Replace Your Enercare Rental
With a Navien You Own
How rental replacement works: Hawana installs your Navien. After installation, call Enercare or Reliance to cancel. They pick up the old rental unit. Your monthly charge ends that day. Hawana provides all documentation confirming the replacement. Same-day installation available. Most rental cancellations are fee-free after the contracted term — check your agreement.
London Ontario Hard Water
and Your Navien Tankless
London Ontario municipal water is moderately hard — approximately 120–180 mg/L of calcium and magnesium (7–10 gpg). This is within the typical range for Southwestern Ontario but means tankless water heater heat exchangers will accumulate mineral scale over time.
- →Annual descaling recommended (vinegar flush)
- →Neglected scale reduces efficiency 15–25%
- →Scale buildup can shorten lifespan significantly
- →Navien's self-diagnostics alert to flow issues early
A Navien descaling service involves circulating a descaling solution through the heat exchanger for 30–45 minutes. This removes mineral deposits before they reduce efficiency or cause premature failure. Hawana recommends this annually for London Ontario's water conditions.
- ✓Navien maintains full efficiency rating
- ✓Heat exchanger warranty stays valid
- ✓20+ year realistic lifespan achievable
- ✓Hawana's Premium Care Plan includes this check
Tankless Installation Process
London Ontario
Call (647) 550-4220. Abdullah assesses household size, simultaneous hot water demand, existing gas line capacity, and any venting constraints. Recommends the right BTU and brand for your actual usage — not the most expensive option.
Choose Navien $3,500, Noritz $3,600, or Rinnai $3,800. Written quote provided. That price is the invoice. All-inclusive: unit, all labour, gas line connection (and upsizing if needed), PVC or direct-vent flue, water connections, old unit removed free.
TSSA-certified technician installs in 3–5 hours same-day. Gas line inspected and upsized if needed for the tankless unit's higher BTU demand. Venting installed. System commissioned and fully tested — hot water confirmed flowing before leaving. No cold showers tonight.
Complete installation documentation provided — model, serial, TSSA certificate, signed invoice. If replacing a rental: cancel Enercare or Reliance after installation — monthly charge stops that day. Schedule annual descaling to protect your Navien in London's moderately hard water.
Note on gas line sizing: Tankless water heaters typically require a larger gas line than the tank unit they replace (150,000–200,000 BTU vs 40,000 BTU for a tank). Hawana inspects your existing gas line and includes any necessary upsizing in the written quote. No surprise charges — it's all confirmed before installation begins.
The Tankless Specialists
Who Don't Do Rentals
Navien $3,500, Noritz $3,600, Rinnai $3,800 — published here before you call. No competitor in London Ontario posts these numbers. What Hawana quotes is what the invoice says.
Enercare and Reliance charge $40+/month for a unit worth $3,500 — forever. Hawana installs outright ownership. We help London Ontario homeowners escape rental contracts. We never create new ones.
Tankless water heater installation involves gas line work — sizing, connection, and pressure testing. This requires TSSA certification under Ontario law. Abdullah holds it for natural gas and LP/propane.
London Ontario's moderately hard water (120–180 mg/L) affects tankless longevity. Hawana factors this into every recommendation — right unit, right maintenance plan, right descaling schedule. Not every installer considers this.
