Commercial heat pump solutions Unitherm partners with Bluebox
Unitherm Heating Systems’ Commercial Division, with its internal and external support teams, operates as a specialist heat pump supplier that aims to identify and implement the best heat pump solutions for both new-build and retrofit. It is now a market leader in the sector and partners with some of the world’s leading suppliers to bring cutting-edge technology to the marketplace.

A key example is the Bluebox range of commercial heat pumps that offer a diverse range of energy efficient heating and DHW solutions to meet the growing demand for renewable and sustainable systems from the commercial sector. Bluebox was established in 1986 as a specialist in cooling but later became a leading manufacturer of commercial heat pumps, which have been patented. Today it is part of Swegon AB, the Swedish multinational group.
With increased legislation on energy efficiency, there is a growing need to find alternatives to high-carbon oil and gas boiler systems. The Bluebox range of heat pumps meets these challenges. Examples from the range include the award-winning Titan Sky propane low GWP heat pump range, from 30kW up to 200 kW with options to cascade units for greater heating demands. Then there is the newly-introduced Geyser Sky range of high-temperature heat pumps with water temperatures up to 78°C. These offer an ideal solution to DHW production and are an easy boiler replacement.
To meet the heating and DHW requirement, design engineers must understand the legislation and compliance related to heat pumps. Commission Regulation (EC) No 813/2013 established Ecodesign requirements for placing on the market and/or putting into service space heaters and combination heaters with a rated heat output 400kW. This regulation classifies heat pumps into low temperature or medium temperature applications.
Low temperature means an application where the heat pump space heater delivers its declared capacity for heating at an indoor heat exchange outlet temperature of 35°C. Medium temperature means an application where the heat pump space heater delivers its declared capacity for heating at an indoor heat exchange outlet temperature of 55°C. Ecodesign requirements define the minimum values for the seasonal space heating efficiency of both medium and low temperature heat pumps.
EN14825 specifies the rated conditions for both low and medium applications. Regulation 813/2013 legislates that all suppliers and dealers of heat pumps with a rated capacity 400kW must provide a fiche document for their products. The specific technical information required in the product fiche includes the rated heat output, along with the seasonal space heating efficiency calculation per European standards EN14825 and EN 14511 for either low temperature or medium temperature applications.
The Unitherm commercial design team is on hand to provide compliance advice and to help select the right heat pump technology, whatever the project, from the low temperature Zeta HP range to the Zeta HP XT range of high temperature heat pumps.
