NIBE Smart Price Adaption

With Smart Price Adaption, the heat pump receives information about the electricity prices for the next 24 hours and then adapts the operation to these. The function is based on information about the hourly prices of the coming day from the electricity exchange NordPool Spot. The prices in combination with expected heating and hot water needs then automatically control the heat pump. This is in order to reduce energy costs and which in the long run contributes to a smaller environmental impact.

NIBE ERS S40-350

The NIBE ERS S40-350 is a heat recovery ventilation unit with low energy consumption, a level of efficiency up to 85%, a built-in humidity sensor and a reheater. Thanks to the rotating heat exchanger, the moisture in the exhaust air is also recycled. The moisture in the air is recycled. The heat recovery ventilation unit is used in houses up to 250 m2 and can even be placed in cold spaces. NIBE ERS S40-350 is delivered in left-hand version with regard to duct connection, but can also be converted to right-hand version.

NIBE FLM S45

The NIBE FLM S45 is an exhaust air module with built-in fan, specially designed for combining recycling of mechanical exhaust air with a NIBE ground source heat pump, providing an integrated solution for ventilation, hot water and heating. The NIBE FLM S45 has a high fan capacity and low noise level. Energy is recovered from the ventilation air; even when the heat pump is not in operation, energy is stored in the ground or soil collector and exhaust air energy is thus put to maximum use.
