With the ES NordFlex the property owner gets a good overview and control of the indoor climate.

– So, where would you like to put you energy?

System Design

ES NordFlex offers complex but flexible configurations of heating, hot domestic water and cooling, based on a specific need. Support for necessary mixing valves is standard in the control system. An excellent choice for office property, as well as for residential with demand for combined heating and cooling.

Ready, steady heat – six steps to warmth

By using our standardized methodology ES Systems can provide a cost efficient way for property owners to reduce costs of energy supply. This ensures a safe investment in a highly efficient, open and future proofed energy system offering maximum energy efficiency.



You supply us with information regarding the buildings energy consumption


Energy calculation

A simulation of your property’s energy consumption based on actual climate data from the property´s location is made



If you wish to proceed we help you get in contact with a energy expert who will guide you thru the rest of the process, step by step. The next step is to make a more accurate inspections of your property.

Fixed prize – installed and ready to use

The energy expert present a total quotation containing drawings, project management, products and installation.



The needed drawings is produced by supervision of ES experienced consultants.


Installation, deployment & education

The contract work is performed and when ready the energy expert secure deployment and educate final users, owner or technical staff.


Big savings!

Energy savings from normally 40-50% all the way up to 70% is possible depending on the buildings systems prerequisites.


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

The 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.

With our unique digital tool, The Configurator, costs are drastically decreased in the planning and sizing processes.

The Configurator

Total control – wherever you are

Even when you are not in your property you can manage the heating system – just use the web or your smartphone. The control system is developed by Jeff Electronics AB, who are specialized on user-friendly control systems. Jeff are in a leading position in this market.



A clear and user-friendly interface makes it easy to monitor and control the system from the display on the control cabinet, from a smartphone or from the web. You can control both function and efficiency in real time and customize the system when the demand changes.
