Daikin has launched the X Series, a residential heat pump system that combines heating, cooling, and hot water production in a single outdoor unit. This system integrates air-to-air and air-to-water technologies, offering homeowners a flexible and efficient solution for year-round comfort.

A New Approach to Comfort for Modern Irish Homes

The X Series is designed for new-build and fully renovated homes up to 150 square meters. It provides heating, cooling, hot water, and hydraulic heating through a compact system. This approach addresses the evolving needs of Irish households, where changing weather patterns have led to concerns about overheating in highly insulated homes.

Kyrian Opstaele, General Manager of Daikin Ireland, noted that Irish homeowners traditionally focused on heat retention due to the climate. However, recent hot summers have shifted the focus to include cooling solutions. The X Series offers both efficient winter heating and effective summer cooling, eliminating the need for separate systems.

Integrated Technology and Efficiency

The X Series features a single outdoor unit with five connections, combining air-to-air and air-to-water heat pump technology. This integration allows both functions to operate simultaneously, enhancing flexibility and efficiency. For homes with limited outdoor space, the system reduces installation complexity and eliminates the need for multiple units.

The system uses R-32 refrigerant and supports various indoor unit options, including air-to-air units and hydraulic indoor units. It also integrates with the Daikin Onecta App, enabling homeowners to manage their indoor climate and monitor energy consumption remotely.

Designed with Installers and Homeowners in Mind

The X Series simplifies installation for professionals while maintaining flexibility. With only one outdoor unit to install, commission, and maintain, installers benefit from a streamlined process. Homeowners enjoy a cleaner exterior appearance and lower long-term maintenance requirements.

Every installation is supported by Daikin’s Stand By Me platform, providing access to a nationwide service network and full after-sales support. This ensures homeowners and installers have assistance throughout the system’s life.

Key features of the X Series include:
One outdoor unit with five connections
Up to four air-to-air indoor units
One Daikin hydraulic indoor unit
180L or 230L domestic hot water tank options
Up to A+++ air-to-air cooling efficiency
Up to A+++ (35°C) and A+ (55°C) air-to-water heating efficiency
A+ domestic hot water efficiency
