Description

A pool heat pump captures the heat contained in the outdoor air and transfers it to the water through a heat exchanger: it delivers several times more heat than the electricity it consumes. This ratio is called the COP. For the Moov Inverter MI1400, it is 5.7 with air and water at 26.7 °C and 80% humidity, or about 5.7 kWh of heat for 1 kWh of electricity. Like all Moov Inverter models, it is Full-Inverter: its compressor and fan modulate their speed to adjust output to demand. Moov therefore claims 30 to 50% seasonal savings compared with a traditional heat pump.

AFI offers the range in four sizes: MI500, MI650X, MI900 and MI1400. The MI1400 is the most powerful, and its design differs from the other three. Those have a side-mounted fan that blows horizontally; the MI1400 has a top-mounted fan that discharges air upward, in an ABS and metal cabinet. It connects with 2 in. fittings instead of 1½ in., and requires a water flow of 133 to 254 L/min and a 50 A circuit at 208–230 V. It weighs 143 kg.

The “140,000 BTU” in the name is Moov's commercial designation, a maximum capacity advertised in 2023 and not certified. The capacity certified to the AHRI 1160 standard is 135,000 BTU/h under the reference conditions. With air at 10 °C (water at 26.7 °C, 63% humidity), closer to a Quebec spring or fall, it is 61,000 BTU/h. Day to day, the MI1400 is controlled from its keypad display or remotely with the Moov Pool app, in Smart mode (recommended for the first heat-up) or Silence mode.

Installation

Who installs it	A pool professional. The manufacturer specifies that a homeowner is not qualified to install it and that the warranty is voided otherwise.
Electrical	Hardwired connection, no plug: no outlet, no smart plug (scheduling is done in the Moov Pool app). In Quebec, this work falls to a master electrician. Grounding required, 50 A breaker and fuse, 2 × 8 AWG cable plus ground up to 10 m.
Ground fault circuit interrupter (GFCI)	The manufacturer does not require one for operation. If the code requires one, its trip threshold must be 30 mA or less; some GFCIs nuisance-trip with variable-speed equipment. Your electrician determines the required protection.
Location	Outdoors, in a well-ventilated spot, with enough room for servicing. Not under an eave, a deck or a porch: the discharged air recirculates, efficiency drops and the unit may shut down.
Clearances	1 m (39.4 in.) clear above, on the air outlet side, and at least 0.5 m (20 in.) all around (walls, shrubs, equipment).
Mounting	M10 bolts on a solid concrete slab, or on a sturdy rust-proofed stand.
Position in the circuit	After the pump and filter, before the water treatment unit (chlorinator or salt chlorine generator). Water inlet at the bottom, outlet at the top. The manufacturer's diagram shows a three-valve bypass.
Plumbing	Rigid pipe required: the fittings cannot support the weight of flexible hose. No more than 10 m of pipe between the pool and the heat pump. Insulate the lines.
Water flow	133 to 254 L/min (35.1 to 67.1 US gal/min) during heating. The filtration pump must provide it and offer a maximum head of at least 10 m.
Commissioning	Start the pump before the heat pump, and stop the heat pump before the pump. Use Smart mode for the first heat-up.

The Moov warranty begins on the date of purchase, or on the date of installation if installation is delayed (with proof). It applies only to the first installation and requires installation by a professional. It excludes electrical wiring and a heat exchanger cracked by freezing.

Winterizing

As soon as the air drops below 3 °C, the manufacturer asks that you turn off the power and drain the heat exchanger, even though the operating range given in the manual starts at 0 °C. Water that freezes inside the unit can crack the titanium heat exchanger, and this damage is not covered by the warranty. Here is the procedure Moov recommends, once the pool circulation has been stopped:

1. Turn off the power	Switch off the heat pump's breaker (off position).
2. Disconnect the water	Unscrew the water inlet and outlet fittings.
3. Dry the heat exchanger	Vacuum the water out through the bottom line with a shop vacuum, or blow through the top line.
4. Antifreeze (optional)	Using a funnel, pour antifreeze into the top line until it comes out of the bottom one. Plug the bottom line with an expansion plug, finish filling from the top, then plug the top line. AFI tip: use an antifreeze designed for pools, never automotive antifreeze.
5. Cover	Put on a cover, leaving some room for air to circulate.

For maintenance, clean the coil with household detergent or clean water, never with gasoline or thinner.

Frequently asked questions

What size pool is it for?Moov rates it for pools of up to 155,000 L (42,000 US gal). This is a manufacturer maximum: actual results depend on the climate, the use of a solar cover and the target temperature, and the manual recommends having the choice of model confirmed by an expert. If your pool is considerably smaller, an MI900 may be enough: the choice depends on the volume, the type of pool (inground or above-ground) and the use of a cover. Give us this information and we'll make the choice with you.

How does it differ from the MI900?Under the same AHRI conditions (air and water at 26.7 °C, 80% humidity), the MI900 delivers 82,000 BTU/h (COP 6.0) and the MI1400, 135,000 BTU/h (COP 5.7). The MI1400 requires a 50 A breaker instead of 30 A, 2 in. connections instead of 1½ in. and a flow rate of 133 to 254 L/min instead of 125 to 158 L/min. It blows air upward rather than to the side, and it is deeper (820 mm versus 419 mm).

How much does it cost to run?It depends on the weather, the target temperature, the hours of heating and the use of a solar cover, which the manual recommends throughout the heating season. Manufacturer reference points: power input ranges from 0.8 to 6.9 kW depending on the operating speed, with air and water at 26.7 °C. Each kilowatt-hour consumed delivers about 5.7 kWh of heat with air at 26.7 °C and 80% humidity (COP 5.7), or 4.3 kWh with air at 10 °C and 63% humidity (COP 4.3), with the water at 26.7 °C in both cases. Moov claims 30 to 50% seasonal savings compared with a traditional heat pump.

Does it work with a saltwater pool?The heat exchanger is titanium, and the manufacturer's diagram places the water treatment unit (salt chlorine generator or chlorinator) after the heat pump. However, Moov does not publish a salinity limit: talk to us about your setup before ordering.

Is it noisy?The manual states a sound level of 50 dB(A) maximum, measured at 3 m (10 ft). A Silence mode is available on the unit and in the Moov Pool app.

Can I heat early in the spring and late in the fall?Yes, within the manufacturer's limits. The manual gives an operating range of 0 to 43 °C for the air, but also asks that you turn off the power and drain the heat exchanger as soon as the air drops below 3 °C. Capacity drops with colder air: 61,000 BTU/h with air at 10 °C, versus 124,000 BTU/h at 26.7 °C (water at 26.7 °C and 63% humidity in both cases). Below 3 °C, it's time to winterize.

Is my variable-speed pump suitable?Yes, if it delivers at least 133 L/min (35.1 US gal/min) during heating hours. At too low a speed, the heat pump goes into protection mode and displays a no-water (E3) or insufficient-flow (E6) code. Program the pump accordingly, and always start it before the heat pump.
