ECO床暖 is a residential heating/cooling and whole-house air-conditioning system from Japan’s 株式会社オンレイ. Its official domain, ecoyukadan.jp, mainly introduces its “next-generation underfloor heating/cooling and whole-house air-conditioning” solution. This is not an internet SaaS product; it is a fresh-air, heating/cooling, underfloor air-supply, and radiant comfort system for detached homes, with an emphasis on compatibility with ZEH energy-efficient housing.
The system uses a first-floor indoor unit and underfloor ducts to send cooled or heated air into the foundation space, then helps even out indoor temperatures through floor radiation and low-airflow circulation. Key selling points highlighted on the official site include: whole-home heating and cooling, coverage for areas such as the entrance, toilet, and changing room, less direct draft, reduced temperature differences, 24-hour ventilation, pollen filters, optional PM2.5 filters, and an “イオンクラスター” sterilization and deodorization module. The product lineup includes Type E and Type E3, with the latter positioned more toward whole-house air conditioning.
The website does not publish standard equipment package pricing. Quotes are project-based and must be confirmed through installers or local builders. The site claims that installation costs are about 30% lower than general whole-house heating/cooling equipment, and it shows measured electricity costs for a roughly 93.98㎡ wooden home in Sendai, Miyagi Prefecture: an annual monthly average of about 9,907 yen, about 6,200 yen/month in summer, and about 18,600 yen/month in winter. However, the official site also notes that electricity costs vary depending on climate, home performance, and lifestyle, and are not guaranteed.
Its strengths are its highly focused positioning and suitability for well-insulated, airtight homes. Compared with ceiling-outlet whole-house air-conditioning systems, it emphasizes that no dedicated air-conditioning room or complex ceiling ductwork is required, making construction relatively simpler. The official site also provides substantial FAQ content, showroom information, and user case studies. The drawbacks are limited price transparency and strong dependence on installation quality and building performance. Heating/cooling takes about 12 hours to take effect, so it is better suited to continuous operation. It has no humidification function, and its purchase, installation, and after-sales value are limited for users outside Japan.
It is best suited to homeowners building custom detached homes in Japan who want even temperatures throughout the house, especially households with elderly people, children, or people sensitive to direct air-conditioning drafts. It can also serve as a differentiated residential equipment solution for local builders.
The website is in Japanese and is generally accessible directly from mainland China. Since its business operations, installation network, and after-sales support are concentrated in Japan, Chinese users will mainly find it useful for researching residential equipment solutions rather than for direct purchase and deployment.
