Mega Q
Hot water is an essential resource used in a variety of everyday activities. In North America, traditional methods of generating hot water have relied on gas, oil, electric, and steam boilers.
Air-to-water heat pump technology offers an all-electric alternative for generating hot water, reducing dependence on fossil fuel systems. Daikin's inverter-driven Daikin Mega-Q system provides an all-electric hot water solution, making it an ideal choice for commercial buildings with large non-potable hot water demand, The heat source component of Mega-Q should be used for heating water for non-potable use only, not for other applications such as but not limited to space heating or cooling.
Decarbonizing Water Heating in Commercial Buildings
Washington, and New York have implemented bans on certain fossil fuel heating systems as part of these initiatives.
Why is it important?
Most buildings are equipped with traditional, inefficient commercial gas boilers powered by fossil fuels. Commercial gas boilers generally demand large spaces with complex plumbing and safety requirements. They can also require frequent maintenance, including daily checks of temperature, pressure, and water levels. Additionally, periodic scheduled changeovers make operating gas boilers a labor-intensive task.
The Strength of Daikin Mega-Q
Leveraging Daikin's innovative inverter and air-to-water heat pump technologies, the Daikin Mega-Q offers an all-electric non-potable hot water generation solution to support the following:
» Switching out fossil-fuel based technologies to all-electric alternatives
» Alignment with electrification and decarbonization objectives
» Design flexibility for versatile installation scenarios

Technology
How it Works
Daikin Mega-Q is an all-electric heat pump hot water generation system which is built upon 3 main components — heat source unit, cascade unit, and tank controller kit — providing the attributes of a central hot water system but with the simplicity of a split system.
This heat pump system offers energy-efficient hot water generation for a wide range of buildings such as multi-family buildings, offices, hotels, schools, and other large commercial applications.
This advanced system is highly energy-efficient, capable of supplying hot water to commercial buildings even in outdoor ambient temperatures as low as -4°F. The dual refrigerant circuit split system design, featuring Daikin's Inverter driven heat pump technology coupled with an inverter driven cascade unit, ensures reliable performance with customizable high-leaving hot water temperatures ranging from 140°F to 194°F with inlet water temperatures from 41°F to 176°F.
+ Not required for operation of the Daikin Mega-Q system. Field supplied if used in applications.
Dual refrigerant circuit of Daikin Mega-Q achieves high-temperature hot water output.
Daikin Mega-Q takes advantage of the excellent low ambient temperature characteristics of R-410A combined with high temperature boiling characteristics of R-134A to generate high-temperature water up to 194°F.
