Biomass Action Plan envisages the available space in 3 variants with respect to the degree of self-sufficiency in food C.R. Area of fast-growing tree species growing steadily, in terms of total energy production is negligible involvement. By registering, according to the law of ash can be removed from the category of waste, and consequently can be applied as fertilizer.

Chimneys with ceramic chimney casing either monolayer (where the chimney casing creates a chimney vent) or multilayer (where the chimney casing is completed with insulating layer and a chimney liner), are a better solution in terms of fire safety of wooden houses.

The object of article is to provide basic information about approaches to testing of stoves burning solid fuels in Europe and some other countries. Generally, stoves in Europe are tested according standard EN 13240. However, there’re other standards on national basis, for example Norwegian standards NS3058 and NS3059. If we look away from European border we can found standards which describe methods of stove testing – Australian/New Zealand standards and EPA standards in U.S.A. The article provides information about measuring sets, characterization of used fuels, testing categories for burning periods, measured parameters, emission limits and others things which are in these standards.

Heat meters are working set gauges and installation can only be performed by a registered company in the Czech Metrological Institute. Yet they are very often used and installed improperly or incorrectly. The following text should be specific instructions on what to avoid during installation of heat meters.

Several regulations gradually tightened thermal characteristics of buildings in France since 1974. The last of them, called RT 2012, based on the requirements determined since 2008 by the national decree „Grenelle de l ‘Environnement“ is important step to nZEB buildings.

The heating period 2012/2013 in Prague based on the observation of Prague-Karlov Station was 234 days, a little longer, and with an average temperature of 5.0 °C, slightly warmer than the long-term average. The basic characteristic of heat demand for heating is 3266 D°(19) degree days, hence, the heat demand is slightly higher than long-term average 3224 D°(19). In the last decade, it is the highest number of degree days for a heating period and the second highest number of degree days than long-term average.

Opinions of the professionals concerned on the issue of fire safety in the operation of chimneys, flues and fuel appliances that address the Government Regulation No. 91/2010, are very different. Since this is a very serious issue, TZB-info wants to provide space for professional discussion, which result should be the unification of opinions.

The market for wood pellets has grown, which is understandable due to the following market growth with boilers and biomass stoves. On the contrary, the market for agro pellets gradually declining. Pellets from agricultural production are completely different type of fuel than wood pellets. These industrial fuel which is in most cases not suitable for domestic heating.

The article is a response to article Proposal for the content of comments to Government Regulation No. 91/2010 Coll. and also warning of the dangers of carbon monoxide poisoning from gas fired appliances.

In accordance with the conclusions of the hearing on 23th July 2012 MV - GD FRS CR we propose to establish clear principles of Government Regulation application to convey its goal of fire safety in the operation of chimneys, flues and heating appliances.

Opinion No 160/2013 of the Czech Association for Technical Equipment of the Government Regulation No. 91/2010 Coll. Conditions of fire safety during the operation of chimneys, flues and gas appliances, issued pursuant to the confusion in the application of the Government Regulation.

The article is a commentary on Czech TV report about the feasibility of reducing CO₂ in the atmosphere. To eliminate carbon dioxide from the atmosphere has been proposed a number of methods, many of which are currently at the stage of mere concept. Namely, this includes the artificial trees mentioned in the report. Even if such methods work, there still remains the question of what to do with the captured CO₂. Storage in geological formations is uncertain and material recovery faces high energy demands. In some cases there is a misunderstanding resulting from the confusion of CO₂ and other emissions. Namely on the facade, which allegedly eliminate CO₂ from the air, but in fact it eliminates nitrogen oxides. The only reliable way to reduce CO₂ emissions permanently is to reduce energy consumption.

Operational guidelines contain instructions for the behavior of workers in a variety of operational and emergency situations, clarify reporting lines and defines the personal responsibility of individual employees. Operating rules contain instructions for the operating individual units and maintenance instructions.

Solar radiation can be utilised in two basic ways. You can either gain heat from solar thermal collectors or electricity in photovoltaic panels. So far, heating of water by photovoltaics was too expensive to compete with conventional solar thermal collectors.
Weight , durability , and currently even the price of solar thermal collectors is comparable with commercially available photovoltaic modules.
Annual energy yield per unit area is approximately twice in the solar thermal collectors compared to the highest quality photovoltaic modules with cells made ​​of monocrystalline silicon, due to the higher efficiency.
In the summer the photovoltaic modules are better when the working fluid is heated to temperatures above 100 °C. In the winter the breaking point is about 40 °C. The advantage of photovoltaics is the absence of heat transfer fluid and easier transfer of energy produced to the point of use. Electricity can also be used more versatile than heat.
If the investment cost of a complete solution of heating water by electricity from photovoltaic panels, either directly or using a heat pump, is lower than the investment cost of the solar thermal system, the PV water heating can be considered as effective utilization of electricity from photovoltaic plants. Such a solution could then be included as an alternative to any grant support for solar water heating.

Extensive modification of TPG 704 01 - Gas consumption equipment and gas burning appliances in buildings - came into effect on 1 August 2013. Most changes are in the chapters that address the placement of gas appliances and air supply for combustion and ventilation and safety of gas appliances in version B. In this article will be mentioned and possibly commented on the most important changes.

We require that heat losses be equal to the currently supplied heat output, in an ideal event. However, this process is unsettled in time and we try to react precisely as best to the given changes of conditions through processes of the heat output control. It is necessary to deal with the dynamic behavior of heating surfaces, generally, to be able to achieve the most efficient control. The dynamic behavior is understood herein as the reaction towards the invoked control intervention. Authors are engaged in the dynamic behavior of radiators with local quantitative control through the thermal control valve fitted with the head with the liquid charge (hereinafter the “TRV” – Thermostatic Radiator Valve), in their contribution.

Ministry for Regional Development issued Decree No. 372/2001 Coll., in accordance with the provisions of the Energy Act lays down rules for allocation of the costs for heat energy for heating and costs for supply of hot service water to final consumers. Currently, the Ministry is preparing an amendment to these rules.

The joint program to promote the replacement of boilers is spreading to various regions of the Czech Republic. The aim is to reduce subsidies to air pollution from small combustion plants using solid fuels. Refers to the local heating of the heat output of 50 kW. The subsidy is provided to the various types of boilers and applies only to the replacement of existing manually filled with solid fuel boilers with new efficient low-emission sources.
