Air and ground source heat pumps utilize energy in the air and in the earth surrounding a property to provide a heating and cooling solutions. Highly efficient compared to traditional energy sources, heat pumps can help achieve massive savings.

Danfoss heat pumps can be used for heating or cooling down your home. They provide primary heating and deliver domestic hot water. Our technology ensures optimum indoor comfort, no matter what the temperature is outside; -25 or +35 Celsius. Besides that, it also contributes to increased annual efficiency, comfort and reliability. Danfoss heat pumps can be integrated with various complementary heat sources such as solar or gas systems.

How does a heat pump work

Heat pump is able to produce more energy than it consumes by using the conventional refrigeration cycle to absorb heat from the environment and raise it to a suitable level for heating.

Danfoss OnLine - control the heat pump remotely

With the Danfoss OnLine accessory you can control and monitor your heat pump from any mobile phone, computer or tablet, wherever you are in the world.

For example, you can lower the temperature in your home whilst you are on holiday, and increase it again for when you come back. If you come home earlier than expected; no problem – using OnLine, you can easily ensure that your house is warm and comfortable whenever you need it to be.

At any time of day, you can use OnLine to check that your heating system is working and what temperature your home is at. If anything unexpected comes up and needs to be fixed, you – or your installation engineer, where agreed – will immediately receive this information via OnLine. You can also control and monitor several locations if you need to; for example, if you have a summer cottage with a heat pump or have relatives who need assistance. OnLine is, of course, available for both Android and iPhone.

New OnLine can be connected directly to your existing broadband at no additional cost

With New OnLine customer/installer is always updated that heat pump works properly, can check the status of the heat pump and change settings (mode, temperature, calendar) via the smartphone application or PC – wherever, at anytime 

Alert function for maximum safety: Heat Pump alert function via apps or e-mail sent to customer and/or installer 

Quick and easy installation: Simply connect the DCM Device to your internet using an Ethernet cable from the heat pump to the homes router for minimal hassle and maximum results 

New OnLine works with all our current domestic heat pumps and can be offered to new and old customers regardless of what type of heat pump they have

Are there any differences in the annual performance of an air source heat pump with a frequency controlled compressor and a standard compressor?

No, there is no scientific proof of positive seasonal performance improvements from frequency controlled compressors

Is R407C an old-fashioned refrigerant?

No, R407C is considered to be the best refrigerant by the heat pump sector for delivering optimum seasonal performance

Is R407C bad for the environment compared to R410A?

No, the global warming potential (GWP) of R407C is 1,610 and for R410A 1,890, making R407C less damaging for the environment

What is seasonal performance?

Seasonal performance express the performance of a heat pump over a full year given the heating distribution system, hot water system and the actual customer demand. Proper dimensioning, installation and commissioning is needed to obtain highest possible seasonal performance. Seasonal performance is the standard measure for Danfoss heat pumps when designing and building heat pumps, as seasonal performance is the real measure of efficiency.

The Swedish Energy Agency has conducted a large test of air/water heat pumps. Of the eleven heat pump models in the test, DHP-AQ from Danfoss yields the biggest savings. It also has top results when it comes to hot water temperature, low noise levels and low energy losses.

Is performance at rating points (COP) a proper denominator for seasonal performance?

No, performance at rating points merely expresses the efficiency in a number of points typically measured in a laboratory, and has no direct relation to the seasonal performance of a heat pump

Are systems build on direct expansion (DX) more efficient than indirect BW systems?

In theory yes, but in practice no. DX systems needs to be refrigerant-charged on site, hence no possibility to do factory tests or factory performance optimisation. Similarly the copper collector can easily be damaged during installation, which will lead to serious reduction and loss of efficiency

Will the Danfoss heat pump work in combination with single room controls?

Yes, Danfoss control system properly commissioned will work perfectly alright with single room controls

Is it better to over-dimension than under-dimension the heat pump?

No, neither is good, the heat pump must be adequately sized for the specific heating distribution system and the end-user requirements, dimensioning done via the HPC program will ensure that you select the right sized HP

Can you dimension a HP only to the size of the house and occupants?

No merely considering these dimensions will not lead to choosing a right sized heat pump, proper dimensioning need to be done by considering climate data, insulation level or present energy consumption, heating distribution system, hot water and heating demands etc. This needs to be done in advanced programs like the HPC dimensioning software

Energy Efficiency of Heat pumps

The entire range of our domestic Danfoss air and ground source heat pumps comes with the highest possible rating from A+ up to A+++ depending on the model, heat receivers and integrated system.

ErP Ready

The Energy Related Products Directive (ErP) is a piece of European legislation setting minimum efficiency standards for energy using equipment. As of September 26th 2015 this was extended to heat pumps and other heating sources.

A+ to A+++

The rating system for heat pumps classifies them into nine efficiency categories. The best category is A++ and A+++. The labels are applied to heat pumps as single source of heating, and combined with domestic hot water preparation as well as the whole integrated system, including solar thermal power, temperature control, etc.

Domestic Danfoss air and ground source heat pumps come with the highest rating from A+ up to A+++ depending on the model,  receivers and integrated system.

Energy labels

The energy efficiency categories for heating heat pumps are based on a seasonal coefficient of performance (SCOP). This depends firstly on the climatic region and secondly on the potential heating system. Europe is divided for this purpose into three climatic regions. For radiators and underfloor heating systems, the different flow temperatures and possible energy efficiency categories are shown on the Energy Labels.

Did you know?

Stand-alone heat pumps are rated a maximum of A++ and as part of integrated system can be rated as an A+++. Heating boilers (oil, gas, bio-mass) on the other hand are rated A at best, and in some cases as low as C or D. If the end-user is interested in top efficiency that is A+++ energy class rating they should look at heat pump as part of an integrated system.
