We are scaling up and creating flexible microgrids

The increasing electrification in the society, having more electric cars and other electric vehicles, demands more efficient solutions for energy consumption overall, to free electricity for those who need it, when they need it.

ES NordFlex+ can be a part of an energy system or a micro grid, interacting with for example district heating, tariffs for electricity and the amount of hot water in storage. This makes it possible to balance your energy system, producing energy when demand is low and the cost of electricity is low an use the stored energy when demand occurs. Doing that you free electricity from the main grid, available for those who need it at that time.

This way ES products contribute to the energy transition and helps building modern and efficient energy systems, which enables lower costs and less CO2-emissions.

ES NordFlex+ is developed to enable bigger systems with bigger power needs. This can be for example big commercial buildings or as decentralized district heating networks, micro grids.

System design


Based on our bigger heat pumps

ES NordFlex+ system is based on our AW 30, 45 and 90 kW EVI units and can consist of up to 16 heat pumps enabling systems of up to 1.4 MW.

Endless possibilities with ES NordFlex+

Our concept is based on standardized storage products and enables systems of up to 1.4 MW with just a single configuration of the control.


Connect multiple buildings such as factories, offices and housings and create a small district heating grid, also called a microgrid.


Store energy

Battery or fuel cell for temporary energy storage.


System equializer

Use the ES NordFlex+ system solution and create a system equalizer to transfer energy between different users and needs.

Complete energy delivery

Produce heating, cooling and DHW (Domestic Hot Water).


Green power

Power heat pumps with locally produced green electricity and generate maximum green power.


Hybrid solution for enegy optimization

Connect any additive heating source, for example any kind of biofuel burner, to enable cost efficient energy optimization.


A part of the energy conversion!

The almost endless possibilities mean that there is always reason to take a closer look at ES NordFlex + – as a natural part of the energy conversion, and as an enabler for us to be able to achieve the global goals for sustainable development.



The European Union has enormous needs for energy renovation – here ES NordFlex+ can play a crucial role. 


Heat pumps contribute to reduced CO2 emissions, regardless of electricity production, regardless of energy source.


CO2 emissions for different sources generating electricity and energy

Scandinavian design for a Nordic climate

ES NordFlex+ is fully developed for a Nordic climate. Discreet color scheme harmonizes with a stylish Scandinavian design. All included system components come from some of the most reputable European manufacturers – Grundfos, Swep, Sika, Carel and Panasonic.

Because the inside is as important as the outside.


100% compatible – 100% hybrid

ES NordFlex+ is compatible with all types of additional heating source such as district heating, electricity, oil, or different types of solid fuel. In this way, opportunities are created for large hybrid systems for energy type optimization based on, for example, fuel prices.


Simple and efficient installation

Together with our partners, we have created a complete system that contains more than heat pumps and control.

The system also consists of simple, but complete, flow images to facilitate the pricing of the system.

We can also offer a digital tool for calculating how much heat pump power is needed and how the system can be configured within the framework of the existing control’s many possibilities to meet the desired needs for heating, domestic hot water and cooling.

With our unique digital tool, the costs of planning and designing the system are reduced.

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 on site from the display on the control cabinet, or from a smartphone or the web.
