Air-to-water pool heat pump with a nominal capacity of 65,000 BTU/h from TTI FAB, a manufacturer based in Longueuil. This is the Stratos 65 Inverter, the only 65,000 BTU Stratos in the TTI 2026-2027 catalogue: its variable-speed compressor offers three heating modes, from high mode, which delivers maximum output, to silent mode, which uses the least electricity for each unit of heat produced. Titanium heat exchanger compatible with saltwater pools (chlorinator installed after the heat pump), 240 V power supply and a parts and labour warranty of 6 years in Quebec.
Highlights
Description
A pool heat pump burns no fuel: it captures heat from the outside air. The fan moves the air across a coil filled with circulating refrigerant, the compressor concentrates that heat, then the titanium heat exchanger transfers it to the pool water flowing through it. That is why it delivers several units of heat for each unit of electricity consumed (the COP), and why its output drops as the air gets cooler: according to TTI, in high mode the Stratos 65 Inverter goes from 60,300 BTU/h with air at 26.7 °C to 41,000 BTU/h with air at 10 °C (water at 26.7 °C and 63% humidity in both cases). It is designed to heat pool water; TTI publishes no cooling capacity for this model.
What sets this model apart is its variable-speed inverter compressor. A fixed-speed model, such as the Stratos-50, always heats at the same output, cycling on and off. The Stratos 65 Inverter offers three modes: high mode delivers maximum output, useful for raising the water temperature, while normal and silent modes heat more slowly, but with a better COP, meaning less electricity for each unit of heat produced. The control panel includes a timer.
In the Stratos range offered by AFI, the Stratos 65 Inverter is the mid-range model: it sits between the Stratos-50 (50,000 BTU nominal, fixed speed) and the Stratos-80 (80,000 BTU nominal), designed for the largest pools. The right choice among the three depends mainly on the pool's volume, the target temperature, its exposure to wind and whether it has a cover: email us for sizing. TTI FAB states that its heat pumps are designed and manufactured in Quebec.
Output and efficiency according to TTI
| Air 26.7 °C, water 26.7 °C, humidity 80% | High: 64,000 BTU/h, COP 5.5 Normal: 48,800 BTU/h, COP 7.4 Silent: 26,000 BTU/h, COP 10.5 |
|---|---|
| Air 26.7 °C, water 26.7 °C, humidity 63% | High: 60,300 BTU/h, COP 5.3 Normal: 43,300 BTU/h, COP 6.8 Silent: 24,000 BTU/h, COP 9.0 |
| Air 10 °C, water 26.7 °C, humidity 63% | High: 41,000 BTU/h, COP 3.8 Normal: 27,500 BTU/h, COP 4.4 Silent: 13,800 BTU/h, COP 5.0 |
Manufacturer's values (Stratos Inverter 2027 spec sheet and 2026 manual), calculated to the AHRI 1160 standard according to TTI. The 26.7 °C corresponds to the 80 °F in the TTI documents. The COP (coefficient of performance) is the ratio between the heat delivered to the water and the electricity consumed. The 65,000 BTU corresponds to the model designation: the highest output published by TTI is 64,000 BTU/h.

These specifications are those of the Stratos 65 Inverter, the only 65,000 BTU Stratos in the TTI 2026-2027 catalogue. The exact electrical requirements are shown on the unit's nameplate: that is what your electrician must go by. TTI asks you to register the warranty online.
Installation
| Electrical | Dedicated 240 V circuit, connected by a master electrician in accordance with applicable codes, with grounding. The breaker is installed near the unit, in an accessible location; its rating is shown on the nameplate. |
|---|---|
| Location | Outdoors only: never in a shed, garage or basement. Not under a roof (risk of being buried under snow, or too much water without a gutter) or near a sprinkler. Keep direct sunlight off the controller: the display becomes hard to read. |
| Clearances | 60 cm (2 ft) in front of the evaporator coil; 120 cm (4 ft) in front of the fan, the service panel and the other sides. |
| Base | Flat, firm and level surface, preferably a concrete slab. The unit produces condensation water: make sure there is good drainage around it. |
| Plumbing connection | 1½ in. fittings. A set of valves (bypass) must allow the heat pump to be isolated and the flow to be adjusted; the bypass valve stays closed during operation. With a pump of 2 HP or more, TTI requires an adjustable automatic bypass valve. |
| Chlorinator and chemicals | Any chlorine or bromine feeder and any salt chlorinator must be installed after the heat pump. Otherwise, according to TTI, the heat pump warranty is void. |
| Flow and pressure | 57 to 170 L/min (15 to 45 US gal/min), 12 to 15 PSI, 30 PSI maximum. Outside these values, damage is not covered by the warranty. |
| Piping | 10 m (about 33 ft) maximum between the pool and the unit; insulate the pipes. |
| Start-up | Start the filtration pump before the heat pump. The fan runs for 3 minutes before the compressor starts. |
| Large pools | Two units can be connected in parallel, at least 2 ft (about 60 cm) apart. |
TTI specifies that the unit must be installed and serviced by a professional technician, and its limited warranty excludes damage caused by improper installation. Email us before ordering if you have any doubt about your pump's flow rate or your electrical panel's capacity.
Winterizing
In Quebec, drain the heat pump before the first frost, at the latest when you close the pool (AFI tip): water left in the heat exchanger can freeze, and freeze damage is not covered by the warranty. Here are the steps from the TTI manual:
| 1. Turn off the unit | Switch off the heat pump. |
|---|---|
| 2. Cut the power | Switch off the breaker and close the valves. |
| 3. Disconnect the plumbing | Unscrew the water inlet and outlet fittings. |
| 4. Drain the heat exchanger | Rinse it with tap water, then clear out the remaining water with compressed air or a wet/dry vacuum. |
| 5. Protect the unit | If it stays outside all winter, cover it with a waterproof protective tarp. |
In spring: check and adjust the water quality, make sure the breaker is switched off, set the unit level and reconnect the plumbing, clean the filter and check the water return, then switch the breaker back on. During the season, keep the coil free of leaves and debris; clean it with a mild cleaner and rinse it with a garden hose at low pressure, without solvent or gasoline.
