"Navien tankless installed last month in our Tillsonburg home. No more cold showers! Abdullah explained everything clearly — the gas line upgrade, the recirculation setup, and the rebate paperwork. The team was in and out in one day, and our gas bill dropped noticeably. Excellent service from start to finish."

Frequently Asked Questions About Tankless Water Heaters

Tankless water heater installation in Tillsonburg and Aylmer starts at $3,500 for a high-efficiency Navien or Rinnai system fully installed. This price includes the unit, all materials, TSSA-certified installation, old tank removal and disposal, gas line upgrade if needed, and system commissioning. Larger units for bigger households or those requiring recirculation may cost $4,000–$5,500. Call (647) 550-4220 for a free in-home estimate.
Tankless water heaters offer five key benefits: (1) endless hot water — no tank means you never run out during back-to-back showers or laundry; (2) energy savings of 20-30% compared to traditional tanks since they only heat water when needed; (3) longer lifespan — 20+ years vs 8-12 years for tank units; (4) space-saving design — wall-mounted, frees up basement or closet space; (5) lower operating costs and eligibility for rebates through Enbridge and federal programs.
Both Navien and Rinnai are excellent brands. Navien features industry-leading condensing technology with built-in recirculation — meaning hot water reaches your taps faster without a separate recirculation line. This makes Navien ideal for larger families and homes with multiple bathrooms. Rinnai is known for proven reliability, strong warranty support, and slightly lower upfront cost, making it a great value for smaller households. At Hawana, we install both and will recommend the best fit for your home size, budget, and hot water usage patterns. Both are eligible for rebates.
Standard gas tankless water heaters require electricity to run the control board, fan, and ignition. During a power outage, they will not operate. However, some models (like Navien) can run on a standard generator or home battery backup. If power outages are a concern in Tillsonburg or Aylmer, we can recommend models with lower electrical draw or discuss backup options. Traditional tank water heaters also require electricity for gas valves and electronic controls, so tankless is not unique in this limitation.
Many homes in Tillsonburg and Aylmer require a gas line upgrade for tankless water heaters because tankless units use significantly more gas per hour than traditional tank units — up to 199,000 BTU/hr compared to 40,000 BTU/hr for a typical tank. A 3/4-inch gas line is usually required. Our installation includes a free gas line assessment. If an upgrade is needed, we provide a clear quote before any work begins. In some cases where gas line upgrade is cost-prohibitive, a high-recovery 50 or 60-gallon tank may be recommended instead.
Tankless water heaters qualify for Enbridge Gas rebates of $300 to $1,000 depending on the efficiency rating and current program offerings. The Canada Greener Homes Grant may also provide up to $5,000 for qualifying energy-efficient home upgrades, though this program is currently paused for new applications (check status). At Hawana, we handle all rebate paperwork at no charge and help you understand what rebates apply to your specific installation. Call (647) 550-4220 to discuss current rebate availability.
A standard tankless water heater installation replacing an existing gas water heater in the same location typically takes 4-6 hours. This includes removing the old tank, installing the new wall-mounted unit, upgrading gas line if needed, connecting water lines and venting, and commissioning the system. Most installations are completed in one day. For homes requiring significant gas line upgrades or venting modifications, we provide a clear timeline during the free estimate. We work efficiently to minimize disruption to your household.
No. Hawana sells tankless water heaters outright only — no rental programs. Rental units from companies like Reliance Home Comfort or Enercare charge $30-$50 per month for the life of the unit. Over 20 years (the lifespan of a tankless unit), that's $7,200-$12,000 — far more than the $3,500 outright purchase price. With outright ownership, you own the unit from day one, have no monthly fees, and can choose any TSSA-licensed contractor for service. Call (647) 550-4220 to discuss outright vs rental comparison.
Yes. We serve rural homes across Oxford County and Elgin County, including properties on LP propane in areas like Straffordville, Vienna, and Springfield. For propane tankless installations, we use models specifically designed for LP gas and verify that your propane tank size can support the increased BTU demand. We also provide propane tankless installations for cottages and rural properties. Call (647) 550-4220 to discuss your specific rural location and propane setup.
A properly maintained tankless water heater typically lasts 20+ years. Traditional tank water heaters last 8-12 years. The extended lifespan comes from the absence of a storage tank, which in traditional tanks eventually corrodes and leaks. With annual maintenance (descaling to remove mineral buildup, especially important in Ontario's hard water), tankless units can easily exceed 20 years. At Hawana, we offer maintenance plans from $149/year to keep your tankless unit operating efficiently and extend its lifespan.
