⚠️ 7 Signs It's Time to Replace Your Water Heater

London Ontario's Hard Water Shortens Water Heater Life
London's municipal water is moderately hard, typically measuring 120–180 mg/L of calcium and magnesium. This accelerates sediment buildup inside tank water heaters — reducing efficiency, increasing energy costs, and shortening the unit's lifespan to the lower end of the 10-12 year range. It also accelerates tankless water heater mineral buildup (requiring annual descaling) and degrades anode rods faster than softer water regions. Hawana factors London's water quality into every water heater recommendation.
Three Types of Water Heaters — Which Is Right for You?
The right choice depends on your home's size, existing fuel type, budget, and long-term priorities. Hawana recommends after an in-home assessment.

"Hot water tank failed on a Sunday morning — called Hawana and a tech was here within 3 hours. Tank replaced and hot water back the same afternoon. He also showed me the condition of the anode rod on the old unit — completely corroded, which he said is typical for London's water. Very professional."
"Had a Navien tankless installed to replace our aging tank. Hawana handled everything — new PVC venting, gas line upgrade, permits. The difference in our gas bill was noticeable within the first month. Abdullah also walked me through the annual descaling requirement, which no other company had even mentioned."
"Switched from an electric tank to a hybrid heat pump water heater. Hawana recommended it based on our basement setup and helped us get the Canada Greener Homes rebate paperwork sorted. The unit has been running 4 months and our hydro bill for hot water is dramatically lower. Very happy."
