Shaughnessy's large heritage homes run some of Metro Vancouver's oldest hydronic systems, and CANRO services, upgrades, and retrofits them with the house's character in mind.

Quick answer
Hydronic heating in Shaughnessy most often means an original cast-iron radiator system, sometimes updated with a modern condensing boiler, distributed through steel piping that in some homes dates back to the 1910s through 1930s. Because these systems serve large, multi-storey heritage houses with generous room counts, design and service decisions weigh the existing distribution network's condition and capacity as much as the boiler itself, and any radiant floor additions usually happen selectively during a targeted renovation rather than as a whole-house retrofit.

Many Shaughnessy homes were built with steam or hot-water radiator heat as part of their original design, and a large share of those systems have since been converted to hot-water hydronic with a modern boiler feeding the original cast-iron radiators. The radiators themselves are typically oversized by today's standards, which actually works in a modern boiler's favour — a lower water temperature can still deliver adequate heat through that much radiator surface area, which suits condensing boiler efficiency well.
What varies more is the condition of the original steel or copper piping distributing that heat through multiple storeys and often a semi-detached carriage house or converted garage suite, and that piping's condition is usually the deciding factor in whether a system upgrade is straightforward or requires more extensive work.
Adding radiant floor heat to a Shaughnessy property is usually done selectively, most commonly in a renovated kitchen, a new bathroom, or a lower-level suite created during a larger project, rather than replacing the home's original radiators throughout. This lets the character rooms keep their original radiators while newer or renovated spaces get in-floor heat, typically fed from the same boiler with a dedicated zone and mixing valve to bring the water temperature down to what radiant tubing needs.
Because heritage exteriors are often subject to review for visible changes, any new venting or equipment associated with a radiant addition is planned with that in mind from the start, which avoids surprises partway through a renovation.
| Symptom | Likely Cause |
|---|---|
| Uneven heat between floors | Circulator undersized for the total radiator load, or sediment in original piping |
| A specific radiator never gets fully warm | Air trapped in that branch, or a partially closed original valve |
| System takes a long time to reach temperature | Normal for large radiator mass, but worth checking if noticeably slower than before |
| Knocking or banging in the piping | Air pockets or, in older steam-converted systems, pitch issues in the piping |
Most Shaughnessy hydronic upgrades focus on the boiler and controls rather than replacing radiators, since the existing cast-iron units are durable and well-suited to the home. A modern condensing boiler with zone controls can significantly improve efficiency and comfort while leaving the visible radiators untouched, and adding smart zone valves lets different parts of a large house be heated independently, which older single-zone original systems typically couldn't do.
Annual service on a Shaughnessy hydronic system should include checking pressure and expansion tank condition, bleeding radiators throughout the house rather than just the ones that seem cold, and inspecting original valves for seizing, which is common on rarely-adjusted fittings that have been in place for decades. Given the scale of these systems, catching a developing issue during a scheduled visit avoids a much more disruptive mid-winter diagnosis across multiple floors.
Safety note
If you smell gas near the boiler, hear hissing, or notice a yellow flame or soot in the mechanical room, leave the home and call FortisBC at 1-800-663-9911 from a safe location. Gas-fired hydronic systems must only be installed or serviced by a Technical Safety BC licensed gas fitter.
Usually not necessary — original cast-iron radiators are durable and typically well-suited to a new, more efficient condensing boiler, so most upgrades focus on the boiler and controls rather than the radiators themselves.
Yes, this is a common approach during a kitchen or bathroom renovation, typically fed from the existing boiler through a dedicated zone with a mixing valve to match the lower water temperature radiant tubing needs.
They can affect exterior venting placement and any visible equipment changes, so it's worth having a technician familiar with heritage properties plan the work in advance rather than discovering a constraint partway through.
Large radiator systems with significant total mass naturally take longer to reach temperature than a compact forced-air system, though a noticeable slowdown compared to before can point to sediment or a circulator issue worth checking.
Once or twice a heating season is typical for most systems, more often if a particular radiator repeatedly develops air. Persistent air in the same radiator can indicate a slow leak worth investigating.
