Energy Save – est 2009

The Energy Save company was founded in 2009 and has since then delivered over 20 000 heat pumps for the domestic market. Since 2013 we have delivered over 200 heat pumps for commercial buildings and in 2014 this was made an own product called ES NordFlex.

Energy Savehas also developed innovative and front line plug-in-modules, designed for commercial buildings. These plug-in-modules creates a new market for temporary heat pump installations, a concept that does not exist today. Our plug in modules rationalizes the traditional installation, which often is complicated, time consuming and cost driving, and facilitates the installation with intermediaries men and less coordination.

Though the fully industrialized serial manufacturing we secure quality at the same time as cost can be lowered. The level of freedom for the builder and property owner enables big savings, new opportunities and increased property value.

Energy Save has established an effective and dynamic platform for development and manufacturing together with heat pump manufacturer Amitime in China. The joint developing results has through a wider European and global perspective been very competitive and commercial successful which has contributed to a strengthen both the cooperation between the two companies as well as our market position.

Energy Save develops and offers energy saving products. We offer the market cost-effective, smart and flexible products for maximum energy savings.

Product and concept development as well as system evaluation are done in Sweden and Norway under full control of the Energy Save companies. Production and final assembly of products takes place with ongoing production and quality control of ES personnel, which enables generous product guarantees.

ES heat pumps are tested by independent third parties
To achieve our goal of creating a strong brand with products that meet the high Scandinavian requirements for functionality and power even at low outdoor temperatures, performance testing is a very important tool.

Our facilities are therefore fully tested by Intertek Semko (independent testing institute) according to the standard EN 145 11. It is these test values ​​that we also specify in marketing and all product information. The test method enables comparisons of our plants with other makes where we continuously strive to deliver more power and savings than competitors at an attractive price. Ongoing testing and complete RoHS certificates and reports are conducted and exhibited by Den Norske Veritas (DNV). Ongoing testing and complete CE certificates and reports (LVD, EMC) are conducted and exhibited by Intertek Semko (ITS).
