All-Brand Boiler Installation in Coquitlam
Replacing a boiler is not starting over. The heating system in your walls and floors is still good, and a new boiler gives it a better, more efficient source of hot water to work with. Eaton's Heating is based in Coquitlam and installs condensing and combi boiler systems from Navien, Viessmann, and Bosch. Every project starts with a free in-home assessment that examines the existing distribution before we recommend any equipment, and it ends with a written, all-in price. Financeit at zero percent over 12 months is available.

A boiler replacement is different from most heating jobs because everything the boiler connects to matters as much as the unit itself. Piping that has been in the walls for forty years may be narrowed by mineral scale. Zone valves that operated fine on the old boiler's flow rate may stick or fail under a new one's higher output. Radiators that have been heating evenly for decades may need rebalancing once a modern condensing unit changes the water temperature and flow characteristics. The assessment catches all of this before the estimate is written, and the work to address it goes into the price upfront, not as a discovery on installation day.
In Coquitlam, boiler installations break into three categories. The first is the straight swap: an aging boiler in a Maillardville or Central Coquitlam home replaced by a modern condensing unit that connects to existing radiators and piping. The radiators themselves are almost never the problem. Cast iron lasts indefinitely when the water is maintained, and the piping is usually sound if it was done in copper. The second category is the combi conversion, increasingly common in renovated homes across Coquitlam where a single wall-hung unit replaces both the old boiler and the hot water tank beside it, freeing up the mechanical room and eliminating the cost of keeping a tank hot around the clock. The third is radiant floor work, found in custom builds on Westwood Plateau and some of the larger Burke Mountain homes, where the boiler feeds heated slabs and bathroom loops at lower water temperatures through a mixing valve and manifold system that needs precise flow tuning.
Which brand fits depends on which category the project falls into. Navien's combi and heating-only condensing lines handle the majority of Coquitlam's boiler replacements and combi conversions: compact, efficient, and well supported for parts and service. Bosch covers the mid-range across both configurations with equipment that runs reliably for years with minimal attention. Viessmann is the premium tier, built for homeowners who plan to stay in the house for a long time, and its higher-capacity options are what we reach for on multi-zone systems where a single boiler is feeding radiators, radiant floors, and domestic hot water across a large home. The recommendation comes from what the distribution needs, not from which brand earns the highest margin.
Eaton's Heating holds Technical Safety BC licence LGA0200006, FortisBC Trade Ally status, BBB A+ accreditation, and HPCN registration, with full WorkSafeBC coverage. Being based in Coquitlam matters for boiler work specifically because commissioning, the final step that turns a correctly installed boiler into a system that heats evenly, sometimes needs a follow-up adjustment once the home has run through its first real cold stretch. Air pockets that were not present on installation day can surface after a week of heavy cycling. A zone that seemed balanced in mild weather may run short when every floor is calling at once. Having the installer minutes away instead of across the region makes those adjustments simple. Our 400-plus Google reviews at 4.9 reflect systems that perform from the first season onward.
Installation day covers the full sequence: old boiler removed and disposed of, piping assembly connected with isolation valves, air separator, circulator, expansion tank, and backflow preventer, direct venting run to the exterior, gas fitting and electrical completed, and the system commissioned with air purged from every loop, flow balanced zone by zone, and factory warranties registered. Most standard replacements in Coquitlam finish in a single day. If your current boiler has a fixable problem rather than being at the end of its life, start with boiler repair in Coquitlam instead, because a working boiler with a failed pump does not need a $10,000 replacement. And for homeowners considering a switch from hydronic to forced air, we install furnaces and heat pumps too, though the honest advice is usually to keep the distribution you already have.
When a boiler fails, some homeowners wonder whether it is time to switch to a furnace or heat pump instead. In most Coquitlam homes with existing radiators or in-floor loops, the answer is no. Running ductwork through a home that was never framed for it costs as much as or more than a new boiler, the ducts end up squeezed into spaces that compromise airflow, and the quiet, even comfort that hydronic heating provides gets replaced by fan noise and temperature swings. A modern condensing boiler connects to the distribution already in your walls and floors at 95 percent efficiency or higher, and the money that would have gone into ductwork stays in your pocket. The exception is cooling: if you want air conditioning, that requires ducts or a separate system, and pairing a heat pump for summer with the boiler for winter gives you both without tearing out the hydronic system.

A straight swap onto existing healthy piping typically runs $5,000 to $8,000 all-in: boiler, piping assembly, venting, gas work, commissioning, removal, and disposal. Projects that involve combi conversions, zone additions, piping corrections, or larger multi-zone systems climb into the $8,000 to $14,000 range. The written estimate breaks every line out, and the number on it is the final number. Financeit at zero percent over 12 months is available on every project.
It comes down to how much hot water your household uses at the same time. A combi handles space heating and on-demand hot water from one unit, which frees up the mechanical room and stops paying to keep a tank hot around the clock. That works well for most one- and two-bathroom households. In larger homes where multiple showers, a dishwasher, and a washing machine can run at once, the combi's flow rate becomes the limit, and a heating-only boiler paired with a separate hot water source is the setup that keeps up. We sort this out during the assessment based on what your household actually uses at peak, not on a spec sheet.
Yes, and that is the expected path. Radiators, especially cast iron, are built to outlast the boiler by decades. What matters is the condition of the piping and valves between the boiler and the radiators. Scale buildup can restrict flow, corroded fittings can weep under the higher pressures of a modern system, and zone valves that were barely working on the old unit may not respond at all to a new one. The assessment tests flow and valve operation loop by loop, and when a flush or valve replacement is needed, it goes into the estimate and happens during the swap, not as a callback after.
Most boiler replacements in Coquitlam wrap up in a single day when the piping is sound and the new unit connects to the existing layout without modification. The heat goes off mid-morning when the old boiler comes out and returns the same evening once the new system fires and the loops are purged. Homes with hydronic slabs barely notice because the concrete holds its heat through a working day. Projects that involve flushing scaled piping, adding zones, or converting to a combi configuration may extend to two days, and you will know which yours is from the estimate.
That depends on what keeps failing. Pumps, valves, sensors, and ignition parts are worth fixing on almost any boiler that is otherwise sound. A cracked or heavily scaled heat exchanger on a unit past twenty years is where the math usually shifts toward replacement, because the repair cost approaches what a new condensing unit would cost to finance, and the new unit comes with a factory warranty and 15 to 20 percent better efficiency. We give you both numbers and let you decide. If the $400 repair makes sense, we do it. We would rather fix a working boiler than sell a replacement that was not needed.
Commissioning is the step that turns a correctly installed boiler into a system that heats the house evenly. Air gets purged from every loop, starting from the highest points in the system where it naturally collects. Flow gets measured and balanced zone by zone so the farthest radiator or loop gets its full share of circulation instead of the closest zones taking more than theirs. Combustion is checked, the condensate drain is confirmed clear, and factory warranties are registered. Skipping or rushing this step is why two identical boilers in two similar houses can feel completely different to live with. We commission every system we install, and being based in Coquitlam means any follow-up adjustment during the first heating season is a short trip, not a project.
