Maruyasu Industry Expands Solar Thermal System ReTerra Sales Area to Tokyo for Eco-Friendly Homes

Maruyasu Industry Expands Its Reach with ReTerra in Tokyo

Maruyasu Industry, a prominent manufacturer of automotive components, is thrilled to announce the expansion of its solar thermal water heating system, ReTerra, into Tokyo. This move aligns with the city’s commitment to reducing CO₂ emissions from households, further supported by a generous subsidy program.

Subsidy Program to Encourage Adoption

Tokyo has set up a subsidy program that grants families up to 550,000 yen for the installation of solar thermal systems, effectively lowering the financial barrier for residents looking to invest in environmentally friendly technologies. By leveraging these subsidies, homeowners can significantly reduce their initial installation costs, making it both an eco-conscious decision and a savvy economic one. In certain cases, families may see a return on their investment in under six years, allowing for considerable savings on long-term utility bills.

To ensure a smooth transition for new users, Maruyasu Industry is offering complimentary assistance with the subsidy application process. The company prides itself on providing thorough support to first-time adopters, facilitating an easy implementation experience.

Special Campaign for Tokyo Residents

To celebrate the new sales area, Maruyasu Industry has launched a limited-time campaign specifically for Tokyo residents.

- Application Period: April 21, 2025 to June 30, 2025
- Price: Regular price 730,180 yen (tax included) → Reduced to 442,860 yen (tax included, excluding installation costs)
- Eligibility: Residents of Tokyo

Benefits of ReTerra

The ReTerra system is designed to make a substantial impact on energy consumption and CO₂ emissions. On average, hot water accounts for approximately 30% of a household's energy use. ReTerra enables families to reduce their hot water energy usage by about 40%, offering a dual benefit of environmental sustainability and reduced utility costs. An individual household using ReTerra is estimated to cut down on CO₂ emissions by about 500 kg yearly, translating to significant environmental value. Maruyasu Industry sets its sights on selling 400 units annually, which could lead to a reduction of around 200 tons of CO₂ emissions per year. This is equivalent to the amount absorbed by approximately 14,000 cedar trees within the same timeframe (based on a CO₂ absorption rate of 14 kg per tree).

Emergency Preparedness

Beyond its everyday utility, the ReTerra system also provides critical support during emergencies. In the event of a water supply disruption, ReTerra can store up to 200 liters of warm water, which can be utilized for both drinking and household needs. Given that each person requires a minimum of about 3 liters of drinking water daily, this storage capacity equates to approximately 16 days' worth of water for a family of four.

Supporting Assurances with ReTerra LINK

To enhance user confidence, Maruyasu Industry introduces the ReTerra LINK maintenance and monitoring service, powered by IoT technology. This service automatically detects any abnormalities in the system and promptly informs the customer, ensuring rapid and precise responses to any issues. This innovation eliminates the previous need for regular inspection visits, significantly reducing hassle and anxiety for users, and delivering peace of mind.

Robust Warranty Program

ReTerra stands out in the industry with an extended warranty package, offering a remarkable guarantee of up to 15 years, one of the longest in the market. A standard warranty covers consumables and electrical systems for five years. Customers can extend this to a maximum of 15 years through the optional ReTerra warranty package. This robust warranty reflects the trust built over years of producing critical automotive parts, underscoring Maruyasu Industry’s commitment to quality and customer satisfaction.

Future Development and Market Strategy

Maruyasu Industry is strategically expanding ReTerra's distribution within western Tokyo, where gas supply is comparatively low, and many households rely on more expensive LP gas. The affordability and effectiveness of ReTerra make it an appealing investment in these areas. Tokyo's support for solar thermal systems through its subsidy initiative plays a crucial role in this expansion, enabling families to cover roughly half of their installation costs with financial assistance. By using these subsidies, Maruyasu hopes to significantly lower the barriers for homeowners, making solar technology an attractive option.

As Maruyasu Industry continues to promote the ReTerra system, it remains dedicated to contributing to the reduction of greenhouse gas emissions and fostering a sustainable future, while also exploring new opportunities within the renewable energy sector.
