Boiler Weather Compensation Setup Guide for Vancouver
Published: July 21, 2026 — CANRO Heating & Cooling — Greater Vancouver, BC
How Weather Compensation Works
Weather compensation adjusts the boiler water temperature based on outdoor temperature. On mild days (5-10°C), the boiler runs at lower temperatures (40-50°C). On cold days (-5°C), the boiler runs hotter (60-70°C). This improves efficiency on mild days when lower temperatures are sufficient.
Vancouver Optimal Settings
For condensing boilers in Vancouver, use a weather curve with 55°C water at -5°C outdoor and 35°C at 10°C outdoor. This keeps the return water below 55°C most of the time, maximizing condensing efficiency. Fine-tune by adjusting the curve up or down 1-2°C based on your home comfort.
Installation and Cost
Weather compensation requires an outdoor temperature sensor ($50-150) and boiler control configuration. Many modern boilers (Navien, Viessmann, Baxi) have built-in weather compensation that just needs activation. Professional configuration costs $100-200. Energy savings: 5-15% annually.
