The Italian manufacturer has launched a compact range of propane air-to-water heat pumps for heating, cooling and domestic hot water in residential and light commercial applications, with heating power up to 15.5 kW, a seasonal coefficient of performance up to 5.18 and water temperatures up to 80 C.
Italian heat pump manufacturer Rhoss has expanded its residential heat pump portfolio with the launch of the Electa-PI series, a compact line of reversible air-to-water heat pumps that use propane (R290) as a refrigerant.
The new range is designed for heating, cooling and hot water (DHW) production in residential and light commercial applications. “The new range also stands out for its all-black design, which combines design and functionality, and includes 7 models from 4 to 16 kW, ideal for new installations and renovation projects, especially where replacement of traditional heating systems such as boilers is required,” the company said in a statement.
The system is said to deliver up to 15.5 kW of heating capacity and up to 14 kW of cooling capacity, achieving a seasonal space heating efficiency of up to 5.18 seasonal coefficient of performance (SCOP) at 35 C. It is also capable of delivering water temperatures of up to 80 C.
The smallest model in the range measures 1,210mm x 880mm x 450mm and weighs 198kg, while the largest system measures 940mm x 1,615mm x 460mm and weighs 267kg.
All models in the series are equipped with a DC inverter rotary compressor, an electronically commutated (EC) brushless fan motor and an EC circulation pump, supplemented by an integrated air vent and safety valve system, as well as a factory-installed pump module with a 5 liter expansion tank and a water filter. This system architecture is designed to simplify installation while improving seasonal efficiency through the continuous modulation of both compressor and pump operation, according to the manufacturer.
The heat pump also relies on a microprocessor-based control system, which can be controlled via an external touchscreen panel or a smartphone app available for both iOS and Android. The system enables integrated management of heating and domestic hot water production, including control of a three-way valve, solar thermal integration, anti-legionella scheduling, fast hot water heating and multi-zone operation with mixing valve management.
In addition, the new product offers flexible programming options such as weekly and daily schedules, holiday and anti-freeze modes, energy consumption monitoring and power limitation functions, as well as integration of smart grids and photovoltaic systems. For building automation, the system also supports Modbus RTU (RS485) communication.
For larger installations, Electa-PI also supports master-slave operation of up to six units, enabling load balancing between units, improving system redundancy and increasing overall capacity without the need for a single oversized unit. “The system is suitable for replacing high-temperature heat generators,” the company said.
