HEAT PUMPS

We execute heating systems on the basis of heat pumps. We adjust the heat pump on the basis of effectiveness factor of the heat pump calculated dividing heating power of the pump by power absorbed from the power network. The executed heating systems are characterised by effective operation, energy consumption optimisation, and low noise level. We treat every system individually. Heating using heat pump is based on a simple mechanism: it takes heat energy from the lower source which temperature is lower than in the room to be heated. Next, it processes the heat so that it had higher temperature than initially. System based on the heat pump is economical in operation since it delivers more heat than it consumes electric energy. High efficiency factor of the heat pump results from the fact that significant part of heat delivered to the building is taken from the environment. We deal with appropriate selection and distribution of the system depending on the environmental circumstances and the size of the facility. The assembled control system is easy in operation. We adjust the type of the heat pump depending on the lower source of heating in the form of: ground, underground water, or air.

GROUND HEAT PUMP

Execution of the ground heat pump works perfect in wet and clayey soil which have larger efficiency (better density of heat stream) than dry and sandy soil, since the flow of heat stream is three-times smaller which relates to the increased expenditures on pipes. The designed and executed system takes heat from the ground and using the compressor condenses it distributing it in heating devices. It takes heat from shallow strata of the soil (horizontal, pipe heat exchanger) as well as its deep strata (vertical, pipe borehole). Pipes are filled with non-freezing mixture of water and glycol which underground maintains stable temperature from -2°C to +5°C.

AIR-SOURCE HEAT PUMP

We also offer executing a heat pump based on air since it does not require significant interference on the level of construction foundations and may be assembled in a ready building. It is easy to assemble but also it is the most economical option; however, in our climate conditions it requires support in the form of an external hot water boiler. We can assemble the pump outdoors but also indoors. The heat from air is blown into a room through induction units or transferred to the water system.

WATER HEAT PUMP

It is possible to design a water-water heat pump, deliver it and start up. In this case surface waters or underground waters are used which guarantee stable source of heat for the heating system. In case the underground water fulfils the requirements regarding the location and the chemical composition it makes water heat pump an efficient carrier of thermal energy. Two wells are needed for this kind of pump: wet well and sink well. The heat pump takes low-temperature heat from the wet well, compresses it, and distributes it in the heating system. Cooled water goes to a sink well. We also execute pumps based on surface waters by the building from which heat is taken. When executing systems eliminating wells we assemble filters cleaning water from contaminants.

BOILER ROOM

We design and execute boiler rooms on the basis of solid, liquid, gaseous, and electric boilers of efficiency from 50 kW. We offer different ways of carrying off furnace gas: with lower or upper combustion, two-pass, three-pass asymmetrical and reversing. The boiler power is selected on the basis of the heat balance of a building which is included in the building design or calculated from an appropriate formula. We make sure that the boiler has sufficient power, otherwise it will not heat up the surface; on the other hand, the power cannot be too high since it may result in problems of the boiler in achieving appropriate temperature, and overheat. We ensure consultancy in operation, as well as servicing in order to guarantee maximum efficiency and life span of the boiler which translates to minimising the risk to the significant reduction in thermal efficiency and faster burning of fuel.

AIR CURTAINS

We also deal with assembling air curtains: horizontal – above doors and vertical – next to the doors. When used by the entrance it is to create a barrier for the air from the outside in order to mitigate the abrupt change in temperature between the air from the inside and from the outside. Using the air curtain reduces the heating and cooling costs since it prevents the entrance from chilling in winter (warm) or from its heating up in summer (cold). Most commonly used in places with significant flow of people: in hotels, office buildings, pharmacies, supermarkets… etc.

RECUPERATORS

We carry out assemblies of recuperators which are to minimise losses in energy in a building resulting from the necessity of warming up the fresh air from the outside. Recuperator is to remove the used air and supply the fresh air thanks to the two fans installed (exhaust and supply). The used air is transported to the heat exchanger via channel system where it is filtered and exhausted through a discharge channel outside the building. Next, fresh air is sucked in through a supply channel to the inside of the device where the installed filters stop contamination from the outside.  Air going though the heat exchanger is warmed up with heat released by exhausted air. Air supplied to the building takes heat from the exhaust air.

Assembling a recuperator we are sure the air parameters will remain the same and t will be possible to adjust them. The high quality of air without any allergens, pollens, and smells from the outside, but most of all appropriate micro-climate and heating savings constitute additional advantage.

UNDERFLOOR HEATING

We execute different types of underfloor heating which works on the basis of radiation and is allergy sufferer-friendly. Such heating system is efficient and economical since the thermal comfort can be felt at temperature several grades lower than in traditional heating system; however, investment costs are higher.

Floor heating is recommended due to low maintenance costs, eliminating traditional radiators, lack of unfavourable effect of positive air ionization and self-regulation of the system on the basis of changes in temperature in a room. The control systems are selected to automate and optimise influence of different heating zones in the heated rooms. Thanks to using appropriate drivers we may precisely maintain constant temperature in a room minimising significant inertia of the floor heating system and as a result one gets more savings, comfort, and no-overheating.

In wall-mounted heating system heat is transferred to a room on the basis of radiation and requires low temperature of the heating medium (35-55°C). One of the important advantages of the system is the fact that it guarantees best comfort at minimum investment ensuring quick regulation and even distribution of temperature in a room, regardless of the height, eliminating cold areas. Materials used by our company are of the highest quality and guarantee durability confirmed by the manufacturer and allow saving money in terms of operation. Developing the system design allows for better placement and distribution of coil pipes maintaining appropriate distances from the permanent elements of the building ensuring right stream of heat at set temperature. After calculating the heat demand we decide on the type of coil pipes depending on the speed of flow and the hydraulic resistance.

It is also possible to execute overhead heating system which is seen as comfortable and safe. Thermal radiation penetrates a room warming up a floor, walls, furniture, and people inside.
