Newer Clayton Heights homes rarely need infrastructure upgrades for a water heater replacement, but sizing for larger households is where CANRO focuses.

Quick answer
In Clayton Heights, water heater replacement is less often about outdated gas or venting infrastructure, since most homes are recent construction, and more often about correctly sizing a new unit for a larger household, sometimes including a secondary suite, than the original builder-installed unit provided. A licensed tech assesses actual demand before recommending a replacement.

Clayton Heights is one of Surrey's newer neighbourhoods, and most homes here are large, recently built, and already equipped with gas infrastructure suited to a modern household. That means a replacement call is less often about bringing an old home up to current standards and more often about the original unit being undersized, or simply reaching the end of its service life after 10 to 15 years.
Builder-grade water heaters are sometimes installed to a minimum spec rather than sized for how a family actually lives, especially in homes with multiple bathrooms or a secondary suite added after the original build. Replacement is often a good opportunity to correct sizing rather than simply match what was there before.
| Factor | Tank | Tankless |
|---|---|---|
| Existing gas infrastructure | Usually already adequate | Usually already adequate or close to it |
| Good fit for large households with peak demand | Limited by tank recovery rate | Matches continuous demand well when sized correctly |
| Upfront cost | Generally lower | Higher, though infrastructure is often already suitable |
| Fits a secondary suite's independent demand | May need a second tank | Can often be sized for combined household use |
Because gas and venting infrastructure in newer homes is typically already close to tankless-ready, the decision here often comes down to household hot water habits rather than what upgrades the home needs.
A straightforward swap, whether staying with a tank or moving to tankless, is usually quicker in newer construction than in an older home, since the underlying gas and venting infrastructure rarely needs significant modification. Ballpark cost: tankless installation runs $3,500 to $7,500, and if a full boiler-based system replacement is what is actually needed, that's priced individually, confirmed after we have assessed the specific equipment and household demand.
Before booking a replacement, it is worth checking a few things yourself: how quickly the household runs out of hot water during a typical busy morning, whether that has changed recently, and whether any fixtures seem to get noticeably less hot water than others, which can point to a distribution issue rather than the water heater itself.
If your home has a tankless unit already and you are simply looking at whether it still matches your household's needs, note the age of the unit and any recent performance changes, since that context helps us assess whether the issue is wear, sizing, or something else entirely.
Safety note
If you ever smell gas (a rotten-egg odour) or suspect a carbon monoxide problem, leave the home right away, do not flip switches or light anything, and call FortisBC at 1-800-663-9911 from outside before calling anyone else. Any gas connection, venting change, or pressure work on a boiler or water heater in BC must be done by a Technical Safety BC licensed gas fitter; CANRO carries gas licence LGA0043870 and boiler licence LBP0046450.
Builder-grade units are sometimes sized to a minimum spec rather than to how a household actually uses hot water, particularly in a larger home with multiple bathrooms. Replacing with a correctly sized unit often resolves this.
Often yes, or a second unit, depending on the combined demand. It is worth planning this before the suite is finished rather than discovering a shortfall afterward.
It can be, particularly for households with high simultaneous demand, and since infrastructure in newer homes is often already close to tankless-ready, the switch tends to be more straightforward than in an older home.
Generally quicker than in an older home, since gas and venting infrastructure rarely needs significant modification, though correctly sizing the new unit for the household can take some upfront discussion.
Roughly 10 to 15 years for a standard tank, similar to any home, though this varies with usage, water quality, and maintenance rather than being guaranteed.
