System Description

As one of the first brands that developed technologies aimed at energy saving and environmentally friendly technologies such as the technology using condensation, Geminox quite naturally pays attention to technologies that use renewable energy sources. Currently, the Geminox brand is still actively trying to develop a complete range of solutions connecting high performance, energy saving and environmental awareness. Geminox condensing boilers provide everyday comfort while preserving the environment for future generations.

Geminox condensing boilers:

      • devices with optimum performance and technology that enables significant reduction in energy consumption compared to conventional boilers or the use of natural renewable energy sources;
    • the concept based on durable and recyclable materials such as stainless steel in which Geminox is a real expert. This material is easily sorted and recycled and it supports sustainable development;
    • production process which integrates a maximum considerate approach to the environment, e.g. the painting line in a factory is designed so that the negative impact on the environment is maximally reduced.

The third stage is adaptable equithermal regulation integrated in Siemens LMS boiler control unit which prevents unnecessary exposure of walls of the building to cold and optimizes thermal comfort in the building and increases the efficiency of the entire heating system. The above-standard saving is offered by condensing boilers by connecting solar collectors. LMS control unit is ready for easy extension of the heating system and by other alternative sources.

.

The fourth stage is the intelligent speed control of a low-energy circulating pump of Class A. This feature significantly reduces the return water temperature during transition periods and thereby dramatically expands the zone of the use of condensation. Also the overall reduction in energy consumption is not insignificant.

The fifth, the most important stage is represented by a wide linear modulation allowing uniform heating of the building without unnecessary cycling of the boiler. It is no secret that during ¾ of the heating season 15-50% of rated output of the boiler is dully sufficient. All conventional boilers, at which it is not possible to reduce the power to these values ​​while preserving the guaranteed efficiency, thus become significantly uneconomic for ¾ of the heating season. One of the most powerful advantage of THRs boilers is the ability to work with the maximum efficiency and without cycling even at the most common outdoor temperatures in the range of 5-15 ˚C. This advantage is mostly demonstrated in modern family houses. Today's new buildings usually have a heat loss around 10 kW. According to the above stated, practically-tested principles it is therefore necessary for the normal operation of such a building to reach the starting power of the boiler lower than 3 kW. If this parameter is not satisfied and the boiler is operated outside its operating range, the so-called cycling begins. Standard boilers with the starting power of 6-8 kW undergo such switching off and on up to 40,000 times per year. This number seems very untrustworthy but after a conversion to heating days in a year it means one start of the boiler every 10 minutes. However, we know from our experience that even minute intervals are no exception. The properly selected Geminox THRs condensing boiler will not make more than 4,000 starts per year in a newly constructed building It must be clear even to an amateur what conclusion can be drawn from these data.

Geminox THRS condensing boilers are, by their parameters, among the most economical devices on the market.

  • Minimum performance greatly affects operation economy (reduction in the number of cycles). Maximum performance provides the comfort of heating and hot water production.
  • If we consider a simple heating system (radiators or floor heating), the appropriate solution is the GROUND condensing boiler with a basic regulation.
  • In the case of a combined heating system (radiators + floor heating), the optimal solution is the THRs condensing boiler in the DC design with a basic regulation.
  • For more complicated systems with a second source of heat (e.g. heat-conducting fireplace) or more heating circuits, the suitable solution is the THRs condensing boiler in the C design with an appropriate regulation of Albatros RVS series..
  • For one-family housing, the usual container volumes are from 48 to 75 litres for one bathroom or a shower and 120 litres for two bathrooms.
  • For a duplex housing with one bathroom per apartment, the container volume of at least 150 litres is desirable.
  • In the case of the above-standard container volume, the required minimum container volume is of at least 50% of the bathtub volume.
  • If the hot water is heated in the solar tank, it is necessary to double the minimum container volume.

Rez kotlom Geminox THRs DCKondenzačné kotle THRs DC

Prevedenie THRs DC naviac umožňuje:

  • vykurovanie priameho vykurovacieho okruhu (obvykle radiátory)
  • vykurovanie zmiešavaného vykurovacieho okruhu (obvykle podlahové vykurovanie)
  • príprava teplej vody pre 1–2 kúpeľne s možnosťou cirkulácie
  • solárny systém prípravy teplej vody
  • možnosť ohrevu bazénu

Kondenzačný kotol THRs DC je špeciálne optimalizovaný na použitie v moderných domoch a je k dispozícii v týchto prevedeniach:

  • Kondenzačný kotol THRs DC nástenné prevedenie samostatného kotla pripraveného napr. do zostavy so solárnym zásobníkom
  • Kondenzačný kotol THRs M 75 H DC nástenné prevedenie s integrovaným zásobníkom 75 l
  • Kondenzačný kotol THRs B 120 DC stacionárne prevedenie s integrovaným zásobníkom 120 l
  • Kondenzačný kotol THRs SET DC kombinácia s externým smaltovaným alebo nerezovým zásobníkom TV

Kondenzačný kotol THRs DC je plne vybavený všetkými potrebnými hydraulickými a regulačnými prvkami vrátane kabeláže. Má zhodnú veľkosť so svojím štandardným variantom určeným pre klasické jednookruhové vykurovanie a je teda veľmi kompaktný. Toto riešenie prináša mnoho výhod, napríklad elegantný vzhľad, malé rozmery, urýchlenie montáže, elimináciu prípadných montážnych chýb. Zároveň znemožňuje použitie nevhodných hydraulických prvkov, ako obľúbené zmiešavacie rozdeľovače pre okruh podlahového vykurovania riadené termostatickou hlavicou. Vzhľadom na svoju konštrukciu nie sú tieto rozdeľovače v kombinácii s kvalitnými kondenzačnými kotlami vôbec schopné plniť svoju funkciu.
