Hot Water When You Need It — Tank, Tankless, and Everything Between
Water heater installation, repair, and replacement for Calgary homes. We service gas tank heaters, tankless condensing units (Navien, Rinnai), and electric storage tanks. Same-day emergency service available.
Which Water Heater Is Right for Your Calgary Home?
Both tank and tankless water heaters work well in Calgary — the choice depends on your household's hot water usage patterns, available space, and budget. We give you a straight comparison at the quote, not a push toward the higher-margin unit.
Gas Storage Tank
Heats and stores 40–60 gallons of hot water ready on demand. Lower installation cost, simple service, wide parts availability. Standby heat loss reduces efficiency. Tank life: 10–15 years. Good choice for homes with lower peak demand or where installation cost is the priority.
- Lower upfront cost
- Simple to service anywhere
- Works during power outages (gas)
Condensing Tankless (Navien / Rinnai)
Heats water on demand — no standby losses, unlimited hot water. 96%+ efficiency vs 60–80% for standard tanks. Higher installation cost offset by lower monthly gas bills. Requires condensate drain. Excellent for high-demand households, vacation properties, or homes with space constraints. Navien NPE-A2 and Rinnai RXP series are our recommended models for Calgary.
- Unlimited hot water
- 96%+ efficiency
- 20+ year lifespan on major brands
How Can You Know If Your Water Heater Is About to Fail?
A water heater is like any other appliance in that it's built to last a certain amount of time. Most water heaters are built to last 15–20 years, and after that, anything can happen. Fortunately, most water heaters give signs signaling they're about to fail. Here's what to look out for.
Cloudy Water
Gurgling, Banging Sounds
Lukewarm Water
Rust Around the Tank
Water Leaking
All of these are signs that your water heater is in danger of failing, and if you notice any, you must call a hot water maintenance company right away to fix the problem.
When Should I Replace My Hot Water Heater?
Your water heater is made to last a long time, but sooner or later, you'll have to consider replacing it. Here are a few things to think about when weighing replacement.
How Old Is It?
A water heater that's over 20 years old is coming up on the end of its life, and it's time to think about getting a new hot water tank installation.
How Expensive Are Your Energy Bills?
If you've seen a sudden increase in your energy bills, it could be due to a failing water heater. The extra money you're spending in bills could be going toward a new water heater instead.
If you're not sure how old your water heater is, or would like an assessment of its health, call a Calgary water heater replacement company and ask them for help.
Can Water Heater Maintenance Extend the Life of Your Water Heater?
Even though most water heaters have a lifespan of about 20 years, the fact is that with regular maintenance, you can extend the lifespan by a few years. Experts recommend that you regularly flush the tank and replace your anode rod if it's corroded. Also, it's recommended you schedule regular hot water heater maintenance with a reputable plumbing company.

Water Heater Questions
How do I know when my tank water heater needs replacement vs repair?
Tank age is the key factor. If the tank is 8–10 years old and you're facing a significant repair (heat exchanger, thermocouple, major leak), replacement is usually the better investment — a new tank has a 10–15 year life ahead of it, the old one has 5 or fewer. If the tank is under 7 years old and the failure is a single component (thermocouple, element, anode rod), repair makes sense. We give you both options and real costs at the diagnostic visit.
How much does a tankless water heater cost to install in Calgary?
A condensing tankless installation (unit + installation labour + condensate drain + venting) typically runs $3,500–$5,500 depending on the unit size and complexity of the installation. The efficiency savings on a typical Calgary household reduce gas bills by $200–$400 per year compared to a standard storage tank — a 10–15 year payback on the premium. We provide a detailed quote before any work starts.
My hot water is rusty or smells like rotten eggs — what does that mean?
Rusty water from a tank heater typically means the anode rod (a sacrificial magnesium or aluminum rod that prevents tank corrosion) has been depleted — a common cause of premature tank failure. Replacing the anode rod every 5–7 years significantly extends tank life. A rotten-egg (sulphur) smell usually comes from bacterial growth in a tank set too low or from a depleted anode rod reacting with sulphur in Calgary's water supply. We can diagnose and address both on a service call.
