Water Heater Tankless Water Heaters in Burnaby, BC

Tankless (on‑demand) water heaters are a common upgrade for Burnaby homes looking to reduce energy use, reclaim utility room space, and get continuous hot water for showers, laundry and dishwashing. This page explains how tankless systems work, the energy and space benefits for local homes, how to size a unit correctly for Burnaby’s incoming water temperatures, recommended types and manufacturers, a professional installation overview (including venting), routine maintenance and common repairs, and what to consider when deciding if tankless is the right solution for your property.

How tankless water heaters work and the benefits for Burnaby homes

A tankless water heater heats water only when a tap is opened. Instead of storing a large volume of heated water, a heat exchanger raises water temperature on demand using gas burners or electric heating elements. For Burnaby residents this means:

• Energy savings: Eliminating standby losses from a storage tank reduces wasted energy, especially valuable if your household has intermittent hot water use.
• Compact footprint: Wall‑mounted units free up closet or basement space—useful in Burnaby homes or condos where square footage is at a premium.
• Continuous hot water: Ideal for families or households running multiple demands at once when properly sized.
• Longer service life: Well‑maintained tankless units often last longer than traditional tanks.

Burnaby’s coastal climate and generally colder winter inlet temperatures make correct sizing and anti-scale measures especially important to preserve performance and longevity.

Common tankless options and recommended manufacturers

Tankless units vary by fuel type and design. Key categories:

• Condensing gas tankless: Highest efficiency, recovers extra heat from exhaust. Good for high‑use households.
• Non‑condensing gas tankless: Simpler venting options but slightly lower efficiency.
• Electric tankless: Compact and ventless; cost-effective for smaller flow demands or where gas is not available.

Trusted manufacturers with proven field performance include Navien, Rinnai, Noritz, Bosch, Takagi, Rheem and Daikin (where available). Condensing models from Navien and Rinnai are popular in the Lower Mainland for efficiency; Bosch and Rheem offer solid electric options for smaller loads.

Sizing and flow‑rate calculations for Burnaby

Correct sizing is the most critical step to ensure a tankless unit meets your household’s hot water needs.

1. Determine peak simultaneous hot water use:

• Shower: 7–10 L/min (low‑flow models ~7.6 L/min)
• Kitchen tap: 8–12 L/min
• Dishwasher: 8–12 L/min
• Washing machine: 10–20 L/min (varies by model)Add the flows of all fixtures likely to run simultaneously to get the required flow rate in L/min.

2. Calculate required temperature rise:

• Typical desired delivery temperature: 45–50°C (113–122°F) for general use.
• In Burnaby, incoming groundwater can be around 6–10°C in winter and higher in summer. Use a conservative winter inlet temperature (about 6–8°C) for sizing.
• Temperature rise = Desired delivery temp − Inlet temp (for example: 50°C − 8°C = 42°C).

3. Match flow and rise to unit capacity:

• Tankless specifications list the maximum flow at a given temperature rise. Choose a model whose published flow at your calculated temperature rise equals or exceeds your peak simultaneous flow.

Example: If peak simultaneous use is a shower (9 L/min) + dishwasher (10 L/min) = 19 L/min, and winter inlet is 8°C with desired output 50°C (42°C rise), select a unit rated for ≥19 L/min at 42°C rise.

Professional installers typically perform a full load analysis and recommend slightly higher capacity to allow for future changes.

Professional installation and venting requirements

Proper installation protects performance, safety and warranty coverage. Typical professional installation steps:

• Site assessment: Evaluate available space, gas supply, venting run, water quality and local codes (strata rules for condos).
• Gas line sizing/upgrades: Tankless gas units need higher instantaneous gas flow than tanks; line and meter capacity may need verification or upsizing.
• Venting: Condensing units require corrosion‑resistant venting and condensate drainage; direct‑vent (sealed combustion) is common. Venting options include sidewall termination with a concentric vent, or vertical chimneys where code permits. Power‑vented configurations may need electrical connections.
• Water and condensate connections: Use appropriate materials and include a condensate neutralizer when required.
• Electrical: Even gas units need electrical for controls and ignition; electric units require significant dedicated circuits and service capacity.
• Permits and inspections: Local permit and inspection ensure code compliance and maintain warranty validity.
• Startup and testing: Calibration of controller settings, combustion analysis for gas units, leak checks and demonstration of operation.

Venting restrictions, especially in Burnaby condos or older homes, often determine whether a condensing or non‑condensing unit is appropriate.

Routine maintenance and common repairs

Routine care keeps a tankless system efficient and reliable:

• Descale/flush annually: Metro Vancouver’s moderately hard water leads to mineral buildup; annual descaling (or more frequent if very hard) is recommended.
• Clean inlet filters and screens: Regularly remove debris to maintain flow.
• Inspect venting and condensate lines: Check for blockages, corrosion or leaks.
• Check gas pressure and combustion: Ensure burner and ignition are operating cleanly.
• Replace sacrificial anode or install a scale inhibitor: For extended service life where appropriate.

Common repairs include ignition failures, sensor malfunctions, scale‑related flow reductions, valve leaks and condensate drain blockages. Prompt maintenance prevents many of these issues.

Warranty, rebates and financing considerations in Burnaby

Manufacturer warranties for tankless systems typically include limited warranties on the heat exchanger (commonly 5–15 years depending on the brand and model) and shorter parts warranties. Warranty terms vary by manufacturer and model and often require professional installation and annual maintenance to remain valid.

Local rebate programs and incentives can offset equipment cost-provincial, utility and manufacturer rebates are periodically available in British Columbia. FortisBC, BC Hydro and manufacturer incentive programs may offer rebates for high‑efficiency equipment; eligibility rules and amounts change, so reviewing current programs when planning a purchase is prudent. Many local dealers also offer financing options that spread payment over time; terms and availability vary.

Is tankless right for your Burnaby home?

Tankless water heaters are an excellent fit when you want space savings, continuous hot water and higher long‑term efficiency. They are especially attractive in Burnaby where utility room space is limited and energy efficiency is valued. Consider tankless if you:

• Have moderate to high simultaneous hot water needs and can size a system accordingly.
• Are prepared to manage water quality (descaling or softening) to prevent scale buildup.
• Have adequate gas or electrical service and feasible venting paths that meet code.
• Live in single‑family homes or townhomes where venting modifications are acceptable; condos require careful strata and venting review.

If your household has very low peak flows or you cannot accommodate venting or gas/electrical upgrades, a high‑efficiency tank storage heater may still be a better option.

Final technical decisions-sizing, model selection and installation approach-are best made after an on‑site assessment that considers Burnaby inlet temperatures, plumbing layout, and venting constraints. A professional evaluation ensures the system selected will meet your hot water needs reliably and efficiently.
