What does an electricity bill consist of? Accounting for electricity bills can seem complicated. Apart from the amount that relates solely to the current energy consumption, there are other components on the invoice. The bills are divided into two main sections: Items related to the sale of energy - this is the cost of real consumption The electricity distribution charge -...
Heat Pump Condensate Drainage: What to bear in mind? The amount of condensate generated by a heat pump depends on both the unit itself and the ambient conditions. An hour's operation with a cooling capacity of 1 kW can generate between 0.3 litres and 0.8 litres of condensate. This is a perfectly normal process. However, if the amount of water deviates significantly from these values,...
Why is the bivalent point of a heat pump so important? Heat pumps are a green and very popular solution for heating homes and public buildings, providing energy efficiency and promoting sustainability. One of the key aspects to consider when selecting and designing a heat pump system is the so-called bivalent point. In the following article, we will try to explain,...
Split or multi split - which air conditioner to choose? Deciding to buy an air conditioner is a step towards comfort and better well-being in our homes and workplaces. Choosing the right air conditioning system can be a challenge. The most popular systems on the market are split and multi split units. Each has its own advantages and disadvantages, which are worth considering before...
Low-temperature and high-temperature heating Heat pumps are gaining popularity as environmentally friendly and cost-effective solutions for heating homes and buildings. Although low-temperature and high-temperature heat pumps share the same operating principle, there are important differences in some respects. When deciding to install such a system, it is useful to understand the differences between a low-temperature and a high-temperature heat pump in order to choose the model best suited to...
Photovoltaics on buildings in Poland will be mandatory Mandatory photovoltaics on all buildings? On 12 March 2024, the European Parliament voted on a directive on the energy efficiency of buildings, the so-called Buildings Directive. This means that all new buildings in the EU must be zero-emission. The EU is thus accelerating the energy modernisation of residential and non-residential buildings. Mandatory energy production from the sun The new law...
How much energy storage is enough? Energy storage makes it possible to become independent of the grid supply. Choosing the right energy storage is crucial to the efficient and economical operation of a photovoltaic system. Energy storage allows you to store excess electricity produced by photovoltaic panels so that it can be used during periods of less sunshine or at night. For how long will a domestic...
Energy audit - what is it? An energy audit of a building is the first step towards reducing energy intensity. It is a technical and economic expert opinion on the energy use of the building under study. The result of the audit is not only a detailed report describing the current energy consumption, but also a set of recommendations to help improve the energy efficiency of the building. Such an audit may concern simple modifications as well as ...
Energy voucher for heat pump users From 1 July 2024, the energy shield will cease to apply and instead a maximum electricity rate and an energy voucher will be introduced. The rules regarding the so-called electricity price freeze will change. To protect the poorest households from energy bill increases, the government has proposed the introduction of an energy voucher. The amount of the new benefit is to be ...
Photovoltaic guarantee - how does it work? Purchasing a photovoltaic installation is an investment with long-term benefits. An undeniable advantage of photovoltaic panels is that they have a low failure rate. They are characterised by the absence of moving parts, which minimises the risk of mechanical failure. Nevertheless, warranties for photovoltaic installations are an important element to ensure long-term comfort and safety of use. In the case of photovoltaics, there are...
Dynamic tariffs are a new way of billing for electricity for energy consumers, set to come into force from 24 August this year (2024). Dynamic tariffs are intended to introduce greater flexibility in managing energy costs. They have the potential to reduce electricity bills, but for this to happen, they require consumers to consciously manage their daily consumption....
Photovoltaic mounting systems for flat roofs - what options are available to the developer? Photovoltaic mounting systems for flat roofs are designed to maximise the efficiency of the solar panels while ensuring their stability and safety. Different technologies and methods are used to install panels on flat roofs, which must take into account factors such as the direction, pitch of the panels, load...
