Heating a house with gas guarantees high comfort both because of the quality of such heating and the fact that its use does not require maintenance. Moreover, it is an environmentally friendly solution. What else should you know about gas installations? We invite you to read.
Despite numerous advantages of gas heating, some people have doubts about the safety of gas installations. There are also concerns connected with the costs of their installation. First of all you need to find out, whether gas installation is possible in your building, because not every situation allows for installation of such a system. The project of installation and its assembly should be made only by professionals with appropriate authorizations in the scope of gas installations. See what else you should know about gas installations and what kind of installation you should choose for your detached house.
Types of gas installations
Gas is one of the so-called conventional energy fuels. It is particularly popular among private investors. In detached houses, gas heating systems are used to heat the living space, domestic water and, to a large extent, the kitchen hobs
Which form of gas heating system is right for your home?
Due to the form of supplied gas the heating installation can have two forms, these are:
- natural gas – this form of heating is only possible in a situation where there is a gas installation network in the vicinity of your house;
- LPG – this is liquid gas stored in a special tank located outside your house. This method of heating is quite expensive, but hassle-free when it comes to its operation.
Building a gas installation
In the case of a single-family home, the gas installation is made up of a system of pipes and devices that are run outside and inside the building. They include:
- connection led to the gas pipeline,
- main tap,
- distribution inlet,
- gas cabinet with a gas meter,
- utility pipes directed to gas appliances.
Gas boiler room
One of the advantages of gas boilers is that they do not occupy much space and do not require maintenance. Moreover, the place where they are installed remains clean. In the case of single-family houses, gas boilers are usually wall-mounted devices of small size. The heating power of the boiler is important. In houses, the most common are 30 kW boilers, which we can place on any floor (including the basement). The most recommended solution is to place the gas installation in a separate room
Types of gas boilers:
- condensing boilers – these are currently the most recommended gas boilers; they recover heat from water vapour;
- low-temperature boilers – such boilers protect the installation and allow reduction of heating costs;
- boilers with open combustion chamber – in case of such boilers, the oxygen for combustion is taken from the room, so the boiler has to be installed in a room no smaller than 8 sq.m., with fresh air inflow through a hole of at least 2 sq.m. and a gravity ventilation grate of the same size
- boilers with closed combustion chamber – may be placed in any room not smaller than 6.5 sq. m, with gravitational ventilation finished with a grate of 2 sq. m
Connection to the gas network
In order to obtain a permission to make a connection to the gas network, we have to apply to the gas supplier. The next step is to submit a special application specifying the conditions of connection. The application should be accompanied by a map of the building (with the marked location of the gas cabinet) for information purposes and a copy of a document confirming the legal title to use the premises, as well as a statement of ownership. After submitting the application, a project of gas connection is prepared. It is also necessary to submit a construction notification to the appropriate authority (e.g. the starost’s office).
What are the costs of gas heating in a single-family house?
When choosing a heating system for our house one of the main issues to consider is the cost of heating related to the particular type of system. What is the situation with gas heating?
Below we present a cost calculation for gas heating in case of a 150 sq.m. detached house heated with a gas condensing boiler, taking into account that the heating season in Poland lasts about half a year. The comparison takes into account energy consumption for heating, ventilation and hot water preparation. The energy consumption limits set by the ordinance on Technical Specifications (TS) were followed.
|Standard in force in a given year (WT)||Gas consumption per year (kWh)||Total cost of gas consumption for 1 year (PLN)|

The list includes consumption of the so called final energy – energy delivered to the borders of the plot – it is this energy that we pay for. Given values are approximate, the real demand for heat usually turns out to be higher.
