it is sized correctly. If too many fixtures run at once, the flow may drop or the temperature may dip, which is why we size each unit to your household.

    • Is my home suitable for a tankless water heater?

      Most homes are. The main checks are gas supply size, a venting route to the outside and a place to drain condensate. We confirm all three during the sizing visit.
