When operating domestic gas boilers, often there are problems with temperature control. Manual adjustment using a tap is time consuming and does not always allow you to set the desired value. The installed room thermostat for a gas boiler helps to solve this problem. Due to this modern device, you can easily install and maintain the desired temperature conditions indoors.
Classification of room thermostats
The room temperature controller for gas boilers is divided into several types, they all differ from each other by the principle of operation, device and method of connection.
Depending on installation
By the type of connection, the devices can be wired and wireless. Wired thermostats must be connected using wired circuits consisting of cables. They are connected to heating boilers through cable bundles. Such installation is considered difficult and time consuming.
Wireless devices are considered more modern, they emit signals in the form of waves, due to which the device is operated. Wireless-type regulators consist of two units, one of which is the thermostat itself and is installed in the room, the second is located near the boiler and connected to it using wires.
By type of sensors
In appearance, the room temperature sensor for a heating boiler can be simple or adjustable. The device of the first type is a standard temperature controller in which you need to set the temperature mode manually. The device of the second type is considered more complex in terms of design and control circuit. It has advanced functionality and makes it possible to set the air parameters for every day. It can be programmed hourly or in another way, which makes it possible to save fuel costs.
Selection rules
In order not to make a mistake when choosing a device and purchase the right model, it is better to adhere to the advice of specialists. If the boiler and thermostat are from the same manufacturer, the risk of possible inconsistencies and breakdowns will be minimized. For a powerful boiler, a thermostat of any type is suitable, it is better to choose an option with simple functionality to the standard version.
Before buying the device, it is worth calculating the technical parameters in advance in order to avoid equipment downtime. When installing a powerful device, you may need to replace the wiring, this issue must be discussed with a specialist in advance.
Purpose and characteristics
Any room thermostat for a modern gas boiler helps to heat the room to the desired temperature, regardless of its level inside the room. Thanks to such a device, the owner of the house does not feel the daily weather changes on himself, since the temperature regime adapts automatically. Externally, the device looks like a closed type siphon with a gas mixture or liquid inside.
The device’s filler responds to temperature changes and affects the movement of the rod closing contacts during increase and decrease of the mode. The design of a standard thermostat includes a highly sensitive element and a contact group with a regulator. The device can turn on and off the heating system in standalone mode and perform other functions in accordance with the specified parameters.
Connection and installation of the regulator must be performed according to the rules so that its operation and signal supply to the boiler are carried out correctly. This task is best entrusted to specialists.
Advantages and disadvantages
The temperature regulator for a gas-fired boiler is not a mandatory part of the heating system, but it is difficult to do without it in large houses and apartments consisting of several rooms. Owners of such devices note their undoubted advantages:
- compliance with the established temperature regime, which allows you to create a comfortable atmosphere in the house or apartment;
- full automation of the heating system;
- reduction of gas consumption by the boiler through the use of the device.
The disadvantage is the need for cable laying for wired regulators. The easiest way to do this is at the stage of building a house. The cost of the device is also considered a minus, modern devices are quite expensive.
Operating principle
The main purpose of the thermostat after connection is temperature control in automatic mode. Such a device allows you to save time, connect a gas boiler and configure its operation according to personal needs. During the operation of the boiler, the microclimate in the room is regulated by changing the temperature of the heat carrier. When it approaches the desired indicator, the boiler turns off, then turns on again. If the outside temperature changes, the parameters of the heating system must be manually adjusted.
Manual adjustment of the boiler requires additional time and attention, in this mode, the start-up and shutdown of the unit occur more often than necessary. Also, a circulation pump continues to operate in the process, increasing energy costs and total heating costs. The temperature controller allows you to solve both problems. It has sensors that monitor the temperature of the air in the room, not the water in the boiler, so the unit is turned on and off instantly when it deviates from the set mode.
Programming the controller makes it possible to set the desired threshold for the sensor to operate. Also in the device, you can set the delay time for turning on or off the boiler, which helps to reduce the likelihood of the device starting when the temperature drops briefly.
Operation tips
When choosing a wired controller, it is worth checking in advance all the wiring associated with its installation. Ideally, it should be hidden. This will help reduce additional costs. Before buying a device, it is better to study the prices of affordable options, since both expensive and cheaper thermostats are available on the market. Those who want to save money and connect an inexpensive device should stop at a mechanical device. It is enough to configure it once a day; in reliability it is not inferior to automatic counterparts.
To reduce heat loss, it is recommended that thermal insulation work be carried out before purchasing the necessary heating equipment. The choice of the device should be influenced by the area of the room in which it will be installed, and the planned temperature regime. It is recommended to buy a gas boiler and a regulator from the same brand, which will allow for installation and setup of the device in a simpler scheme. If this is not possible, it is worth considering that the work will take more time, and the services of the installation wizard will cost more.
