Deer Lake's larger Burnaby homes often have the fixture count to make tankless a strong option, and CANRO sizes and installs these systems locally.

Quick answer
A gas tankless water heater supplies hot water on demand rather than from storage, which suits many Deer Lake homes given the number of bathrooms in some of the neighbourhood's larger properties. Installation requires confirming the gas line can handle the unit's peak draw, running venting rated for the higher exhaust temperature involved, and sizing the unit to the household's real simultaneous fixture use — as a ballpark, not a quote, installation typically runs $3,500 to $7,500 depending on the gas and venting work required.

Deer Lake's larger, more established Burnaby properties frequently have three or more bathrooms, and a household running multiple showers or a bath and laundry at the same time can outpace a single standard storage tank fairly quickly. Tankless systems solve that by heating water on demand rather than drawing down a fixed stored volume, which is a common reason homeowners here ask about switching during a renovation or when an aging tank finally needs replacing.
Freeing up mechanical room space is a secondary but real benefit too, particularly in homes where the mechanical room has become a catch-all storage space over the years.
| Item | Why It Matters | What We Check |
|---|---|---|
| Gas line capacity | Tankless units draw more gas at peak than most tanks | Line size and total connected load on the meter |
| Venting type | Tankless exhaust runs hotter, needs rated venting | Existing vent material and routing |
| Fixture count | Determines the flow rate the unit needs to handle | Simultaneous hot water use across the household |
| Mounting location | Affects venting run length and future service access | Wall space, clearances, exterior termination |
Older Deer Lake homes with a gas line originally sized for a furnace and a standard tank sometimes need that line reassessed or upsized to properly support a tankless unit's peak draw — this gets checked before scheduling, not assumed.
A household with three or four bathrooms and a family running hot water at overlapping times needs a unit — or in some cases a paired setup — sized to actually keep up, which is different from what a smaller household with one or two bathrooms would need. This gets worked out from your home's real usage pattern rather than defaulted to a standard mid-size unit.
Metro Vancouver's comparatively soft municipal water helps reduce how often descaling is needed here versus harder-water regions, but it's still a maintenance item over the unit's working life, not something to skip.
We generally set homeowners up with a simple maintenance reminder rather than expecting them to track service intervals themselves, since it's an easy thing to let slide once the system is running well and out of sight. A quick annual check catches most issues early, well before they turn into a no-hot-water call on a busy morning.
Safety note
If you smell gas anywhere near a water heater, boiler, or gas line, do not flip switches, light anything, or search for the source yourself. Leave the house, get everyone else out too, and call FortisBC at 1-800-663-9911 from a neighbour's place or your cell once you're outside. Gas piping, venting, and combustion equipment in your home must only be worked on by a Technical Safety BC licensed gas fitter.
Often yes, particularly for households with three or more bathrooms where simultaneous hot water demand can outpace a standard storage tank.
Not always without reassessment. Tankless units draw more gas at peak than a typical storage tank, so line size and total meter load get checked before installation.
A larger household with several bathrooms needs a unit sized to handle realistic simultaneous demand, which is worked out from your actual usage pattern rather than assumed from home size alone.
Yes, since the unit mounts on the wall and eliminates the floor footprint a storage tank requires, which matters in mechanical rooms that have become storage space over the years.
As a ballpark, not a quote, installations generally run $3,500 to $7,500 depending on the gas and venting work required for your specific home.
It helps limit scale buildup compared to harder-water regions, but periodic descaling and an annual combustion check are still part of proper maintenance.
