Sunset's mix of 1940s-to-1960s bungalows and newer infill development means hydronic heating projects here range from extending decades-old radiator systems to designing radiant floor heating into new duplex and laneway construction.

Quick answer
Hydronic heating remains common throughout Sunset because so much of the neighbourhood's original bungalow housing already has radiator piping in place, while newer duplex and laneway infill is frequently built with in-floor radiant systems from the start. A technician's recommendation depends heavily on which generation of construction a property falls into, and whether an older home's original piping is still viable to extend or repair.

Sunset's established bungalows, many built in the 1940s through 1960s, typically carry original radiator systems that have been in place for decades, sometimes modified during a past renovation. Nearby, newer duplex and laneway infill responding to the corridor's growing density is far more likely to have been designed with in-floor radiant heating built in from the start.
Homeowners renovating an older Sunset bungalow's main floor sometimes ask whether it's worth converting the whole home to radiant floors at once, but in most cases a phased approach, upgrading one renovated area at a time while maintaining existing radiators elsewhere, is more practical.
A technician working on an original Sunset radiator system also checks whether bleed valves on individual radiators still operate smoothly, since seized valves from decades of limited use can make routine seasonal maintenance more difficult than it should be.
| Construction type | Typical system | Key consideration |
|---|---|---|
| Original mid-century bungalow | Radiator piping, decades old | Condition and capacity of existing piping |
| Newer duplex or infill | In-floor radiant, designed in from start | Zoning and manifold balancing at commissioning |
| Laneway house on an older lot | Independent radiant or shared zone | Distance and capacity from main house |
Where a Sunset property has both an original house and a newer laneway house, the two structures usually need to be zoned independently, since they were built decades apart with different heating designs. Some properties run a shared boiler with separate zones, while others find a dedicated smaller system for the laneway house more practical, depending on distance and existing capacity.
Ballpark, not a quote: a hydronic install or upgrade typically runs $6,500-$14,000+, with cost depending on how much new zoning or piping work is needed.
For a Sunset household planning a multi-year renovation in stages, it's worth discussing the eventual hydronic layout early on, even if only one room is being renovated immediately, since planning zoning and piping routes with the full picture in mind can save having to redo work when later phases of the renovation begin.
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.
Often at least partially, depending on its condition. A technician checks for sediment buildup and pipe integrity before recommending whether to keep, repair, or replace sections.
Many do, since in-floor radiant is commonly designed into newer duplex and infill construction from the start, unlike older bungalows that were originally built for radiators.
It depends on distance from the main house's boiler and available capacity. Many laneway houses end up with an independent setup since extending an older system that far isn't always practical.
Yes, this is common, where a renovated room gets radiant floors while the rest of the home keeps its original radiators, with zoning set up to manage the different response times.
This is usually a manifold balancing issue where flow isn't distributed evenly across loops, which a technician can typically adjust without replacing equipment.
