Few things are more crucial to keeping our homes warm and comfortable than a dependable heating system. And a gas boiler is often the central component of contemporary heating systems. These appliances, which heat the entire house and provide hot water for baths and showers, are the workhorses of countless households. Nonetheless, meticulous attention to detail is necessary for both installation and upkeep of a gas boiler, particularly with regard to the piping or "strapping" system.
We’re going to get into the finer points of strapping a gas boiler with two circuits today. Now, try not to be intimidated by the technical jargon. The arrangement of pipes that supply and return water to and from the boiler is essentially referred to as the strapping. However, why is this significant? Imagine it as your home’s heating system’s circulatory system; if it’s not set up correctly, you may experience a variety of safety and efficiency problems.
The capacity of a two-circuit gas boiler to heat water for your taps as well as the water that runs through the radiators or underfloor heating system in your house is one of its main advantages. This dual purpose raises the bar for complexity in the strapping procedure. To ensure optimal performance, each circuit must be carefully planned and installed; it is not enough to simply connect a few pipes.
There are a few key factors to take into account when strapping a two-circuit gas boiler correctly. First of all, the best piping arrangement will depend largely on how your house is laid out and where the boiler is located. It is necessary to consider factors like the distance between the boiler and the farthest radiator and any barriers or impediments in the path.
In addition, the longevity and safety of the piping depend greatly on the materials chosen. Using pipes and fittings that can resist these temperatures and pressures without corroding or leaking is crucial because gas boilers operate at high temperatures and pressures. Because of their longevity and resistance to corrosion, materials like copper and stainless steel are frequently used.

Difference from a single-circuit boiler
Boilers with two circuits feature a separate circuit for heating water for water supply. It is intended to give users hot water in addition to heating, unlike a single-circuit boiler.
The main task of a single-circuit boiler is qualitative and fast heating of premises. The boiler contains only one coolant circuit. The principle of its operation is simple: the coolant of the gas boiler is heated and circulates through the pipes installed in the room. The peculiarity of this equipment is its simplicity, even a layman can easily understand the operation of this boiler and in the case of a simple breakdown to repair independently. In addition, this type of boiler is equipped with many sensors that simplify the control of the heater. The parameters are set automatically, depending, for example, on the outdoor temperature. It is also worth noting the long service life of these boilers, the presence of an automatic safety system and the optimal mode of energy consumption.
Two-circuit gas boilers have a more complex structure, due to the presence of two heat exchangers. To their piping are added as well as water supply circuits. One heat exchanger is responsible for heating the room, and the other ensures the availability of hot water. The advantage of this boiler is its versatility. It is quite compact compared to other types of heating equipment with the same functions. In addition, the purchase of a two-circuit boiler will be much cheaper than the purchase of a single-circuit boiler together with a boiler. The piping of a two-circuit boiler helps to save money on heating, because basically the boiler heats exactly the amount of water that is needed at the moment preventing the cooling of excess water.
The main consideration when choosing a boiler should be its intended use. A single-circuit boiler is appropriate if all you need to do is heat the space and you don’t require hot water. On the other hand, if you still find that having hot water is essential, a two-circuit boiler is the most cost-effective and useful option.
Room requirements
Utilizing gas boilers and other heating appliances entails a constant risk of fire hazards. Manufacturers expressly govern the equipment’s operating guidelines in this regard, and it is highly undesirable to violate these regulations. Gas equipment installation comes with specific requirements and conditions, as does the room where it will be installed. Initially, gas boilers that fulfill the following specifications should be installed in any room (kitchen, hallway, or bathroom), according to manufacturers’ recommendations.
- The ceiling height should not be less than 2.5 meters, while the area of the room should not be less than 4 square meters;
- To the boiler must be provided free access, not less than 1.25 meters. at the front and 0.7 m. on the sides. A wide doorway must be provided, at least 0.8m in the front and 0.7m in the back.
- The room should have several window openings with an area of at least 0.03 m 2 per 1 m 3 of the room, to ensure good illumination.
- Ventilation system in the room with a gas boiler is a prerequisite for installation;
- In addition to ventilation, an important part of the two-circuit boiler piping is the cold water piping system. through the room (if the second circuit will also be used);
- The wall covering in such a room should contain non-combustible materials with protection against accidental fire.
Connection diagram of a two-circuit boiler
If the gas service has already connected the boiler to the gas mains, then strapping a two-circuit boiler can be completed independently. Following receipt of the project documentation from the gas service, you can start by designing the plumbing layout, installing the boiler, connecting the required pipes, setting up the power supply, and arranging the chimney.
The boiler has multiple spigots arranged symmetrically to ensure their connection to the water and heating supplies because it has two circuits. The connection scheme of a boiler to a hot water supply is as follows: the boiler’s passport will provide more precise information. Generally, the hot water supply is connected to the right and the cold water supply to the left. The location where the branch pipe connects the boiler to the return flow should have a coarse filter installed in order to shield the boiler from debris and prolong its service life.
It is imperative to install shut-off valves on every pipe subsequent to the filter installation. In the event that the boiler fails, this will lessen the need to empty the leftover water from the pipes and make boiler maintenance simpler.
In setting up a two-circuit gas boiler for your home, there are some key points to consider. Firstly, understanding the necessity of separate circuits for heating and hot water ensures efficient performance. Secondly, proper installation of the piping system is crucial to maintain the integrity of both circuits, preventing leaks and ensuring consistent heat distribution. Thirdly, ensuring compatibility with the boiler"s specifications and local building codes is essential for safety and effectiveness. Additionally, regular maintenance and servicing are vital to keep the boiler running smoothly and prolong its lifespan. By paying attention to these features and taking necessary precautions, you can optimize the performance of your two-circuit gas boiler and enjoy reliable heating and hot water in your home.
Strapping of a two-circuit boiler with a boiler
All heating equipment has a strapping system in place to ensure that the boiler runs properly and that coolant is transported through the pipes. Each type of boiler requires different strapping depending on its location and whether or not it has auxiliary equipment. However, there is a general scheme that serves as the foundation for additional strapping arrangements.
If the boiler is connected a lot of taps, showers, and baths. To provide each of them requires a large boiler power. But even if there is, the temperature of warm water will be different in each of the taps and waiting for the water to heat up, a person will use a large amount of water, which is not very economical. To solve the problem, a special boiler is connected to the water supply system. Usually the connection is made by means of a distribution manifold, which distributes the hot heat carrier between the heating system and the boiler. To avoid overconsumption of energy for water heating, special equipment in the form of a pump with a thermostat is also used. If the water in the boiler cools down, the thermostat signals the pump, it switches on and the water starts to heat up again. When the water is heated to the required temperature, the pump is switched off.
Selecting a storage water heater would be a great alternative to using a boiler. It is connected to the water supply point and the two-level boiler. Compared to the boiler, the water heater has several benefits, including simplicity and cost-effectiveness as well as an increase in the gas boiler’s resource. It lasts far longer, uses less energy, and is rarely turned on unnecessarily.
