How a Heat Pump Water Heater Works — COP 3.0–4.0 Explained
The key to understanding a heat pump water heater is the refrigerant cycle. It moves heat rather than generating it — which is why it can deliver 3 to 4 times more energy than it consumes.
Moving Heat vs Generating Heat
A conventional electric water heater element generates heat by passing electricity through a resistive wire — 1 unit of electricity in, 1 unit of heat out. COP = 1.0. A heat pump water heater uses a compressor and refrigerant to extract heat that already exists in the surrounding basement air, concentrate it, and transfer it into the water tank. Because it is moving existing heat rather than generating new heat, it delivers 3 to 4 units of thermal energy for every 1 unit of electrical energy consumed. COP = 3.0 to 4.0.
The Refrigerant Cycle — Step by Step
Warm basement air is drawn across the evaporator coil by a fan. The refrigerant inside the coil absorbs heat from the air and evaporates into a gas. The compressor pressurises the refrigerant gas, raising its temperature significantly. The hot, pressurised refrigerant gas passes through a condenser coil wrapped around the water tank, releasing its heat into the water. The refrigerant condenses back into a liquid, expands through an expansion valve, and the cycle repeats. The result: the basement air is cooled and dried slightly; the water tank is heated efficiently.
Why Ontario Basements Are Ideal
Most Ontario conditioned basements maintain 10 to 18 degrees Celsius year-round — even in January. At 15°C basement air temperature, a Rheem ProTerra operates at approximately COP 3.5. At 20°C (typical summer basement temperature), COP reaches 4.0. This is far superior to a cold-climate space heating heat pump that must extract heat from outdoor air at minus 20°C in an Ontario winter. The indoor basement heat source is stable, consistent, and warm enough to maintain high efficiency all year.
Hybrid Mode — The Backup Electric Element
Every heat pump water heater includes a conventional electric resistance element as a backup — this is what makes it a "hybrid" water heater. In peak demand situations (the whole family showers in rapid succession), the unit automatically engages the electric backup element alongside the heat pump to ensure hot water supply is maintained. The heat pump mode handles roughly 80 to 90 percent of all heating in normal usage, keeping operating costs low. The backup element handles the rest.

Heat Pump Water Heater Space Requirements — Ontario Basement Guide
A HPWH needs more space than a conventional tank because it draws and exhausts air. Hawana assesses your specific basement at the estimate visit. Here is what we look for.
Ceiling Height: 7 ft+ Required
Most heat pump water heaters are 60 to 70 inches (152–178 cm) tall — taller than a conventional tank. You need a minimum 7-foot (213 cm) ceiling clearance plus 6 inches above the unit for the evaporator fan intake. Standard London Ontario basement ceiling heights of 7 to 8 feet are typically adequate. Lower mechanical crawl spaces are not suitable.
Air Volume: 700–1,000 sq ft Recommended
The heat pump draws air from the surrounding space. In a small enclosed room (under 400 sq ft), the unit rapidly depletes the heat in the air and loses efficiency. An open-concept basement of 700+ square feet, or a mechanical room with louvred doors to a larger space, is ideal. Alternatively, duct kits can draw exterior air — Hawana will recommend the right approach for your layout.
Temperature: 7°C–43°C Year-Round
A conditioned London Ontario basement — heated by the furnace in winter — typically stays between 10 and 18 degrees Celsius all year. This is the sweet spot for HPWH efficiency. The unit will operate (with reduced efficiency) down to 7°C. Below 7°C, it switches to electric-only mode. A heated, insulated basement is ideal.
Enclosed Cold Room: Use With Caution
A small, unheated cold room under the front porch — common in London Ontario older homes — drops below 7°C in winter. Installing a HPWH here requires a duct kit to draw air from a warmer adjacent space, or the unit runs in electric-only mode in winter. Hawana assesses and recommends the duct configuration at the estimate visit.
Adjacent to Bedroom: Noise Consideration
A HPWH operates at 45 to 55 dB during heat pump cycles — similar to a quiet dishwasher. In a mechanical room with a door, this is inaudible in living spaces. Directly adjacent to a bedroom on a shared wall, some homeowners notice the fan noise. Hawana discusses placement options and insulation solutions at the estimate visit.
Unheated Detached Garage: Not Suitable
An unheated garage in Ontario drops below 7°C for months in winter. A HPWH here would run in electric resistance mode through winter — eliminating the efficiency advantage. A gas tankless (from $3,500) or a well-insulated electric tank is a better choice for an unheated garage water heater application.
Hawana's basement assessment: Every heat pump water heater estimate includes a free on-site assessment of your basement — ceiling height, air volume, winter temperature range, proximity to bedrooms, and electrical service capacity (HPWH units typically draw 15 amps on a 240-volt dedicated circuit). If your basement is marginal, Hawana presents both the HPWH option and the most suitable alternative at the same visit with published pricing for each. Call (647) 550-4220.
Heat Pump Water Heater vs Tankless vs Tank — Complete Ontario 2026 Comparison
Three technologies, three situations. Hawana quotes all three at the same estimate visit so you can make an informed comparison. Here is the honest data.
| Feature | ⚡ Heat Pump WH (HPWH) | 💧 Gas Tankless | 🐥 Gas Tank | ⚡ Electric Tank |
|---|---|---|---|---|
| Hawana installed price | From $4,600 | From $3,500 | From $2,700 | From $2,500 |
| Greener Homes grant | $1,000 (qualifying) | No | No | No |
| Effective net cost | ~$3,600 (after grant) | $3,500 | $2,700 | $2,500 |
| Energy efficiency | COP 3.0–4.0 | 0.93–0.97 UEF | 0.62–0.70 EF | COP 1.0 |

| Endless hot water | Large tank — nearly | Yes — on demand | No — tank capacity | No — tank capacity |
| Space requirements | 700+ sq ft · 7 ft ceiling | Minimal — wall-mounted | Minimal | Minimal |
| Noise level | 45–55 dB (fan cycles) | Silent standby | Silent | Silent |
| Lifespan | 13–15 years | 15–20 years | 8–12 years | 8–12 years |
| Monthly operating cost* | ~$25–$35/month | ~$20–$35/month | ~$40–$60/month | ~$60–$90/month |
| Best for | All-electric homes; high electricity bills; grant-seekers | Homes on gas; large families; tight space | Gas homes; lowest upfront cost | Lowest upfront; small household |
*Estimated monthly operating cost based on London Ontario average household hot water usage. Actual costs vary by household size, usage patterns, and utility rates.
Bottom line for all-electric Ontario homes: If your home has no natural gas supply, the heat pump water heater from $4,600 (net ~$3,600 after the $1,000 Greener Homes grant) is dramatically more cost-effective to operate than a conventional electric tank. The monthly energy savings of $30–$55 versus an electric tank typically result in full payback within 3 to 5 years, after which all savings are pure reduction in electricity cost. Hawana presents the full 10-year cost-of-ownership comparison at every estimate.

"Rheem ProTerra 50 gallon in our London Ontario all-electric home — no gas supply line. Electric bill on the old tank was significant. Hawana explained the heat pump clearly: it draws heat from our basement air (conditioned at around 15 degrees in winter) and that's why it's three times more efficient. Published price from $4,600 before I called. The $1,000 Greener Homes grant handled entirely by Hawana — cheque arrived in eight weeks. Electric bills dropped noticeably. The unit runs at about the same level as our refrigerator. No rental, outright. Invoice matched the written quote."
"AO Smith Voltex 80 gallon — family of six, no natural gas service. We looked at gas tankless but the gas line installation would have been an additional cost. Hawana assessed our basement: 900 square feet of open mechanical space, consistent 14-degree temperature in winter — confirmed the Voltex 80 would perform well. The technician explained the space requirements clearly. Greener Homes grant handled by Hawana after installation. The 80-gallon capacity means we essentially never run out. No rental. Invoice matched."
"Deciding between Rheem ProTerra heat pump WH and an electric tankless. No gas at the property. Hawana quoted both: the HPWH from $4,600 with the $1,000 Greener Homes grant making the net cost approximately $3,600; and electric tankless which requires significant panel amperage upgrade. HPWH was the clear winner for an all-electric home. Rheem ProTerra 50 gallon installed. Noise level in the mechanical room is noticeable but completely acceptable. Electric bill savings were immediate. Grant handled by Hawana. No rental. Invoice matched."
