Sullivan Heights homes from the neighbourhood's main development era typically have straightforward hydronic layouts, which makes them good candidates for either extending existing radiator systems or adding radiant floor heating during a renovation.

Quick answer
Hydronic heating in Sullivan Heights generally involves working with the fairly consistent bungalow and two-storey layouts built through the 1970s to 1990s, which tend to have simpler radiator piping than older character homes elsewhere in Metro Vancouver. That consistency makes upgrades and zoning improvements relatively straightforward, though a technician still needs to assess the specific home's piping condition and whether the original boiler has enough capacity for any added zones.

Because Sullivan Heights was largely built out over a couple of decades, its homes share broadly similar construction approaches, including how radiator piping was typically run. That doesn't mean every home is identical, but it does mean a technician working in this neighbourhood often has a good baseline understanding of what to expect before even seeing the specific property.
A homeowner planning a kitchen or bathroom renovation is often the one who ends up asking about zoning improvements, since opening up walls or floors for other work creates a convenient opportunity to also address heating without additional disruption later.
A technician assessing an older Sullivan Heights system also checks whether the original pressure relief valve is still functioning correctly, since a valve that's seized or slow to respond is a safety concern worth addressing regardless of what other work is being planned.
| Situation | Typical approach | Consideration |
|---|---|---|
| Original rooms with radiator piping intact | Keep and service existing radiators | Sediment and pipe age after decades |
| Basement renovation or finishing project | Radiant floor often considered | Best done during the renovation itself |
| Whole-home system upgrade | Boiler resized for combined zones | Coordinate radiator and radiant response times |
Many original Sullivan Heights systems were installed with simpler zoning than what's available today, sometimes with the whole home on one or two zones regardless of room usage patterns. Upgrading zone valves and controls during a repair or renovation can improve comfort without necessarily requiring a full boiler replacement, provided the existing boiler has adequate capacity.
Ballpark, not a quote: a hydronic upgrade or install typically runs $6,500-$14,000+ depending on scope, with a straightforward zoning improvement on an existing system often at the lower end of that range.
For a Sullivan Heights household deciding between a full system overhaul and a more targeted upgrade, it often comes down to how many individual faults have appeared recently versus how the system has performed overall, since a system with one isolated issue rarely justifies the cost of full replacement while a pattern of recurring problems across multiple zones usually does.
Safety note
Gas boiler and water heater work involves combustion, venting, and gas piping that must be handled by a Technical Safety BC licensed gas fitter. CANRO holds gas licence LGA0043870 and boiler licence LBP0046450. If you ever smell gas near mechanical equipment, leave the home immediately and call FortisBC at 1-800-663-9911 from a safe location.
It's more practical during a renovation when the floor is already being opened up, since retrofitting radiant into a finished slab without renovation work is more disruptive. A technician can discuss options for your specific space.
This depends on the piping's condition and whether it has sediment buildup or capacity issues. A technician assesses this rather than assuming an older system automatically needs replacement.
Often yes, if the existing boiler has adequate capacity. Zone valve and control upgrades can improve room-by-room comfort without a full system replacement.
A technician calculates the heating load of the new zone against the boiler's rated output to determine if it can be added without undersizing the whole system.
Seasonally is typical, particularly at the start of the heating season, though a technician can advise based on how often air tends to accumulate in your specific system.
