When to Replace Your Water Heater in London, Ontario
Homes in London rely on consistent hot water for daily use, from bathing to laundry to cooking and cleaning. Factors such as household size, water usage patterns, and the age of existing equipment all influence how well a water heating system performs over time.
As systems age, efficiency can decline, and reliability may be affected. Our team can help determine whether maintenance, replacement, or an upgraded water heating solution is the best fit for a home’s current and long-term needs.
How hard is the water going into London water heaters?
Harder than Ontario’s guideline. London’s tap water is treated Lake Huron and Lake Erie water, bought from the two regional systems run as Huron Erie Water, and the City’s 2025 report measured 110 to 126 mg/L of hardness in London’s own system. On heating, hard water tends to form scale deposits, as Ontario’s drinking water guidance notes.
- 110 to 126 mg/L London’s own water system, June 2025: about 6.4 to 7.4 grains per gallon
- 80 to 100 mg/L Ontario’s operational guideline for hardness, as calcium carbonate
