Remove gases from the water and all equipment in heating systems is one of the basic prerequisites for proper operation.

Total cost of heating energy typically consists of two items. The former is the payment for consumed energy while the latter is the payment for reserved power capacity or reserved energy capacity in given period. If the customer pays for the reserved power capacity, he/she should address two questions: what is the most suitable level of reserved capacity and how to control the heating system so that the reserved capacity limits are not exceeded. Both questions can be readily solved with the aid of model based predictive controller.

The article deals with the determination of emission factors of pollutants from household heating with solid fuels. It also gives the value of specific emissions of PM, CO and TOC and emission balance of household heating in 2001, 2015 and three possible scenarios for the year 2021.

Paper describes selected effects of implementation of biomass microCHP generation in Czech legal conditions. Selected demonstration of biomass CHP is described and basic operational energy balances are presented. Comparison of microCHP and ordinary biomass boiler energy balance were performed. MicroCHP technology WAVE, which is being developed at CTU UCEEB in Buštěhrad, is described. Operational parameters of WAVE and future development outline were discussed.

As a legal expert I often deal with inadequate heating system function. What is common to these devices? Missing balancing valves. It is not possible to assess the flow in connected terminal units that would ensure the necessary transmission capacity from the heat source to the terminal units.

In the previous article we have focused on electricity consumption in the years 2010 to 2016. In this article we try to compare the operational costs with our neighbour's flat of similar size, heated by different source.

In the previous article we described our decision-making process. At the end of this process we decided to install electric radiant ceiling heating panels. In this article you can read how we have realized it.

The article deals in detail with the solar water heater from the EU Commission Regulation 812/2013. It describes what information provides the label and how it originated classification in the relevant energy efficiency class water heating.

The paper presents an example of solving the propagation of noise from an air/water heat pump installed in the basement of an apartment building. Air intake and exhaust are brought out on the façade of the building, where it is calculated the noise situation in the protected exterior of the building. In the interior it is solved the propagation of sound from the plant room to the protected interior space. In conclusion, the results are compared with the data from the report on measurement at the realized work.

For more than a year, a nearly zero-energy standard has applied to certain buildings. In the Czech environment, specific technical parameters for such buildings have been known for three years. And for over six years, the Directive on energy performance of buildings has been in force, imposing the obligation upon EU member states to introduce this standard.

Nevertheless, it seems that for many experts, including those in the field of energy, this term is still quite unclear. Many imagine buildings coated with photovoltaic modules from the ground to the roof, buildings which are better than passive ones or buildings which are self-sufficient, i.e. completely independent of public energy networks. Given the fact that the concept of a nearly zero energy building is very distant from such notions, and because this standard will soon become obligatory for all buildings, including small family houses, let's have a look at what a nearly zero-energy building really is.

The paper gives a simple method for calculating the annual production of condensate in the condensing boiler.

The article describes the impact of the contemporary and future legislative requirements for new buildings in terms of their conception and utilization of renewable resources. Soon, the requirement of quality standard is going to be effective in the Czech Republic that is called building with nearly zero energy consumption. That quality standard is defined at national level by legal regulations based on the requirement of European standard. On examples of family house, residential house and administration building, the impact of the to-be-established requirements for building conception is being demonstrated from the construction as well as the technical systems' point of view. With the existing development trend maintained it can be expected that a building with nearly zero energy consumption will have, comparing to an existing building, a better quality building shell, technical systems working with high efficiency and potentially may but needn't be, partially supplied by renewable energy resources.

This article summarizes the basic concepts of Commission Regulation EU 811/2013 and 812/2013, focusing on solar equipment, solar water heaters and solar packages. Describes the responsibilities of suppliers who place such products on the market.
