The Zodiac Z400 iQ pool heat pump series impresses with its combination of elegant design and discreet operation.
The Zodiac Z400 iQ MD4 pool heat pump offers a heating output of 9.83 kW and a COP performance coefficient of 5.89. The
Pool heat pump is suitable for pools with a maximum pool volume of 50 m³.
Advantages of the Z400 iQ MD4 pool heat pump:
Unique design
The Zodiac Z400 iQ heat pump fits elegantly into the surroundings of your pool and impresses with a linear design and two available color variants, aluminum gray and stainless steel.
The version with a stainless steel front panel is particularly corrosion-resistant and therefore ideal for use on coasts.
Absolute discretion
Conventional heat pumps with horizontal fans require a distance of several meters to the front. The Zodiac heat pump Z400 with its vertical air outlet requires a 70% smaller distance.
Thanks to the SILENCE mode and the vertical air outlet, the Zodiac heat pump Z400 is particularly unobtrusive and therefore fits perfectly into all pools, even in confined spaces.
Since the noise pollution is halved in SILENCE mode, the Zodiac Z400 iQ MD4 is practically unnoticeable.
Integrated connectivity
The Zodiac Z400 iQ can be connected to your WiFi and connected to your smartphone via the Aqualink™ app.
This means you can configure and access the various functional modes even over longer distances: water temperature, heating/cooling, standby, SILENCE mode, etc.

Frequently asked questions and answers about the Zodiac Z400 MD4 pool heat pump:
For which pools is the Zodiac Z400 MD4 pool heat pump suitable?
The Zodiac Z400 MD4 pool heat pump is specially designed for medium-sized pools with a volume of 30 to 50 m³. It is an excellent choice if you need a heating system that works efficiently and reliably.
How should the Zodiac Z400 MD4 pool heat pump be set up?
The operation of the Zodiac Z400 pool heat pump requires that it be set up freely within a radius of 0.5m. The minimum distance to the pool should be 2m. Mount the heat pump on the included vibration dampers on a stable, solid and flat surface that can support the weight of the pool heat pump.
How is the Zodiac Z400 MD4 pool heat pump connected?
The Zodiac Z400 is easily connected to the pool's filter circuit thanks to the included half screw connections. To do this, please use a PVC hose ø 50 and place it after the filter and before the water treatment. For optimal inflow, we recommend installing a bypass.
Can I connect the Zodiac Z400 pool heat pump to a normal power connection?
The Zodiac Z400 pool heat pump is designed to operate on a 220 V power line. The rated current is 6.9 A.
What needs to be taken into account when connecting the Zodiac Z400 pool heat pump?
In order to operate the Zodiac Z400 pool heat pump safely, a protection and disconnection device, which is not included in the scope of delivery, is required. The heat pump must also be connected to a ground circuit.
How long does it take for the Zodiac Z400 pool heat pump to heat the water?
Heat pump technology uses the existing thermal energy in the ambient air to heat the swimming pool water to the desired temperature. How long this process takes depends on various factors, such as the current weather conditions, the performance of the heat pump and the temperature difference between the actual temperature of the water and the desired temperature.
The hotter and more humid the air is, the better the Z400 works.
How do I winterize the Zodiac Z400 pool heat pump?
The Zodiac Z400 pool heat pump comes with a winter cover. This cover is designed to protect your Z400 from condensation and is therefore essential to install. To protect the capacitor from frost damage, we recommend switching off the device before winter.
The Z400 has a “winterization” procedure, please follow it.
Well, now it's your turn.
Invest in the feel-good factor with your pool and order the Z400 pool heat pump.
