Description

Replacing solid fuel boilers with modern heat pumps represents a significant step towards increasing energy efficiency and reducing environmental impact. Traditional solid fuel boilers, such as those using coal, wood, or pellets, require regular fuel replenishment and produce a substantial amount of CO2 emissions and other harmful pollutants. Transitioning to modern heat pumps, which utilize renewable energy sources (air, water, or ground), not only lowers heating costs but also contributes significantly to environmental protection. Heat pumps are highly efficient, capable of generating several times more heat energy for every kWh of electricity consumed, leading to cost savings and reduced strain on natural resources. Additionally, they provide convenient and maintenance-free operation, reducing the need for regular fuel supply while enhancing living comfort. Switching to heat pumps is therefore an investment not only in financial savings but also in long-term sustainability and environmental preservation.

Economic benefits

The benefit of installing heat pumps lies primarily in the reduction of operating costs and energy consumption. By replacing solid fuel boilers, significant energy savings are achieved as heat pumps use renewable energy sources and are much more efficient. They have a high coefficient of performance (COP), which means that they can produce several times more heat for every kWh of electricity, significantly reducing energy bills. The higher the coefficient, the more efficient the heat pump operates and ensures cost-effective operation. At the same time, CO2 emissions are minimised, which can lead to lower environmental charges and contributes to better compliance with environmental standards. The initial investment in replacing the source may be higher, payback is usually achieved after just a few years due to significant operational savings. All of this leads to long-term cost reductions and increased financial efficiency of the heating system.

Environmental benefits

The environmental value of replacing a solid fuel boiler with a heat pump is highly positive. Heat pumps use renewable energy sources such as air, water or ground, thereby significantly reducing the consumption of fossil fuels such as coal, wood or pellets. This transition leads to a substantial reduction in greenhouse gas emissions, especially CO2, which are the main contributors to climate change. In addition, heat pumps do not produce any local emissions of pollutants such as dust particles, nitrogen oxides or sulphur, which deteriorate air quality. This has a positive impact on human health and on air cleanliness in places where traditional boilers are used. Reducing the consumption of solid fuel also contributes to reducing the extraction of non-renewable resources and to the protection of forests. Replacing a boiler with a heat pump also reduces pollution associated with fuel transport and waste handling (e.g. ash).

Examples of implementation of the solution in practice

Replacement of two solid fuel boilers with modern heat pumps The project involved the replacement of two solid fuel boilers with modern Vaillant Arotherm plus VWL heat pumps, which resulted in a significant improvement in the efficiency of the heating system. The installed technology consists of a cascade of three Vaillant Arotherm plus VWL 125/6 high-temperature heat pumps, which are capable of providing sufficient heat output even in colder climates. The heat pumps are connected to a 2,000-litre domestic hot water (DHW) cylinder, which enables efficient hot water supply to the building and increases overall energy savings. The heating system is divided into four separate circuits, which are connected to radiators. This system allows flexible temperature control and optimisation of energy consumption in different parts of the building. https://www.geotherm.sk/nahradenie-kotlov-na-pevne-palivo-za-tepelne-cerpadla/ https://youtu.be/saVM5dxi_Kw?si=VlWPYR0TMWcQSaSS
