What about Heat Pumps? The Case for Commercial Heat Pumps in Your Facility
Why Alberta's commercial operators are replacing gas-fired HVAC with engineered heat pump systems — and what the performance data actually shows about cold-climate operation.
The conventional wisdom that heat pumps don't work in Alberta is outdated by about a decade. Modern cold-climate systems operate efficiently at -30°C and below. The question for commercial operators isn't whether they work. It's whether the engineering is right for your facility.
🌡️ What a Heat Pump Actually Does
A heat pump doesn't generate heat by burning fuel. It moves heat that already exists in the outdoor air (or the ground, in a geothermal system) and transfers it indoors. In summer, the process reverses to provide cooling.
Because it's moving heat rather than creating it through combustion, a well-designed system delivers 2.5 to 4 units of thermal energy for every unit of electrical energy consumed. That ratio — the Coefficient of Performance, or COP — is what makes heat pumps financially compelling compared to gas heating, especially as Alberta's carbon levy on natural gas continues to climb.
The efficiency advantage is not marginal. It is structural. And in a commercial facility with a substantial heating load, that structural advantage compounds significantly over an asset's operating life.
🏢 Why Commercial Buildings Are a Strong Fit
The commercial case for heat pumps is different from residential — and in most respects stronger:
- Higher load means bigger absolute savings. A commercial building with a $15,000 monthly gas bill has more to gain from switching to an efficient electric heating system than a home with a $300 bill. The COP advantage applies at scale.
- Heating and cooling in one system. Most commercial facilities need both. A heat pump replaces two separate mechanical systems — furnace and air conditioning — with one integrated unit. That's one maintenance contract, one service relationship, one capital item on the balance sheet.
- Carbon pricing trajectory. Alberta's carbon levy applies to natural gas consumption. That levy is expected to continue increasing over the coming years. Every efficiency improvement in your HVAC system reduces exposure to that escalating cost.
- Electrical rate arbitrage ahead. When time-of-use pricing arrives in Alberta, heat pumps paired with thermal storage (buffer tanks, hydronic loops) can shift heating loads to off-peak hours — a capability gas systems don't have.
🏭 Industry Applications
| Facility Type | Heat Pump Application | Key Benefit |
|---|---|---|
| Office Buildings | Air-to-air or air-to-water for heating/cooling | Single system replaces split HVAC, lower opex |
| Food & Beverage | Process heating, space conditioning, hot water | Carbon levy reduction, COP 3–4x vs. gas |
| Warehousing | Space heating for large-volume facilities | Reduces propane/gas spend on warehouse heat |
| Ice Rinks | Building HVAC separate from refrigeration plant | Cuts gas use for lobby, dressing room, office heat |
| Retail & Commercial | Rooftop heat pump units replacing RTUs | Direct replacement of aging gas rooftop units |
| Private Schools | Central air-to-water hydronic systems | Uniform comfort, reduced gas, sustainability optics |
❄️ Cold Climate Performance: What the Data Shows
One of our engineers fully electrified his Edmonton home using a cold-climate air-to-water heat pump — removing the gas meter entirely. The system operates on a standard 100A panel, integrates with solar PV, and includes real-time monitoring via a custom dashboard that logs temperature, energy consumption, and COP continuously.
Key performance findings from that installation:
- The system maintains full heating output down to approximately -25°C to -30°C, covering the vast majority of Alberta's heating season without backup
- COP values averaging 2.5 to 3.5 across the heating season, compared to roughly 0.9 for a gas furnace on an equivalent energy basis
- Domestic hot water preheating integrated into the same loop, further improving overall system efficiency
- Variable speed compressor and VFD fan coil maintain room temperature within 0.5°C of setpoint, compared to 3–4°C swings from the previous oversized gas furnace
The installation described above was designed, monitored, and documented by one of our P.Eng.-credentialed engineers. It runs fully electric in one of Canada's coldest major cities. The performance data is real, the monitoring is continuous, and the conclusions are based on measured results — not manufacturer specifications.
When we tell you a heat pump works in Alberta winters, we're not repeating a marketing claim. We're reporting on a system one of our own engineers lives in.
⚙️ Air-to-Air vs. Air-to-Water vs. Geothermal: Choosing the Right System
Not all heat pumps are the same. The right configuration depends on your facility's existing infrastructure, load profile, and long-term plans.
Air-to-Air
The most common configuration. Integrates directly with existing ductwork or air handling units. Lower capital cost, faster installation, suitable for most commercial spaces with existing forced-air infrastructure. Best where the existing distribution system is serviceable and the primary goal is replacing the gas heating source.
Air-to-Water (Hydronic)
Uses a refrigerant loop to heat water, which then distributes heat through radiant floors, fan coils, or baseboard units. Higher capital cost and installation complexity than air-to-air, but delivers superior comfort, lower distribution energy losses, and integrates naturally with thermal storage. The preferred configuration for new builds or major retrofits with high heating loads.
Ground Source (Geothermal)
Exchanges heat with the ground rather than the outdoor air. Delivers higher and more stable COP year-round because ground temperatures remain consistent regardless of ambient conditions. Highest capital cost due to the ground loop installation, but lowest operating cost over the system's life. Covered in depth in the next post in this series.
🔧 The Engineering Requirement
Commercial heat pump installations require proper load calculations — Manual J or equivalent — to size the equipment correctly for the building's actual thermal demand. Oversized equipment short-cycles, reducing efficiency and comfort. Undersized equipment can't maintain setpoints during peak cold.
This is not a calculation that should be done by a salesperson with a rule of thumb. It requires a proper building energy model, which is precisely what Intricate Renewables produces before sizing any commercial heat pump system. Every commercial project involves a P.Eng. We do not size commercial HVAC systems without one.
Heat pumps are most powerful when integrated with solar PV. When the sun is producing, the heat pump runs on energy you generated yourself — compounding the efficiency advantage with eliminated fuel cost. We design these systems as integrated wholes, not separate installs.
- Existing infrastructure matters. The right heat pump configuration depends heavily on what you already have. Ductwork condition, electrical service capacity, and mechanical room space all affect the design. A proper site assessment is the starting point.
- Carbon levy rates change. The financial case includes avoided carbon levy on natural gas. That calculation depends on levy rates that are subject to federal and provincial policy. We model the current rate and flag the sensitivity.
- We are not HVAC contractors. Intricate Renewables designs and installs heat pump systems as integrated energy systems. We work with mechanical trades where required and manage the full project. For complex existing mechanical systems, collaboration with your current HVAC service provider may be appropriate.
The heating system in a commercial building is one of its largest operating cost line items. It's also one of the most replaceable with modern technology. A properly engineered heat pump system reduces that cost structurally, permanently, and in a way that compounds as energy prices rise.
We've designed and operated these systems in Alberta conditions. We know what works, what the data shows, and how to build the financial case for your specific facility.
