- 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.
