The quality of dynamic heating lies in accuracy of adjustment of the valves, which depends on the correct operation and efficiency of regulatory processes, and therefore the overall heating efficiency. This article summarizes the factors that affect the accuracy of the adjustment, and presents the results obtained the new working tools.

The author compares use of heat pump with solar systems serving for heating hot water for a block of flats in Prague, in his study. The meteorological data from the station Prague-Karlov and the program developed in the framework of a diploma work are taken for the comparison. The comparison is elaborated both from the energy point of view and economically from an orientation view.

The paper is focused on the problem of measurement of gas flow in closed conduits. It deals with the physical principles of measurement and refers to standardized procedures which deal with this issue. It is also briefly discussed the measurement of temperatures and pressures as these parameters are important for calculations of flow.

This paper is focused on hot water tanks for long-term heat storage. Describes the design of the tanks and and their properties. The evaluation of tanks is based on the results of real systems. Tanks are mainly used for solar systems with long-term heat storage. The use of solar systems with long-term heat storage for building opens new possibilities for further savings of energy from non-renewable sources.

Uncertainty internal heat gains as a result of the behavior of the population can be interpreted in two ways: uncertainty of the total population, which will tend to triangular division and uncertainty of metabolism. The our uncertainty analysis of internal heat gains based on the assumption that a household uses the only electrical energy (P1.14/BA).

We use for measuring of physical quantities devices, in layman's called “meters”. But what to say that the term “meter” is also used for devices that do not measure anything, and even the experts in the given field use this concept. Welcome to the field of billing of heating costs.

Reduce the amount of air emissions, provide households and businesses cheaper to heat and at the same time stimulate the economy and encourage the market for renewable energy sources - these are common goals for the Czech, Austrian, German and British government. Each country, however, these objectives released after different way. While our currently running national subsidies in the UK came this spring with a program RHI (Renewable Heat Incentive) for households. In many ways, this program is unique worldwide and will be interesting to see whether it becomes an inspiration for other European countries, hence the Czech Republic.

Multilayer metal chimneys have some advantages over chimneys with ceramic chimney casing, but their use with solid fuel appliances in wooden houses must strictly follow all the requirements of chimney manufacturer and be in accordance to current norms in order to secure the fire safety of the building. This concerns in particular the passages of chimneys and flues through wooden building structures.

In newly constructed and renovated buildings more often dynamically controllable sources of heat are used. In the recreational buildings dominate cookers and ovens with a combined fan and storage function. It is mainly caused by changes in the energy requirements of buildings, which decreases every year and the market is focused primarily on this type of stoves. But tiled stoves have still a lot to offer - design and use value. Properly designed tiled stoves are suitable also for the low-energy houses and can serve as a primary heat source for heating the house and their efficiency is very high. This article tries to clarify some concepts and principles of proper design of tiled stoves.

This article assesses the subject of modern and efficient ways of using energy from wood that has been widely discussed within the scientific lectures on fair TECHAGRO and BIOMASS 2014. The author outlines the development of the cross-section of the use of wood fuels from forest management in the context of the application of forest logging residues, or sawdust from wood processing industry in the energy sector in the Czech Republic.

Air change rate in a building depends on the weather conditions, building envelope tightness, operation of technical equipment and user activity. On object structural system P1.14/BA were during the heating season (1991–1992) monitored during the opening vent windows (wings). Take into account the impact of opening windows in addition to the minimum intensity of air change rate n = 0,5 + Δn.

Reducing the energy performance of buildings is very important. Equally important, however, is also the correct evaluation of energy savings. In practice, we meet with different approaches to the evaluation of energy efficiency, while some of them are far away from objectivity. This group also includes so called Energy League.

Power industry is one of the greatest producers of waste. The character of waste products from the power industry is quite different from waste arising from the other industrial sectors as concerns its composition, methods of removal and possibilities of use. There has been revealed within the solution of the project “The Resort Research Program in the Force of the Ministry of Environment” ref. no. SP2f3/118/08, bearing the name “the research of real properties of waste considered as an acceptable source of non-standard raw-materials (particularly the secondary by-products from the energy generation) in sense of actual legal requirements for the protection of health, environment and the evaluation of the acquired information for the determination of safety processes and requirements for their use”, that products used for the landscaping, in certain events do not fulfill requirements stipulated for the utilization of waste on the ground surface. It means that construction products made from remainders after the coal burning, being sold as safe, can contaminate the environment more than waste used for the same purpose.

This article focuses on the issue of creation of operating rules that pertain to the field of operational documentation. Operating rules are an essential part of the efficient operation of the property. This article is targeted to the content site of operating rules by various functional use of objects. A method of operation of the building affects the composition of future operating rules. In this article, the individual include the composition and structure defined according to the method of use of the building.

The efficiency of boilers is a major technical and economical parameter and indicates the degree of fuel energy utilization. The aim of this paper is to present basic approaches to determination of the efficiency calculated by direct and indirect method. In the Annex of the article is a list of technical standards (including theirs validity) which deal with determination of efficiency for various types of boilers.

Electric heating systems can be divided according to several criteria. One of them is way of heat transfer. The distribution of thermal energy from one place to another may occur through convection, radiation or conduction. In this article we will focus on the radiant heat transfer.

Concept Data Support Department of the Ministry of Industry and Trade has prepared this statistical report as a comprehensive national statistics on renewable energy sources. The final part of the report provides statistical data of the categories Energy use of waste and alternative fuels, Hydropower, Wind Power, Photovoltaics, Solar thermal systems, Heat pumps and Geothermal energy.

Concept Data Support Department of the Ministry of Industry and Trade has prepared this statistical report as a comprehensive national statistics on renewable energy sources. The second part of the report focuses on energetic use of biomass.
