Ontario has more rented water heaters than any other province. Here’s the 2026 economics breakdown and technology comparison. **The rental trap:** $20-$40/month rental = $3,600-$9,600 over 15-20 years, for an appliance costing $800-$2,500 to own. Buyout fee when selling: $1,500-$3,000 (often required to close). Read your rental agreement terms before any changes. **Technology comparison:** **Gas tank (40-50 gallon):** Most cost-effective for most Ontario homes. UEF 0.67-0.70. Lifespan 10-15 years. Supply and install (owned, including rental removal): $1,200-$2,200. **Gas tankless (condensing):** Unlimited hot water, no standby loss. UEF 0.90+. Requires 3/4" gas line and dedicated flue. Supply and install: $2,500-$5,000. Note: cold water sandwich effect is real – brief cold burst between consecutive draws. **Heat pump water heater (electric):** 2-3x efficiency of conventional electric. Best in conditioned spaces that are air-conditioned (HPWH cools the space as it heats water). Not suitable for small unventilated mechanical rooms. Canada Greener Homes Grant: up to $1,000 rebate. Supply and install: $1,800-$3,500. What water heater do you have? Has anyone bought out their rental unit recently – was the buyout worth it? _Water heater and HVAC questions at [home.renovation.reviews](https://home.renovation.reviews)_
