    Why Estate Owners Choose High-Efficiency Boilers

    Quieter, cleaner, lower-cost heat — engineered for the GTA.

    A modern 95%+ AFUE condensing boiler doesn't just replace an older unit — it transforms the entire mechanical room. Modulating burners match output to load, condensing operation captures latent flue energy, and outdoor reset controls lower supply temperatures on milder days. The result: lower gas bills, quieter operation, and a system built to last decades.

    Mechanical Systems We Design & Install

    Six mechanical scopes, engineered to the home — never to a template.

    From a 5,000 sq ft Kleinburg estate boiler plant to a Toronto condensing-boiler retrofit, every Perruzza mechanical install is sized to the heat-loss model and detailed to the equipment and venting requirements.

    Our Design-Build Process

    Three engineered phases — backed by licensed Mechanical Contractors.

    From the first mechanical-room walkthrough to the final annual tune-up, every Perruzza boiler project is delivered by fully licensed Mechanical Contractors — assessed, installed to code, and maintained for the long run.

    01

    Mechanical Assessment

    As fully licensed Mechanical Contractors, we walk the mechanical room, review existing equipment and drawings, and run a heat-loss + DHW demand assessment so the boiler is sized to your home — not a generic template.

    02

    Code-Compliant Installation

    Every boiler, manifold, vent, and gas line is installed to Ontario Building Code, TSSA G1, and CSA B149.1 standards by our licensed Mechanical Contractors — pressure-tested, documented, and inspection-ready.

    03

    Commissioning & Maintenance

    After start-up, our licensed Mechanical Contractors deliver combustion-analyzer printouts and return for annual tune-ups, controls checks, and burner service so your boiler plant runs efficiently for decades.

    Technical Specifications

    The numbers behind a Perruzza boiler plant.

    These are the design parameters we hit on a typical Vaughan or GTA custom-home boiler install — calibrated to the home's heat-loss, DHW demand, and the hydronic emitters the plant has to drive.
