Water Heater
Installation London Ontario.
From $2,700.
No Rental. Same-Day.
A 10–12 year old water heater in London Ontario is not a question of if it will fail — it’s a question of when and whether you’re prepared. London Ontario’s moderately hard water (120–180 mg/L) accelerates sediment buildup, reducing efficiency and shortening tank lifespan below the national average. If your tank is over 10 years old and rumbling, showing rusty water, or leaking — call now. Same-day replacement is available.
Gas tank water heater: Rheem Performance Power Vent from $2,700 all-in. GSW also available. TSSA permit and inspection included. Old tank removed and taken away. No rental — you own it.
Want tankless instead? Navien NPE-S from $3,500 all-in — endless hot water, 0.97 UEF, 20+ year lifespan. See our dedicated tankless page →
Navien Tankless.
Same-Day Available.
No rental, no monthly fee. TSSA permit + inspection included. Old unit removed. Enercare/Reliance rental replacement specialists.
When Your Water Heater Needs
Replacement vs Repair
A water heater that fails completely is almost always a water heater that showed warning signs for weeks or months. Here’s exactly what to watch for and what to do.
Water pooling at the base of the tank or dripping from connections means the tank has failed internally or externally. A leaking tank cannot be repaired. Shut off the gas supply valve and cold water inlet valve immediately. Call Hawana at (647) 550-4220 for same-day replacement. Left unchecked, a leaking tank can cause significant water damage within hours.
A gas tank water heater over 10 years old in London Ontario’s moderately hard water (120–180 mg/L per City of London data) is in its failure window. Replacement before failure avoids emergency conditions — you choose the timing, the brand, and whether to go tank or tankless. Don’t wait for it to fail at 2 AM in January.
Orange or brown tinting in hot water (but not cold water) indicates internal corrosion of the tank. Once the internal corrosion has progressed to this stage, it cannot be reversed. The tank is contaminating your hot water supply. Replacement is the only solution. Call (647) 550-4220 for same-day replacement.
Loud rumbling, popping, or banging during heating cycles is the sound of water boiling under a thick layer of sediment on the tank floor. This sediment buildup reduces efficiency and stresses the tank liner. On a tank over 7–8 years old, this is a replacement signal — the efficiency loss is accelerating and the tank is entering its failure window. Call (647) 550-4220 to discuss options.
If your tank is under 8 years old, insufficient hot water is likely a thermostat, burner, or dip tube issue — call for a repair assessment ($175 flat). If the tank is over 8 years old, repair cost rarely justifies the remaining lifespan. Abdullah provides an honest repair-vs-replace recommendation on every service call. Call (647) 550-4220.
On older natural draft units, a pilot that won’t stay lit is typically a thermocouple failure — a $150–200 repair that makes sense on a unit under 7 years old. On a unit over 8 years old in London Ontario’s water conditions, the repair cost is better put toward a new Rheem or Navien. Call (647) 550-4220 for a same-day assessment.
Rheem Gas Tank or Navien Tankless.
Your Situation Determines the Right Choice.
Abdullah recommends based on your actual household, budget, and long-term goals — not on which unit has the higher margin. Here is an honest breakdown.
| Feature | Rheem Gas Tank | Navien NPE-S Tankless |
|---|---|---|
| Starting price all-in (London Ontario) | $2,700 | $3,500 |
| Hot water supply | 40 or 50 gallons stored | Endless — on demand |
| Efficiency | 0.67–0.82 UEF | 0.97 UEF |
| Expected lifespan in London Ontario | 10–12 years | 20–25 years |
| Gas bill savings vs old tank | Modest (efficiency similar) | 20–30%/year |
| Installation time | 2–3 hours | 3–5 hours |
| Venting | 2" PVC power vent | 2–3" PVC condensing |
| Best for | Budget priority, simple replacement, modest demand | Rental replacement, high demand, long-term value |

Rheem is Hawana’s primary gas tank recommendation in London Ontario. The Performance series power vent units have a strong track record in Ontario’s climate and water conditions. Power vent means no chimney is required — the fan exhausts gases through 2-inch PVC horizontally to the exterior, making installation straightforward in any part of the home. GSW (Canadian brand) is also available and performs well in London Ontario water conditions.
| Model | Best For | Recovery | Price |
|---|---|---|---|
| 40-Gallon | 1–3 people, 1–2 baths | Standard | $2,700 |
| 50-Gallon | 3–5 people, high demand | Faster | $2,900 |

If you’re paying $35–60/month for an Enercare or Reliance rental, the Navien pays for itself in 5–8 years through eliminated rental fees alone — before energy savings are counted. Endless hot water, 0.97 UEF efficiency, 20+ year lifespan. Rinnai RX also available at the same price. The detailed Navien vs Rinnai comparison and all technical installation details are on the dedicated page.
| Navien Model | Best For | Price |
|---|---|---|
| NPE-150S2 | 1–2 baths • 1–3 people | $3,500 |
| NPE-180S2 | 3+ baths • High demand | $3,650 |
If You’re Renting a Water Heater
This Page Could Save You Thousands
Choose Navien tankless instead of a Rheem tank ($3,500 vs $2,700)? Against a $42/month rental, the Navien breaks even in 7 years through rental savings alone — and generates 20–30% lower gas bills every year for a 20+ year lifespan. Over 20 years: renting costs $10,080. Owning a Navien costs $3,500. Call (647) 550-4220 to stop renting.

Water Heater Failed?
Same-Day Replacement Available London Ontario
Hawana provides same-day gas water heater replacement in London Ontario. A leaking tank, no hot water, or a failed pilot that won’t relight — call (647) 550-4220 immediately. Abdullah assesses the situation and provides a repair-vs-replace recommendation. If replacement is needed and stock is available, the new Rheem is installed the same day. Zero after-hours surcharge — the $175 service call is the same at 8 PM on a Sunday as it is at 10 AM on a Tuesday.

Understanding Your
London Ontario Water Heater Options
The right water heater for your London Ontario home depends on what you currently have and what your home’s venting setup can accommodate. Abdullah confirms all of this at the free quote visit.
- Power vent (most common for new installations): electric fan exhausts gases through 2" PVC horizontally to the exterior. No chimney needed. Can be installed anywhere in the home. Requires a nearby electrical outlet. Rheem Performance Power Vent from $2,700.
- Natural draft (chimney required): hot exhaust gases rise naturally through a B-vent pipe to the chimney. If your home still uses a chimney for the water heater, replacing with a power vent may involve capping the chimney connection. Abdullah assesses the venting change at the quote visit.
- Direct vent (sealed combustion): draws combustion air from outside through a dedicated intake pipe alongside the exhaust vent. Common in tight spaces. Available in Rheem series.
- Tankless condensing (recommended for rental replacements): Navien NPE-S and Rinnai RX vent through 2–3" PVC. Endless hot water. 0.97 UEF. See the full tankless installation page →
How Water Heater Installation Works
5 Steps — London Ontario
Abdullah confirms: existing tank size (40 or 50 gallon), venting type (power vent, natural draft, or direct vent), gas line condition, and location. He recommends the right Rheem size for your household demand — not the largest available. For rental replacements, rental pickup is coordinated same-day. Written all-in quote same visit: unit + labour + gas line + power vent PVC + TSSA permit + old unit removal. Invoice = quote.

Existing tank drained completely through the drain valve. Gas supply valve closed at the unit. Cold water inlet and hot water outlet disconnected. Old tank removed from the home and disposed of. For Enercare/Reliance rentals: rental company pickup and Hawana installation scheduled for the same morning — no gap in hot water service, no cold nights between.

New Rheem placed on drip pan (required per Ontario Building Code). Gas line connected with proper fittings. Cold water inlet connected. Hot water outlet connected. Pressure relief valve (PRV) installed and discharge pipe run to within 6 inches of the floor — a code requirement that is sometimes skipped on improper installations. Temperature expansion tank installed if required by the home’s water supply configuration.

Power vent fan connected and 2-inch PVC exhaust vent routed to the exterior wall with correct slope (minimum 1/4" per foot downward toward the exterior to prevent condensation poolback). Exterior termination cap installed with proper clearances from windows, doors, and building openings per Ontario Building Code. For natural draft conversions: existing B-vent connection capped and power vent PVC run.

Gas turned on, pilot or electronic ignition activated. Thermostat set to 49°C — the Health Canada recommended setting for London Ontario homes that balances scalding prevention with Legionella bacteria inhibition. TSSA inspector performs permit inspection (same day or next business day). Hot water output confirmed at kitchen and bathroom fixtures. Power vent fan operation confirmed. Invoice matches written quote exactly.

Every Water Heater Installation
Is Abdullah Personally
Abdullah Ghzail founded Hawana HVAC Solutions in London Ontario in 2018. Every water heater installation is Abdullah personally — no subcontractors, no apprentices on the gas line or permit. He has replaced Enercare and Reliance rentals across every London Ontario neighbourhood, installed Rheem Power Vent units same-day for emergency failures, and converted hundreds of London Ontario homes from chimney-vented natural draft units to power vent PVC configurations.
His approach to repair-vs-replace is straightforward: if the tank is under 7 years old, he recommends repair if the repair is cost-effective; if it’s over 8 years old in London Ontario’s water, he recommends replacement — and he explains why, so you can make the decision. He does not recommend the more expensive option to increase the invoice. The written quote is the invoice.
