Many systems struggle to balance performance with efficiency.\nZodiac Z400iQ and Z550iQ solve this by combining compact vertical airflow, quiet operation, and smart control. You get stable water temperature with controlled energy use and minimal footprint.\nIdentity\nZodiac Z400iQ and Z550iQ heat pumps, air to water pool heating systems for residential pools, designed for efficient temperature control and extended swimming seasons.", "description": "Designed for these situations\n\nYou replace an older heat pump with high noise and poor efficiency\nYou install equipment in tight technical spaces near the pool\nYou manage a salt pool and need corrosion resistant components\nYou want remote control of temperature and modes from your phone\nYou need stable heating across spring and autumn conditions\nYou compare On Off systems versus inverter technology\n\nExperience the difference in real use\nYou start the season with cold water. In Z400iQ, heating begins with steady output. In Z550iQ, Boost mode increases compressor speed for faster temperature rise.\nOnce target temperature is reached, Z550iQ reduces power automatically. Noise drops and consumption stabilizes. The system adapts instead of switching fully on or off.\nWith vertical airflow, the unit fits closer to walls and structures. This reduces installation constraints by up to 70 percent compared to front discharge units\nMake the right choice\n\n\n\nModel\nPower\nRecommended Pool Volume\nBest Use Case\nTechnology\n\n\nZ400iQ MD4\n10 kW\n35 to 50 m³\nSmall pools, summer use\nOn Off\n\n\nZ400iQ MD5\n12 kW\n45 to 60 m³\nMedium pools, moderate use\nOn Off\n\n\nZ400iQ MD7 TD7\n18 kW\n70 to 90 m³\nLarger pools, extended season\nOn Off\n\n\nZ400iQ MD8 MD9 TD8 TD9\n22 kW\n80 to 110 m³\nLarge pools, high demand\nOn Off\n\n\nZ550iQ MD4\n12 kW\n45 to 60 m³\nMedium pools, stable daily use\nFull Inverter\n\n\nZ550iQ MD5 TD5\n15 kW\n55 to 75 m³\nMedium to large pools, frequent use\nFull Inverter\n\n\nZ550iQ MD8 TD8\n20 kW\n80 to 110 m³\nLarge pools, long season, low noise priority\nFull Inverter\n\n\n\nUse this rule when choosing:\n\nLower range if you use a pool cover and heat only in summer\nMiddle range for regular use from spring to autumn\nUpper range if you want faster heating or have heat loss\nPrefer inverter models for daily use and noise control\nOversize On Off models to avoid long heating cycles\n\nChoose Z550iQ if you want reduced energy use and adaptive control. Choose Z400iQ if you want a simpler system with stable operation.\nWhy this product stands out\n\nVertical air discharge reduces installation space requirements\nIntegrated Wifi with iAquaLink control for remote management\nTitanium heat exchanger resists corrosion in salt and treated water\nReversible operation allows heating and cooling\nMultiple operating modes in Z550iQ optimize performance and noise\n\nMaterials and construction\nBody in galvanized steel or polypropylene.
