NIBE S735C-7 Exhaust Air Heat Pump
Description
NIBE S735C is an intelligent inverter-controlled exhaust air heat pump with integrated hot water heater that delivers heating, cooling, hot water and ventilation in an energy-efficient and economical way. The built-in cooling function provides a comfortable indoor climate even on hot summer days. The system automatically adapts operation to the property's current power needs and uses the natural refrigerant R290 for minimal environmental impact.
NOTE! Velltra assures that all NIBE products marketed and sold by us are manufactured in Sweden and contain components of the highest quality, specially adapted for the Nordic market and its challenging climate.
Energy-efficient operation and sustainable heating
With a high seasonal coefficient of performance (SCOP), the NIBE S735C provides exceptionally low operating costs all year round. The inverter-controlled compressor continuously modulates the output, which reduces energy consumption and extends the life of the equipment. The solution is designed for both new construction and modernization when replacing older heat pumps. Together with a supply air module, the unit also works excellently in properties with mechanical exhaust and supply air ventilation.
Integrated cooling and quiet performance
The built-in cooling function enables coolness during the warmer months of the year without the need for separate air conditioning systems. The well-thought-out design also ensures a very low noise level and a discreet profile that blends well in the home's laundry room or utility room.
Connected comfort and smart control
The NIBE S series is equipped with integrated Wi-Fi, support for wireless accessories and an intuitive colour touchscreen. The weather-controlled automation analyses the conditions and continuously optimises the indoor climate. Via smartphone or tablet, you maintain full overview and flexible control over your home's energy use, no matter where you are.
Adapted corrosion protection for local water conditions
To ensure a long service life and adapt the unit to local water characteristics, the NIBE S735C-7 is delivered with three different types of corrosion protection for the integrated 178 litre water heater:
- Model CU (Copper): Optimal protection for municipal water and most normal to slightly aggressive water types.
- Model R (Stainless steel): Highly resistant choice for water containing lime or higher chloride levels.
- Model E (Enamel): Equipped with a sacrificial anode, developed for specific water qualities and your own drilled wells.
