Coquitlam's hard water changes everything
Coquitlam's water comes off the Coquitlam Lake watershed and runs 80–110 ppm hardness — well above Vancouver's. That mineral load scales the heat exchanger of any tankless unit within 18 months unless you descale annually.
Renting solves this: the descale is included in the annual tune-up. Owners who skip it lose 30% efficiency by year 3 and replace the exchanger by year 7.
Gas vs electric tankless in Coquitlam
Gas condensing tankless units handle simultaneous showers and dishwasher loads — the right pick for 3+ bedroom Coquitlam homes. Electric tankless units are quieter and cheaper to install but require a 200A panel and struggle in winter when incoming water is 4–6°C.
- Gas condensing: $59–$89/mo, 199K BTU, 11 GPM at 60°F rise
- Electric: $39–$69/mo, 27 kW, 5–6 GPM at 60°F rise
- Both include annual descaling and lifetime warranty
Recirculation for older Coquitlam homes
If your Coquitlam home was built before 1990 with the master bath at the far end of the house, you'll want a recirculation pump on the tankless to avoid 30-second hot-water lag. We add it at install — included in the rental on bundled packages.
