Equally important, however, are also possibilities modulation boiler output, therefore, to what extent and in what manner it is possible to control the output of the boiler. High-quality gas boiler can be controlled from one in nine maximum performance, "said Švantner.
The construction of the heat exchanger
Exchanger in which heat energy is transmitted into the combustion gas heating water, are very critical components of the boiler, therefore, greatly influences its life. Always therefore pays interest on his design and quality. Exchanger according Švantner be made of steel of sufficient thickness. For example, exchanger body with gas boilers made from one piece of steel pipe wall thickness of 0.8 mm is virtually indestructible and can be, if necessary, easy to clean.
Connecting to a smart home
Increasingly, households appear different smart thermostats and other smart control or switching elements that allow, for example, precise temperature settings by time of day or a remote control heating via tablets and mobile phones. Their function is also important fuel savings by optimizing the settings for each installation. Modern gas boilers therefore provide the ability to connect various controls, as well as easy connection to the system of so-called smart homes. It's also a power control using an electric signal 0-10 V or support OpenTherm interface to connect smart thermostats. Last but not least also the possibility of weather-compensated control, thus setting according to external weather conditions. Of course there should be a separation of power control boilers for heating and hot water.
Design cabinets boiler dimensions
Design and embodiment of the housing is best compared to the other parameters of the furnace may seem secondary issue. Proper design of the cabinet, however, has many advantages, such as smaller size, through which the device can be installed also in tighter spaces. For ease of service is good, if the boiler casing easily removable, all three walls. For the case of installation in residential premises, when there is a utility room, a very important parameter too low noise devices, which will be to the people disturbing element and will not reduce the quality of housing.
