The Stratos-80 is a pool heat pump rated at 80,000 BTU/h by TTI, the largest of the three Stratos models offered by AFI. From Quebec manufacturer TTI FAB, based in Longueuil, it heats the water of in-ground and above-ground pools with a titanium heat exchanger, and is compatible with a saltwater pool provided the salt chlorine generator's outlet is placed after the heat pump. It runs on a 240 V circuit, uses 1½ in. water connections, defrosts automatically and, in Quebec, is covered by a TTI warranty of 6 years on parts and labour for a purchase made on or after October 5, 2026.

Automatic defrostThe unit handles its own defrosting, with no action required on your part.
Built-in protectionsHigh or low water pressure detection, automatic shutdown when it is too cold and a delay of 3 minutes before the compressor starts.
Automatic restartAfter a power outage, the heat pump restarts on its own.
Quebec brandTTI FAB is based in Longueuil. According to TTI, its Stratos heat pumps are designed and manufactured in Quebec.
6-year warranty in QuebecParts and labour, from the delivery date, for a new heat pump purchased on or after October 5, 2026, according to TTI.

Description

A pool heat pump does not create heat: it draws it from the outside air. Its fan moves air over a coil carrying refrigerant, the compressor concentrates that heat, then the titanium heat exchanger transfers it to the pool water flowing through the unit. According to TTI's data, it thus delivers several times more heat than the electricity it consumes, but its efficiency drops markedly as the air gets cooler: it performs best in mild weather, with a cover on the pool at night, as TTI recommends. The Stratos only heats: it has no cooling mode.

The Stratos-80 is the largest of the three Stratos models offered by AFI, whose nominal capacities are 50,000, 65,000 and 80,000 BTU/h. For the same pool, a higher capacity raises the water temperature faster: this is the model to consider for a large in-ground pool, a pool exposed to wind or extended swimming in spring and September. For a very large pool, TTI also provides for connecting two units in parallel.

Like the other Stratos models, it uses 1½ in. connections, the same water flow range and a dedicated 240 V circuit. Its breaker rating is shown on the nameplate: we confirm it for you before purchase so your electrician can plan the connection. TTI states that its performance figures (BTU and COP) are calculated according to the AHRI 1160 test standard.

Installation

ElectricalDedicated 240 V circuit, connected by a master electrician in accordance with applicable codes, with grounding. The breaker must be installed near the unit, in an accessible location; its rating is shown on the nameplate.
LocationOutdoors only, never in a shed, garage or basement. Not under a roof (risk of being buried under snow, or too much water without an eavestrough), away from automatic sprinklers, with the control panel out of direct sunlight.
Clearances60 cm (2 ft) in front of the evaporator coil; 120 cm (4 ft) in front of the other sides, the fan and the service panel.
BaseFlat, firm and level surface, preferably a concrete slab. The unit produces condensation: allow for water to drain away around it.
Plumbing1½ in. connections. According to the basic plumbing diagram in the TTI manual, the heat pump connects after the pump and filter, and before the chlorinator or salt chlorine generator. A set of bypass valves must make it possible to isolate the heat pump and adjust the flow so that it stays between 57 and 170 L/min. With a pump of 2 HP or more, TTI requires an adjustable automatic bypass valve.
Pipe lengthConnecting pipes of 10 m (33 ft) or less between the pool and the unit, insulated to limit heat loss.
ChemicalsThe outlet of the chlorinator, brominator or salt chlorine generator must be after the heat pump. Otherwise, according to TTI, the warranty is void.
Flow and pressure57 to 170 L/min (15 to 45 US gal/min), pressure of 12 to 15 PSI, 30 PSI (2 bar) maximum.
Two unitsParallel connection possible for a large pool, with at least 60 cm (2 ft) between the units.
Start-upStart the filtration pump before the heat pump. The fan runs for 3 minutes before the compressor starts.

According to TTI, the unit must be installed and serviced by a professional technician. The TTI limited warranty does not cover incorrect installation, nor flow or pressure outside the limits above. Free service is offered within 100 km of the point of sale, and a repair by a technician not approved by TTI voids the warranty.

Winterizing

In Quebec, the heat pump must be winterized when the pool is closed: water left in the heat exchanger can freeze and damage it, and freeze damage is not covered by the TTI warranty. Here are the steps from the TTI manual.

ShutdownTurn off the heat pump, switch off the breaker and close the valves.
DrainingUnscrew the water inlet and outlet fittings, rinse the heat exchanger (called the condenser in the manual) with tap water, then drain it with compressed air or by vacuum. A wet/dry vacuum can remove any remaining water.
ProtectionIf the unit stays outside all winter, cover it with a waterproof protective cover.
MaintenanceKeep the coil free of leaves and paper. Clean it with a mild cleaner and rinse it with a hose at low pressure, never with a solvent or gasoline.
RestartCheck and adjust the water quality, make sure the breaker is off, install the unit level and connect the plumbing, clean the filter and check the water return, then switch the breaker back on. Start the filtration pump before the heat pump.

Frequently asked questions

What size pool can the Stratos-80 heat?Proper sizing depends on the water volume, wind exposure, the use of a cover and the target temperature. The Stratos-80 is the largest Stratos model offered by AFI: send us your pool's shape, dimensions and depth, and we'll tell you whether it is suitable or whether a smaller model is enough. For a very large pool, TTI provides for connecting two units in parallel.
Is it compatible with a saltwater pool?Yes, its heat exchanger is made of titanium. However, TTI requires that the outlet of the salt chlorine generator, or of any chlorine or bromine feeder, be placed after the heat pump; otherwise, the warranty is void. Keep your water well balanced.
Does it work with a variable-speed pump?Yes. According to TTI, the Stratos is designed to run at reduced flow with modern circulation pumps. The condition: keep at least 57 L/min (15 US gal/min) flowing through the heat pump while it is heating, without exceeding 170 L/min (45 US gal/min). Outside this range, damage is not covered by the warranty. Set your pump speed accordingly during heating hours.
How much does it cost to run?It depends on the air temperature, the target water temperature, the number of heating hours and the pool's heat losses: a reliable figure requires knowing your setup. Two pointers help lower the bill. According to TTI's spec sheets, the COP (the heat produced for each unit of electricity consumed) is markedly higher with air at 26.7 °C than at 10 °C (water at 26.7 °C and 63% humidity in both cases): heating during the warmest hours of the day therefore costs less. And TTI recommends an insulating cover or a solar cover to keep the heat in at night.
How late in the season can it be used?According to the TTI manual, the Stratos is designed to operate with an air temperature of 7 to 35 °C (45 to 95 °F), and a protection feature shuts it off automatically when it gets too cold. In Quebec, it is therefore used to warm the water as soon as the pool opens in spring and to extend the swimming season as long as the air stays within this range. It must then be winterized before freezing weather.
Stratos-65 or Stratos-80: which one should I choose?The Stratos-65 has a nominal capacity of 65,000 BTU/h, and the Stratos-80 a nominal capacity of 80,000 BTU/h. They share the same water flow range (57 to 170 L/min), the same 1½ in. connections and a 240 V power supply; the breaker rating is shown on the nameplate of each model. The Stratos-80 is mainly justified for a large pool, a poorly sheltered pool or one without a cover, or if you want the temperature to rise faster. For a medium-sized, well-covered pool, the Stratos-65, or even the Stratos-50, may be enough: we'll compare them with you.
How does the warranty work?According to TTI, a new heat pump purchased on or after October 5, 2026 is covered for 6 years parts and labour in Quebec, from the delivery date. TTI asks you to register the unit online. For a claim, you need the serial number, the proof of purchase and the retailer's name: call us and we'll guide you. The terms of the TTI limited warranty notably exclude damage caused by freezing, by flow or pressure outside the limits and by incorrect installation.
