A recirculation system keeps hot water primed near your fixtures so you are not running the tap for a minute waiting for heat to arrive.

Quick answer
A hot water recirculation system uses a small pump, either on a timer, an aquastat, or a demand-activated button, to circulate water from your gas water heater through a dedicated or existing return line so hot water arrives at distant fixtures faster. In a multi-storey New Westminster home, this is most useful when a bathroom or kitchen sits far from the mechanical room and long waits for hot water are a daily annoyance rather than an occasional one.

A dedicated-return system runs a small pump that continuously or periodically pushes hot water through a loop back to the water heater, keeping the line primed. A demand system instead uses a pump near the farthest fixture, activated by a button or motion sensor, that pulls water through the cold line and returns it to the tank until hot water arrives, at which point it shuts off. Demand systems tend to use less energy since the pump is not running constantly, but they do require either an existing dedicated return line or a bridging valve under the farthest sink.
Both approaches work with a standard gas storage tank. Tankless units can also support recirculation, but the unit needs to be a model designed for it or paired with a small buffer tank, since a tankless heater that is not built for frequent short-cycling from a recirc pump can wear its heat exchanger faster than intended.
| Approach | What It Requires | Best Fit |
|---|---|---|
| Dedicated return line | New piping run back to the water heater | New construction or a major renovation |
| Demand pump with crossover valve | Small pump installed under the farthest fixture, no new piping | Retrofits in existing homes, most New Westminster cases |
| Timer-based pump on existing loop | Requires an existing return line already in place | Older homes that happen to have one |
Most New Westminster retrofits use the demand-pump-with-crossover-valve approach, since running new piping through finished walls in an established home, particularly the older character stock around Queens Park or the Brow of the Hill, is disruptive and costly compared to a compact pump installed at the point of use.
New Westminster's housing stock includes a large share of multi-level character homes on steep hillside streets, plus a growing number of townhomes and low-rise condos where the mechanical room can be a full floor or more away from a primary bathroom. In the older hillside homes, particularly ones with additions or basement suites, hot water runs can be unusually long, and residents often notice they are running the shower tap for well over a minute before it warms up. That wasted water down the drain, not just the wait itself, is usually what motivates the recirculation conversation.
In townhome and rowhome developments along the Fraser River waterfront and in Sapperton, mechanical closets are often centrally located, so the benefit is more modest, but a recirc pump can still noticeably improve the second-floor ensuite experience in a three-storey layout.
A demand-pump retrofit is typically a half-day job for a licensed technician: installing the pump and crossover valve under the sink, wiring or battery-powering the activation button, and confirming the system primes and shuts off correctly. It does not require a gas permit on its own since it is a plumbing and low-voltage electrical addition rather than gas work, but if the visit also includes water heater service or a tank swap, that portion would fall under gas fitting rules and any applicable City of New Westminster permit.
If you are also considering a tankless conversion at the same time, that installation runs roughly $3,500 to $7,500 as a ballpark, not a quote, and is a reasonable point to build recirculation compatibility into the plan from the start rather than adding it later.
Safety note
If you ever smell gas, hear hissing near a gas line, or suspect a venting or carbon monoxide problem, leave the home immediately and call FortisBC at 1-800-663-9911 from a safe location before doing anything else. Do not attempt to relight a pilot or reset a gas appliance yourself if you cannot identify the cause of the problem; wait for a Technical Safety BC licensed gas fitter.
It can modestly, since the water heater cycles more often to maintain temperature in the loop, though a demand-activated system with a timer or occupancy schedule minimizes this compared to a pump that runs continuously.
Usually not. A demand pump with a crossover valve installed under the farthest sink avoids new piping runs entirely, which is the retrofit approach used in most existing New Westminster homes.
Yes, but the tankless unit should be a model designed for recirculation or paired with a small buffer tank, since frequent short cycling can otherwise add wear to the heat exchanger over time.
A demand-pump retrofit is typically a half-day job. A dedicated-loop system involving new piping takes longer and depends on wall and floor access.
Generally no for the plumbing and low-voltage pump portion, since it is not gas work. If the same visit includes water heater replacement or gas line changes, that separate scope would need a permit.
