HYSS - more than a heat pump!

Free Energy’s vision is to provide solar-based energy systems that can deliver all the energy that a building could need. We have therefore developed HYSS - a hybrid heating pump - the most cost-effective and environmentally friendly heating system on the market.

Fact 1
A typical roof in Norway receives annually 4-5 times more solar energy than the household consumes in a year.

Fact 2
In less than 1 hour, the global solar radiation will be equivalent to Earth's annual energy consumption.

Fact 3
If 2 thousandths of Norway's land area were covered with solar collectors (efficiency 50%) and solar panels (efficiency 12.5%), it'll be equivalent to the country's annual energy consumption.

 HYSS - Hybrid Solar System - an innovative combination solution that utilizes solar heat and heat pump technology in an optimal way. HYSS can easily be configured into a geothermal pump, ground heating pump or marine heating pump, all of which can be combined with solar heating. It is also possible to combine an air outlet with a shorter ground loop or a shorter bore hole. No matter what type of heating pump you have, performance will improve with solar heat, which means that you get a very efficient operating system. The solar heat generally halves the operating time of the compressor, which causes the heating pump to have a significantly longer service life. With an HYSS system you get 5-7 parts of heat and hot water for each part of electricity that the system uses.

 

This results in a shorter payback period of the system, because the solar collectors is being used for both hot water production and to increase the efficiency of the heat pump.

With HYSS you will get a complete heating system ensuring both heating and hot water and is suitable both for new buildings and rehabilitation or replacement of existing heating systems.

HYSS is delivered with integrated measuring equipment allowing you to monitor the performance of the system both in real time (COP) and for longer periods of time (SCOP). With internet connection you'll automatically get the latest and best software available. Everything is designed to get the best experience with a modern iPad application leaving you in full control of your system anytime and anywhere.

HYSS - a unique heat pump powered by the sun

Utilization of solar energy for heat pump efficiency is designed as an integrated part of the heat pump. That is why you will achieve very good operational economy without excessive investment costs.

Intelligent management of priorities for the use and storage of low, medium and high temperatures from the solar heat results in a higher annual efficiency (SCOP).

To heat and hot water, 7-8 months

High temperatures from the solar collectors are stored directly in the tank. For 7-8 months a year solar heating alone manages to heat the storage tank above 60ºC without supplementary energy from the heat pump. In this way, the solar heating provides virtually free hot water in large parts of the year which improves the annual efficiency (SCOP) for the HYSS-system. During the summer months the solar heating also contributes in decreasing operating hours of the heat pump.

 

Heat pump efficiency, all year

When the heat pump i operating, the solar heat preheats the brine fluid to increase the efficiency of the heat pump. A specially made inverter controlled compressor makes it possible to apply considerably higher temperatures than normally to the heat pump.

This contributes to a significant increase in heat factor (COP) for the heat pump. Along with free hot water the annual efficiency (SCOP) is being doubled for the HYSS-system compared to a conventional ground source heat pump.

 

Dumping / re-charging, all year

When the collectors has low working temperature or when the storage tank is fully heated, solar heat is being used to recharge the borehole or ground loop. In this way the temperature recovers in the energy storage faster and results in increased efficiency of the heat pump. High temperatures are simultaneously being avoided in the storage tank because the excess heat from the solar collectors may be dumped in the energy storage in the ground in a simple and secure way.

You can increase the performance in an existing borehole or ground loop with HYSS because the solar heat re-charges (dumps) the excess heat all year around. This means that you can utilize existing collector even if you install a more efficient heat pump with higher power output from the collector. Thus, the use of electric heating element is reduced to a minimum. It also applies if you have extended your house and increased your energy and output needs.

You save more money with solar heating and heat pump

HYSS utilize nature's best resources and here we will explain the interaction between solar heating and the heat pump.

Solar heat preheats the brine fluid* when the heat pump is operating to improve the efficiency of the heat pump. Considerably higher temperatures than normal is being used to the heat pump due to our inverter controlled compressor. This will contribute to a substantially higher annual efficiency (SCOP) for HYSS compared to conventional technology.

Free Energy have verified how much preheating of the brine fluid* constitutes:
Testing at Danish Technological Institute shows when brine temperature is increased by 10 degrees the heat efficiency (COP) of the system increases by 36 percent. If the brine temperature is increased by 20 degrees the heat factor increases by 98 percent.

*Brine is a glycol fluid in the closed system of the heat pump and HYSS-system.

Lower operating costs with highest energy rating A+++

Free Energy's inverter controlled heat pumps in the power range from 2 to 12.1 kW in combination with solar collectors has achieved highest energy labeling (A+++), for both heating and hot water according to current eco-design and energy labeling requirements which came into effect on 26 September 2015

Eco-design requirements and energy labeling are common to all EU countries and will facilitate energy labeling of heating products. Market surveillance is now being introduced to ensure that heat pump products meets current legislation within the EU's common market. Market control will protect consumers and ensure fair competition between manufacturers. NVE (The Norwegian Water Resources and Energy Directorate) supervises that eco-design and energy labeling requirements ar met in Norway. Products which doesn't meet the eco-design and energy labeling requirements cannot be traded within the European Economic Area (EEA). NVE may order correction or issue decisions about sales ban if illegal products with incorrect labeling is uncovered.

Free Energy's Hybrid Solar System (HYSS) achieves the highest energy efficiency rating for both heating and hot water in all of its three heat pumps in the villa market. The solar-circuit supplies heat directly to the water heater when the temperature is sufficiently high. The heat from the collectors is also used to raise the temperature of the heat pumps incoming brine for a large part of the year. In some cases heat is returned to borehole or ground loop. By utilizing solar heating where it provides the most benefit, the heat pump's SCOP-combi (heating and hot water) increases to 5-7.

You can monitor the system's instantaneous heat factor (COP) and the efficiency for longer periods (SCOP) through the supplied iPad. Software is automatically updated.

HYSS – get your own zero-energy or plus-energy house

Solar energy enables zero-energy and plus-energy houses for both new buildings and existing buildings being renovated.

Future buildings will meet environmental challenges and there are many good reasons to choose an environmentally friendly housing. Better health (indoor climate), eco (reduced CO2 emissions) and economy (reduced costs of heating and hot water).

In the future will all houses probably be built as passive houses. Depending on how much energy the house consumes, but also produces, will determine whether it is classified as a passive house, zero-energy house or plus-energy house. Passive house means that it is well insulated, but additionally utilizes the heat from humans and technical equipments. A zero-energy house may have solar cells for production of electricity and solar collectors with heat pump for heating and hot tap water. This makes it possible for the house itself to generate the energy needed for household, heating and hot water. Plus-energy houses produces more energy than the household consumes annually by using solar cells and solar collectors  on the roof and (or) facade.
