Assessment of investment in heating house
Molčan, Filip ; Špiláček, Michal (referee) ; Baláš, Marek (advisor)
In this thesis are presented available solutions for reducing energy losses and the cost of heating a detached house. Theoretical calculations according to EN 12831 covered heat loss and consequently proposed a number of possible solutions to save costs of heating a detached house and their economical evaluation and return on investment.

Solid Fuel Boilers
Skočík, Lukáš ; Špiláček, Michal (referee) ; Baláš, Marek (advisor)
This thesis is engaged in heating of the family house by solid fuel boilers, both fossil fuels and the modern forms of biomass. The first section describes and explains the properties, composition and important characteristic quantities of these fuels. It also discusses the classification, description and processing options of solid fossil fuels and biomass.Then they are briefly described the principles of combustion boilers for these fuels along with their properties, advantages and disadvantages. The last section focuses on the selection of a suitable boiler fuel for the selected reference house.

Solar Energy Applications in Houses
Jankůj, Tomáš ; Špiláček, Michal (referee) ; Poláčik, Ján (advisor)
This thesis is focused on photovoltaics and photothermics. Their source is solar radiation that belongs to the category of renewable sources. At present, great emphasis is placed on ecology and economics. For this reason, renewable sources are coming to the foreground. In the first part of the bachelor thesis, types of photovoltaic cells, technology and their efficiency are presented. Furthermore, the principle and construction of photovoltaic and photothermal systems are described. The second part describes the design of the energy solution of a family house using solar energy.

Methods for determining the properties
Lainka, Pavel ; Špiláček, Michal (referee) ; Hrnčířová, Michaela (advisor)
In this work are elaborated methods for determining the properties of the biomass, which is nowadays a few. Procedures for determining the properties are described by individual standards. Each property has its own standard which accurately describes the procedure for the determination of this property. The introduction describes the general concept of biomass, formation of biomass and its distribution. In the next part of the thesis describes the different properties of biomass. Among the most important features include biomass moisture content, calorific value and ash content, which is determined by gross analysis. These properties are in the conclusion experimentally measured, as described in the standards for some types of biomass.

Comparative study of PV and heat pump in domestic energy supply
Kiša, Michal ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
This thesis focuses on the utilization of a heat pump and photovoltaic system on specific residential house. It clarifies the basic concepts of the heat pumps, photovoltaics and their application on a house. In the description of the house there are mentioned basic parameters, a description of the existing system. There are heat demands calculations for house heating and water heating, calculated according to the theoretical values and these are compared with the actual values. The practical part deals with the design of heat pump and photovoltaic system. Also there are assesses of the purchase prices, the operational costs and the following investment returnability in comparison with a fireplace insert with accumulation storage and an integrated electrical heating element.

Biomass gasification
Kubík, Michal ; Špiláček, Michal (referee) ; Baláš, Marek (advisor)
This bachelor’s thesis deals with biomass gasification technology. The introductory part is dedicated to biomass, its division and basic ways of its processing. The main part deals with gasification itself, describes individual processes of gasification and describes different types of gasifiers in detail. This thesis deals with synthetic gas, its impurities and ways of their removal. In the last section the brief description of selected use of gasification technology in Czech republic and Europe is made.

Analysis of ash from fireplace
Drápela, Jakub ; Špiláček, Michal (referee) ; Hrnčířová, Michaela (advisor)
This bachelor thesis should familiarize readers with the size of analysis of ashes of fireplace inset. The work is posssible to divide into two parts, when the first one is devoted to a description of fireplace insets, fuels and subsequent processes during burning in fireplace insets and to individual methods used for size analysis of particles.The other part is focused on practical measurements of individual samples of ashes and subsequent evaluation.

Heat exchanger design
Vítek, Tomáš ; Lisý, Martin (referee) ; Špiláček, Michal (advisor)
This bachelor thesis deals with the design of an additional flue gas exchanger for the use of residual energy of flue gas. Part of the work is a summary of the knowledge about heat exchangers, their principle, operation and maintenance. The next part of the thesis is the calculation draft of the heat exchanger, calculation of heat transfer and subsequent calculation of hydraulic losses for the designed exchanger. Part of the bachelor thesis is a drawing documentation of the designed exchanger too.
