Company profile
01 Overview
Itomic promotes the technical development of the commercial-use CO₂ Heat Pump, which has excellent energy-savings and environmental performance. The heat pump technology is used to boil water with about 1/4 of the electric energy of conventional electric water heaters. This product is available for the Japanese market.

01
ITOMIC CO2 HEAT PUMP from Nihon Itomic Co., Ltd. (Headquarters: Tokyo, Japan; President: Hirofumi Moriya) and its subsidiary Itomic Kankyo System Co., Ltd. (Headquarters: Kyoto Japan; President: Kazuya Kiyotoki) announced that Itomic will launch a new product for the Japanese market, the CHP-15H2 (15kW), on October 1st, 2022.
It’s possible to build a clean hot water supply environment by changing from an existing gas or heavy oil combustion boiler to a CO2 Heat Pump. The Itomic Commercial Heat Pump is a water heater heat pump using natural refrigerant CO2 in consideration of environmental factors and reduced running costs.
02
Furthermore, the CO2 heat pump water heaters that use natural refrigerant (CO2) have a GWP (global warming potential) of 1/2,000 and an ODP (ozone depletion potential) of 0 compared to CFC refrigerant (R410A), protecting the global environment. For this reason, demand is increasing not only in Japan, but also all over the world.
