Scandinavian design.
For Nordic climate.

ES NordFlex is completely developed for a Nordic climate. The details in stainless steel and the discrete color is in harmony with a stylish Scandinavian design. The system is including heat pumps (Air/Water), multifunctional tanks and a control module. The components are manufactured by some of the well-known European producers – Grundfos, Swep, Sika, Carel and Panasonic. Because the inside is as important as the outside.

A heat pump with nano-coated evaporator

he outdoor unit has one of the most advanced and reliable variable speed compressor available on the market. Whether 1-phase or 3-phase, you will always get an efficient and quality inverter controlled compressor. The outdoor unit contains the compressor and all other components to ensure a reliable operation down to as cold as -25 degree Celsius. The system is de­frosted by a nano-coated evaporator, which works on-demand and has a self-learning control. The high temperate gas is led from the outdoor unit to the heat exchanger in the indoor unit. One huge advantage with this split-system is that no water is led outdoors, which means no risk for freezing.

Indoor unit – stylish and easy to place

Through a high efficient circulation pump and plate heat exchanger optimum heat exchange, from the high temperate gas to the water in the property’s heating system, is ensured. The indoor unit is compact and easy to place even if the space is limited.

Maximum equipped tanks

The multifunctional tanks are equipped with pipes for domestic hot water and solar heating. Having this flexible function, the tanks can be used in a cost efficient heating system, including hot domestic water, property heating and cooling function.

The multifunctional tanks have a PU-insulation, which provides a high degree of isolation. They store the energy from the heating system very efficient, leading to lower consumption cost for heating and hot domestic water.

100% compatible

ES Nordflex is compatible with all types of additional heating source such as district heating, electricity, oil, or different types of solid fuel. It supports additive for district heating without raising the return temperature. The additional heating source is only used to meet spikes in power usage.

Prepared project planning documents

Together with our partners we have developed a complete system which contains more than just heat pumps and controlling. The system also offers simple, but complete flowcharts and tools for calculating the heat pump effect needed, and also tools for configuration possibilities for heating, hot domestic water and cooling.
