Tankless water heaters heat water only when you need it, not all day like traditional tanks. That means:
📏 System Sizing & Recommendations
We size your system based on bathrooms, fixture flow rates, and simultaneous demand. We won’t oversell or underpower your home — just the right fit.
🧰 Professional Installation
Includes venting, gas line upgrades (if needed), water softening prep (where applicable), and pressure regulation.
We install trusted brands — and we do it clean, to code, and right the first time.
🛠️ Tankless Water Heater Repairs
From ignition issues to scale buildup and error codes, we troubleshoot and repair most major tankless brands — even if we didn’t install it.
💧 Water Softener Compatibility Checks
Hard water shortens the life of tankless units. We’ll test your water and recommend filtration or softening where needed — especially in Calgary.
🔋 Annual Service & Flushes
We offer maintenance to descale your tankless unit and keep it running efficiently. Neglecting this step is the #1 cause of early failure.
With proper maintenance, they can last 15–20 years — longer than most standard tanks. Annual flushing is key, especially in Calgary’s hard water conditions.
No — tankless systems provide endless hot water. But they can be overwhelmed if undersized. We’ll make sure you get the right size for your household.
Yes — they only heat water when needed, unlike tanks that heat 24/7. Over time, this can lead to significant energy savings.
We highly recommend it in Calgary. Hard water can cause scale buildup and reduce efficiency or damage the heat exchanger over time.
Yes — we work on most major brands and can flush, repair, or diagnose tankless units even if we didn’t do the original install.
