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.
Less experienced HVAC field service managers sometimes tend to have difficulties in identifying the causes of technical problems that common practice brings. The table in the article can be used both ways – to find the cause of the problem or use it as a basis for a maintenance plan designed to prevent the faults and equipment failures.
The thermoelectric transformation of waste heat into electric power is considered to be a promising technology enabling to enhance electric efficiency of current energy processes, fuel saving and emissions reduction. The submitted paper deals with the construction of thermoelectric generators, current thermoelectric applications and their potential utilization.
The study 2013 was focused on proving or disproving the legitimacy of commonly recommended nonparallel heating with individual heating mode, elected by users of the flats in apartment buildings. The result is important knowledge for the fields of main building production, heating, heating regulation, centralized heat supply and for users of residential units, whose thermal comfort and heating economy are dependent on the heating of their neighbor.
In recent years, there are significant technical and legislative changes in the field of thermal energy, efficiency of its production, distribution and use. The legislation went so far that it begins to interfere with the rights of users (consumers of heat). This is despite validity of the rules heating, where are relatively well established technical requirements for the design, supply and installation of heating systems, their regulation and compliance with temperatures in heated rooms. This happened on the basis of the rules that began to budgeted costs for consumed heat in a way that does not correspond to physical principles and real heat transfer and requires it in this case controversial obligations (Decree No. 372/2001 Sb., Act 318/2012 Sb. and the Act 67 / 2013 Sb.).

In practice we constantly fix difficulties in applying the conditions for the correct placement of appliances category B, that take away combustion air from the sorrounding of the appliance and the flue gas is removed through the flue and chimney above the roof. It is important to mention that this category of appliance participates most in flue gas poisoning including poisoning with fatal aftermath, occurring in tens of cases in the Czech Republic for the year. It is caused by the incorrect application of regulatory requirements, ie in particular the TPG 704 01.
The emissions trading scheme, EU's flagship climate policy tool, is at a turning point. With the price of carbon hovering way below €5 per tonne and a glut of permits on the market, something must be fixed or the instrument will turn to dust. As a first step towards correcting the problem, the European Commission has proposed a measure to withhold pollution permits temporarily, a process called ‘back-loading'. Back-loading appears harmless enough as all withheld allowances would re-enter the market before the end of this decade. Therefore the European Commission and many stakeholders recognise that structural measures are needed so that the ETS would support the transition towards a low-carbon economy.

Sales of heat sources in the Czech Republic has in the last few years permanently decreasing trend. Stems from the data collected by the Association of heating technology (APTT). In the following, we bring evaluate the results of annual sales of heat sources processed on the basis of information obtained from the producers of heating technology.
Emission limits for small combustion devices are becoming stricter. So far, the manufacturers of these devices successfully meet these limits by primary measures, but in the future we can expect greater use of secondary measures. The article describes the advantages and disadvantages of the use of catalytic converters and results obtained on a real combustion device.
