The use of modern technologies based on renewable energy sources distinguishes our investment from all other investments of this kind in Poland. The source of the central heating of the building is a heat pump that uses the heat of the earth by means of 10 100-metre deep bore-holes. Additionally an installation of 10 solar collectors placed on the roof of the building will support heating of domestic hot water. There will be underfloor heating in every apartment - perfect to cooperate with ground-source heat pump, esthetic, comfortable and energy-efficient. Innovative solutions planned for this facility are a huge advantage in terms of ecology and finances for the future residents of the building as they mean lower bills for heating and water. |
4 most important advantages of a heat pump:
ECONOMYCompared to heating systems based on other energy carriers a heat pump is the cheapest way of heating a residential building. Installation of a heat pump brings increased capital expenditures – the difference in these expenditures as compared to other heating systems is amortized over the period of 5 – 10 years. Comparison of heating costs based on market prices of fuel in June 2013 are presented in the table below: Comparison of running costs of heating with different energy carriers (Gross cost was obtained from 1GJ of heat energy according to market prices in June 2013)

ECOLOGYCompared to a heat pump powered by electricity other heat sources based on fuels emit exhaust gases: mainly nitrogen and sulphur oxides and CO2 and such release is of a diffuse nature which it is practically impossible to reduce in an economically reasonable manner. This has a considerable impact on the climate from micro scale (e.g. small towns threatened with smog) to large scale phenomena associated with global warming. Concentrating fuel combustion in power plants facilitates undertaking pro-environmental measures such as flue gas desulfurization technology and in the future – perhaps even – the CO2 sequestration technologies. The energy extracted from the ground by heat pumps is renewable energy. A heat pump using the so-called “shallow geothermal energy” resources (up to the depth of approximately 100 m) almost entirely uses solar energy deposited in the ground every year as a result of sun exposure and by rainwaters. With the COP of 4 the energy passed on to a building comes from the ground in 75 %. The essence of the operation of a heat pump is extracting heat from one source and transferring it to another. This is of great importance when there is a need for air-conditioning of the premises and equipping the building with energy-intensive air conditioners. In a building equipped with a heat pump the need for air-conditioning may be solved by proper energy management: using part of the heat (the so-called waste heat ) to warm up domestic hot water and the accumulation of the excess energy in the ground. |

COMFORTManagement of heat energy in a building equipped with a heat pump is fully automated. The heat pump along with associated equipment is non-stop set to a standby mode – the system is turned on in response to temperature changes that affect thermal comfort of the building. |

DURABILITYA heat pump and associated equipment are much more durable than fuel boiler room equipment. The only component of the heat pump that is subject to wear and tear is the compressor whose durability according to the manufacturer’s documentation exceeds the period of 20 years. The maximum cost of reconditioning of a heat pump connected with replacement of the compressor does not exceed 10 % of the construction of a district heating substation. |
