The Basics
A boiler installation replaces or installs a hydronic heating system that heats water and moves it through radiators, baseboard heaters, or in-floor radiant loops. It is a different approach from forced-air heating, and it delivers steady, even warmth that suits Northern Ontario homes well.
The work involves removing the old unit where there is one, sizing the new boiler to your home's heating load, connecting the supply and return lines, integrating with your existing distribution system, and testing for safe operation. Modern high-efficiency boilers use condensing technology to pull more heat from combustion gases, reaching AFUE ratings of 90% or higher.
Most installations take one to two days depending on system complexity, accessibility, and whether piping or venting needs to change. Every installation is completed to TSSA standards and includes system commissioning to confirm proper, efficient operation.
What the service includes
Boiler Types
Combi, system, and conventional boilers each suit a different home. The right one depends on your hot water needs, your space, and how your home is set up.
Provide both space heating and on-demand hot water in a single compact unit. A good fit for homes without an existing hot water tank or short on space.
Work with a separate hot water cylinder, well suited to homes with multiple bathrooms or higher hot water demand running at the same time.
Use both a hot water cylinder and a cold water storage tank. Typically found in older homes or chosen when replacing an existing system like-for-like.
Any of these three can be a condensing boiler, which recovers heat from exhaust gases to reach efficiency ratings above 90% and lower your fuel use through a Timmins winter. We recommend LG, Navien, Continental, and Napoleon based on reliability, parts availability in Northern Ontario, and how they perform in the cold, with budget alternatives available when upfront cost is the priority.
If you are weighing hydronic heat against a forced-air system, our furnace installation services cover that side of the decision. And because a system boiler pairs with a separate hot water cylinder, it often makes sense to plan it alongside hot water tank installation so the two systems are sized to work together.
Repair or Replace
Boilers older than 15 to 20 years typically run at 70 to 80% efficiency, which wastes fuel and pushes your heating costs up every month. When repairs become frequent and the bills keep climbing, replacement is often the better investment.
A modern condensing boiler can cut fuel consumption by 20 to 30% compared with an older non-condensing model, and it delivers more consistent heat throughout your home. New boilers carry manufacturer warranties on parts and often include labor coverage, with the specific terms depending on the model and manufacturer. In Timmins, where heating systems run six to eight months a year, those efficiency gains compound into real annual savings.
Signs it is time
The Process
From the first assessment to the final commissioning, here is how a boiler installation goes with us.
We evaluate your existing system, measure your heating load, and talk through your hot water needs and budget so the recommendation fits your home.
You receive a clear quote covering equipment options, installation scope, and timeline. Most customers reach a decision within a week.
On installation day we remove the old boiler, prepare the area, and position the new unit with proper clearances for service access.
We connect supply and return lines, tie into your existing radiators, baseboards, or in-floor system, and install new venting where condensing models require it.
All gas connections are pressure-tested. We commission the system by verifying combustion, water flow, temperature settings, and safety controls.
Before we leave, we walk you through basic operation, thermostat settings, and the maintenance that keeps the system running efficiently.
Commissioning is where a good installation proves itself. After the connections are made, we run a combustion analysis, confirm water flow and temperature settings, and verify every safety control before the system is handed over. It is the difference between a boiler that simply runs and one that runs safely and efficiently for years.
We install LG, Navien, Continental, and Napoleon boilers, and we give you an accurate timeline during the assessment so the work fits your schedule. We serve Timmins, South Porcupine, Schumacher, and surrounding communities within a 300 km radius.
Sizing
Boiler capacity is measured in BTU/h, and it has to match your home's heat loss. Get it wrong in either direction and the system suffers: an oversized boiler short-cycles on and off, which wastes fuel and shortens equipment life, while an undersized one runs flat out in extreme cold and still struggles to keep up.
That is why we calculate heat load rather than guess from square footage alone. We account for insulation, window area, ceiling height, and the Timmins design temperature, which sits around -30°C. Sizing also factors in your hot water needs on combi and system boilers, and homes with in-floor radiant heating or multiple zones get a load calculation for each zone so heat is balanced room to room.

Efficiency
AFUE, or Annual Fuel Utilization Efficiency, measures how much of your fuel actually turns into usable heat. A 95% AFUE boiler converts 95% of its fuel into heat and loses only about 5% through venting. Condensing boilers reach those numbers by cooling exhaust gases below the dew point and extracting the latent heat from the water vapor.
Moving from an 80% AFUE boiler to a 95% model can lower annual fuel costs by roughly 15 to 20%, depending on your usage and fuel prices. In Timmins, with long heating seasons and deep cold, that adds up to hundreds of dollars a year. Modulating burners sharpen the gains further by matching flame output to demand in real time. Some installations may also qualify for provincial or federal rebates, so it is worth verifying current programs with Enbridge or the Canada Greener Homes Grant administrators.
Where the savings come from
Cost
We know price matters, so here is a straight look at what drives it. Equipment cost varies by boiler type, efficiency, brand, and capacity. Combi boilers usually cost more upfront than conventional models, though they remove the need for a separate hot water tank.
Labor depends on complexity. A straightforward replacement where new equipment meets existing connections costs less than one needing new venting, piping changes, or added zone valves. Most Timmins homeowners decide within a week, and when upfront cost is the main concern, we offer budget-friendly alternatives and lay out the trade-offs clearly.

Built for the Cold
Timmins winters regularly drop to -30°C or colder, so a boiler here has to be sized for extreme cold and able to hold comfortable temperatures through long cold snaps. Condensing boilers are well suited to the job: they reach peak efficiency at the lower return water temperatures common with in-floor radiant or generously sized radiators.
A few details make a real difference in our climate. Outdoor reset controls adjust the boiler's water temperature to the weather, easing off in milder spells and ramping up in deep cold. Supply and return lines get insulated in unheated basements and crawl spaces to prevent heat loss and freezing, and we recommend annual service before each heating season to keep small issues from becoming mid-winter breakdowns.
Scope
Every boiler installation we do covers the full job, from removing the old unit to the final walkthrough, with no surprises left for later. Here is what a standard installation includes.
Maintenance
A new boiler is an investment worth protecting, and a little annual care keeps it efficient and reliable for the long haul. Yearly service should cover the heat exchanger, burner, ignition system, and venting, along with a combustion analysis to confirm the air-fuel mix is tuned for both efficiency and safety. Improper combustion drops efficiency and can produce carbon monoxide, so this check matters.
Water pressure should be checked and adjusted, since low pressure weakens heating and high pressure can damage components. On condensing models, condensate traps and drains need cleaning to prevent the blockages that can shut a boiler down. We also test circulator pumps, expansion tanks, and relief valves, and we ask that you keep the area around the boiler clear for combustion air and easy service access.
When something does go wrong between visits, our heating system repair covers boilers along with the rest of your equipment, including emergency support through the heating season.
