Expert Boiler Repair & Hydronic Heating

Hydronic heating is an art form. Unlike a standard furnace, a boiler system involves complex pressure valves, expansion tanks, and precise water chemistry. Whether you are nursing a 50-year-old cast-iron system or upgrading to a modern Navien combi-unit, you need a technician who understands the science of hot water heating.

We Speak “Radiator”

If you live in a pre-war brick home in the West End, your radiators are the heart of your house. But finding a tech who knows how to service them is getting harder. We don't just suggest “ripping it out.” We know how to maintain the character of your home while improving efficiency.

Vintage System Care

Fixing cold spots in radiators, silencing banging pipes (water hammer), replacing leaking valves, and performing annual system flushes to remove sludge buildup.

High-Efficiency Combi Upgrade

Replacing giant atmospheric boilers with compact, wall-mounted combi-boilers. These units handle both your home heating and your hot water in one machine, freeing up massive amounts of space in your basement.

For semi-detached homes and townhouses, space is money. We install Navien as our primary combi-boiler line, and service Viessmann, NTI, Bosch, and most other major brands. By removing your hot water tank and your old floor-standing boiler, we can often reclaim 20-30 square feet of floor space — perfect for finishing your basement or adding storage.

Radiator Valve & Leak Repair

A leaking valve can ruin your hardwood floors in minutes. We stock specialized radiator keys, air vents (bleeder valves), and thermostatic repair kits to stop leaks and ensure every room in your house gets equal heat.

In-Floor Heating (Radiant)

Nothing beats the feeling of a warm floor on a winter morning. We design and troubleshoot hydronic radiant floor systems for basements, bathrooms, and driveway snow-melts. If your zones aren't firing correctly, we have the diagnostic tools to find the blockage or electrical fault.

Brands We Install & Service

For new installations we lead with the brands we trust most:

• Navien: Our primary install for combi-boilers and tankless hot water. Top-tier tankless technology and a proven service record in Toronto homes.
• Mitsubishi Electric: Where a heat pump or ductless solution makes more sense than a boiler upgrade.
• Rheem: For tank water heaters paired with a hydronic system and combination boiler/tank setups.

On the service side we are fully licensed to repair and maintain most major makes and models — including Viessmann, NTI, Bosch, Weil-McLain, IBC, Buderus, and older atmospheric boilers.

How We Handle Your Boiler Service

• The Diagnostics:We don't just guess. We check the expansion tank pressure, the aquastat settings, and the circulation pump performance.
• The Flush:Hydronic systems build up ‘magnetite’ (sludge) over time. We use specialized cleaners to flush the lines, improving heat transfer and protecting your pump.
• The Solution:Whether it's a simple thermocouple replacement or a new heat exchanger, we explain the costs upfront — no surprises.
