Oterra 115V is a new single-zone system that uses Daikin inverter technology
Daikin said that the inverter compressor is the “heart of a Daikin system”
Oterra 115V uses difluoromethane (R32) as the refrigerant and has a heating capacity of 9,000 BTU/h to 12,000 BTU/h
Daikin, a Japanese manufacturer, has launched a new heat pump series for residential use that allows homeowners to heat and cool spaces independently.
Oterra 115V is a new single-zone system that uses Daikin inverter technology and the company’s new Signa flareless adapter for simpler installation and copper pipe connections.
In a statement, Daikin said that the inverter compressor maximises energy savings, providing “absolute comfort”, while only providing energy needed to heat or cool an area.

Oterra 115V uses difluoromethane (R32) as the refrigerant and has a heating capacity of 9,000 BTU/h to 12,000 BTU/h. The range spans heat levels of -15C to 18C, while the cooling range is between 10C and 46C.
It also features a cooling seasonal energy efficiency rating of up to 20 and a heating seasonal performance factor of up to nine. Sound levels are recorded at 25dB for indoor units and 46dB for outdoor units. The new range relies on a single-slot 15A breaker and comes with a 12-year parts limited warranty.
The technology is ideal for applications that may be unable to accommodate a 208/230V circuit, Oterra 115V single-zone systems are designed for ease of both installation and maintenance, while providing strong efficiencies, the company said.
Maintenance is simple, according to the company, with easily detachable drain pans, cooling coils with anti-corrosion treatment for outstanding cleanliness and lifespan, as well as an automatic defrost cycle. The Daikin ONE home app is compatible with it, too, for delivering error and service notifications.

He has written about sustainability issues across numerous industries, including maritime, supply chain, finance, mining, and retail. He has also written extensively for consumer titles like City AM, The Morning Star, and The Daily Express.
In 2020, he covered in detail the International Maritime Organisation’s (IMO) legislation on sulphur emissions and its effects on the global container shipping market as online editor of Port Technology International.
He also explored the initiatives major container ports and terminals have launched in order to ship vital goods across the world without polluting the environment.
Since then, he has reported heavily on the impact made by environmental, social, and governance (ESG) practices on the supply chain of minerals, with a particular focus on rare earth mining in Africa.
As part of this, in 2022 Max visited mines and ports in Angola to hone in on the challenges being faced by one of the world’s biggest producers of rare earth minerals.
His most recent sustainability-related work came much closer to home, as he investigated the eco-challenges faced by independent retailers in the UK, specifically looking at how they can cut emissions and continue to thrive.
