Overview
Boiler replacement in Burnaby's older homes
Many detached homes in Burnaby Heights, Capitol Hill and around Deer Lake still have the cast-iron boiler they were built with, venting up a brick chimney and feeding big radiators or baseboards. When that boiler finally needs replacing, a modern condensing boiler can use far less gas. But a boiler replacement in Burnaby done well involves more than unbolting the old unit and connecting a new one.
Decades of sludge in the pipes can clog a new heat exchanger. Radiators may need lower water temperatures to let the new boiler condense. And if a gas water heater shares the old chimney, it may be left venting alone into a flue that is now far too big. Able Pro plans for all of this and quotes it clearly before work begins.
What changes when you go condensing
These are the parts of the job that make a replacement last.
New plastic venting
Condensing boilers vent through PVC or polypropylene out a wall or roof, not the masonry chimney.
The orphaned water heater
A water heater left alone in an oversized chimney can draft poorly. A liner or other fix may be needed.
Radiator temperatures
Generous cast-iron radiators often heat well at lower water temperatures, which helps the boiler condense.
Condensate disposal
We add a neutralizer and a drain route, which older basements were never set up for.
Outdoor reset
Water temperature tracks the weather, so mild Burnaby days use cooler, more efficient water.
Local service
Replacing boilers in Burnaby neighbourhoods
The older houses of Burnaby Heights and Capitol Hill are where cast-iron replacements are most common, often with original radiators worth keeping. Around Deer Lake and Lochdale, we see more baseboard systems that were added or extended over the decades.
Homes in South Slope and Edmonds frequently have suites, so a replacement is a chance to add proper zoning. Townhomes near Metrotown tend to be swapping an older combi for a newer one.

Questions homeowners ask us
Still unsure? Call (236) 222-2222 and talk it through with us.
Will my Burnaby Heights radiators work with a new condensing boiler?
Most cast-iron radiators work very well. They are large, so they can heat rooms at lower water temperatures, which lets a condensing boiler run efficiently for much of the season. We check radiator sizing against heat loss to confirm.
What happens to my chimney after the boiler is removed?
If nothing else uses it, it can be capped. If a gas water heater still vents into it, the chimney may be too large for it alone, causing poor draft and condensation. We check and recommend a liner or another solution.
Why do you flush the old system?
Old cast-iron systems carry sludge and rust particles. Modern heat exchangers have narrow passages that clog easily, so flushing and adding a separator protects the new boiler.
Can I replace my old boiler with a combi in Burnaby?
Yes, if your hot water use suits it and the boiler can be placed with a proper vent route. Many owners like the space a combi frees up. For big families, a boiler with an indirect tank may suit better.
