RIELLO NEXPRO 300 PLUS HEAT PUMP WATER HEATER 300 LT STORAGE WITHOUT COIL – 20125639

NexPro 300 Plus is the domestic hot water heat pump designed by Riello for residential applications. The unit consists of a heat pump and a boiler.

The heat pump, housed directly in the upper part of the boiler, uses the thermal energy of the air to heat the water in the 300-liter boiler. The air is drawn in by a centrifugal fan that allows for recirculation operation, or through ducting up to 10 meters in diameter (DN 160).

The recovered energy is transferred to the water by an external exchanger arranged circumferentially on the external surface of the boiler, avoiding maintenance costs.

The high efficiency of the NexPro 300 Plus is due to the use of an R134A refrigerant circuit, which uses a high-efficiency compressor, an electronic expansion valve and a hot gas bypass valve to allow the NexPro 300 Plus to operate down to -5°C. The boiler is vitrified (DIN 4753) and is equipped as standard with a 1.5 kW electric heating element.

The heating element performs four main functions: backup heating, antifreeze, emergency heating, and anti-legionella operation. The entire system is monitored and regulated via a control unit that uses intelligent management of the individual components. - DHW production at temperatures up to 60°C - High coefficient of performance - 1.5 kW backup electric heating element as standard - Easily ducted thanks to the centrifugal fan - Double-glazed boiler (DIN 4753) - Solar integration via a Riello Solar-type kit - Anti-corrosion magnesium anode - Operating range -5°C/+32°C.
