An effective heating system is essential for keeping your house warm and comfortable during the winter. A double-circuit gas boiler is a common choice among homeowners. This kind of boiler is a flexible and affordable option because it not only heats your house but also heats water for household use. However, some people may find it difficult to connect a double-circuit gas boiler to their heating system. This post will explain how to connect your boiler properly for best results by breaking the procedure down into manageable steps.
It is imperative that you comprehend the fundamental workings of a double-circuit gas boiler before beginning the connection process. A double-circuit boiler has two distinct circuits: one for heating the house and another for heating water for taps, showers, and other household uses. This is in contrast to conventional boilers, which only heat water for radiators or underfloor heating. Because of its dual purpose, it’s a cost-effective option for homes trying to simplify their hot water and heating systems.
Having all the tools and supplies on hand is one of the first steps in connecting your double-circuit gas boiler to your heating system. This includes any extra parts needed for your particular setup, as well as pipes, fittings, and valves. To prevent any compatibility problems or installation mistakes, it is essential to verify compatibility again and refer to the manufacturer’s instructions.
The next step will be to evaluate your home’s layout and choose the best spot to install the boiler. It should ideally be positioned in a room with good ventilation and easy access for upkeep and repairs. Take into account additional elements like the distance from electrical outlets, gas and water supply lines, and other facilities. For both safety and effective operation, proper placement is crucial.
Now that you’ve decided where to put your boiler, it’s time to start the installation procedure. This usually entails integrating the boiler with your home’s hot water supply and connecting it to the pipes in your heating system. The particulars may differ based on the brand and model of your boiler, but generally speaking, the procedures entail attaching the inlet and outlet pipes, installing any required controls and valves, and checking the system for leaks and functionality.

How to connect a double -circuit gas boiler correctly
You can accomplish two goals with the installation of a double-circuit gas boiler: you can arrange the hot water supply for household needs and supply coolant for the home’s heating system. In other words, one boiler can handle two sufficiently significant issues. This explains why suburban village dwellers have been clamoring for such units lately.
Although connecting a dual-circuit gas boiler is not a simple task, you can do the installation yourself if you know what you’re doing.
The majority of these boilers’ models run in the mode that produces six liters of hot water in a minute. An excellent indicator, but it can only be used if the unit is connected and installed correctly. This heating device operates on the basis of the existence of two contours, each of which functions independently and separately. One of them supplies coolant to the heating system, while the other one serves the hot water supply system.
The main connection scheme
A double-circuit gas boiler must be tightly connected to multiple systems in order to be connected correctly:
- Heating, where there will be two pipe – the supply of the coolant and its return.
- Water supply, where cold water will be supplied to the systems.
- Fuel gas pipeline.
- Electric power supply, if control and regulation devices are installed in the boiler.
There is typically some issue with the final connection point. All you need for this is a socket. There is no need to wait for significant costs because the tablet level uses a significant amount of electricity.
Hanging the boiler on the wall should be done first. Note that the wall device is not suspended from the ceiling, as this would be counterintuitive given that the primary focus is on operating convenience. Special brackets are required in order to install a double-circuit gas boiler. Typically, they have a heating component. They are fastened to the wall with screws and plastic dowels, and there are two of them. The primary objective is to precisely position the brackets in a horizontal plane, so a level and plumb are required during installation.
You can hang on to the fasteners and the boiler itself once they are fixed to the wall. Please be aware that there is nothing complicated about this installation; you can complete all of the tasks with your hands.
Requirements for the room
The space where a dual-circuit gas boiler needs to be connected does not have any unique specifications. However, some guidelines are still in place:
- This room should have a window that can be opened at any time.
- The current ventilation is required.
- All pipelines should be carried out in the room, to which the unit will be connected. Particular attention – a gas pipe. A fuel consumption meter must be installed on it.
Every model of gas double-circuit boiler available today has the same connection diagram. If variations exist, they are solely due to where the boiler’s pipes are located. Still, this is fairly uncommon.
The nuances of the connection
The first step in the procedure is to install a cutting valve and a rough cleaning filter on the water supply system pipeline. This tiny but crucial gadget will guarantee that the water in the heating system is pure. It’s no secret that the low quality of the incoming water is frequently directly linked to the deposits found in the heat exchanger.
Take note! Using your hands to install a filter is not too difficult. Use a threaded connection to wind it onto the pipe pipe in order to accomplish this. The device itself has an arrow that indicates the direction in which the water will flow; pay attention to it. Don’t be unclear! Make sure the filter is wound onto the sealant. It might be a fum-oriented paint bag.
If the water supply needs to be blocked in order to fix the boiler, clean the filter, or replace it, a cutting valve will be required.
The pipes for the hot water for the asshole and the heating system are then connected. Additionally, nothing complicated about this situation exists, and the procedure is the same as it is for the water supply. Cutting cranes are attached to the boiler when they are installed. A ball-shaped cutting crane is preferable.
An internal circulation pump in the wall-circuit gas boiler’s construction ensures that heat is distributed evenly along the heating radiators. This is an essential device that needs a unique binding. Due to the energy dependence of the wall unit, cutting the electricity causes the system as a whole to lose thermal energy and becomes less efficient. Floor models are capable of operating naturally with the coolant circulating without the need for a circulation pump.
The gas pipeline is the final link in the connection process. The boiler should attempt to locate itself in a location that is closest to the gas pipe. Of course, modern gas hoses make it possible to complete the connection, and the fire safety service permits you to do so. However, a long hose cannot be set; it is preferable to carry the pipe to the unit’s installation location. You need to get in touch with a specialized business that is authorized to handle this kind of work because doing it yourself is not advised. Allow experts to handle gas pipe work.
What installation is required for a gas pipe? The crane and mesh filter come first. Through flanges or thread, everything is connected. Select the option that best suits your needs. An additional component is part of the system for connecting a double-circuit gas boiler. It’s a chimney here. The coaxial chimney is the best option if you want to install a wall option in your home. To accomplish this, you must drill a through hole in the wall that is the same diameter as the chimney. Behind the wall, the coaxial pipe is expelled horizontally.
The floor unit needs to have a traditional chimney that exits outside the roof. Due to the high power of these boilers, a large number of combustion products can only be handled by a vertical design. Please take note that the chimney should stick out from the roof by half a meter and should have as few bounces and turns as possible. And this is the very least.
Settings of the boiler
According to instructions for a double-circuit boiler passport, configuration should only be done by specialists. The unit checks the security and control units, sets the required operating mode, crimps the master, and shows the owner of the house all of this. Setting the modes is given special consideration because you will be doing this yourself in the future.
Conclusion on the topic
The room’s boiler room
As you can see, connecting a double-circuit gas boiler is not a particularly challenging task. It calls for paying close attention, following the precise steps outlined in the instructions, and adhering to all rules. One device contains multiple interconnected life support systems, so even the smallest error could compromise the unit’s ability to function as a unit. Thus, exercise extreme caution.
Installation of a gas boiler with two contours
This boiler is installed by gas service professionals most of the time. Still, this is an expensive process. As a result, home owners frequently choose to install and connect a double-circuit gas boiler to the heating system. You can do such things thanks to modern regulations. It is true that you must adhere to a number of rules and refrain from using the gas pipeline connection at the same time.
The entire installation procedure Dual-switch gas boiler The house can be broken down into these phases:
- Installation on the wall or floor.
- Connection of the heating system and the DIS system.
- Connection to the gas pipeline.
Installation rules on the wall or floor
The gas unit needs to be situated in a different room. which satisfies the subsequent criteria:
- There is a window that can be opened at any time.
- The presence of valid ventilation.
- The presence of gas and water pipes.
- The presence of a socket to ensure the operation of the circulation pump and electronics. Of course, it should be the end of a separate branch that moves away from the electric shield. This cable must be connected to a separate protective machine. In addition, grounding is mandatory.
- The distance between the main element of the heating system and other gas devices should exceed 20 cm.
- There should be no window near.
- The distance between the boiler and the outlet should be at least 0.5 m (at least such recommendations are given by manufacturers). In general, the further the socket from the boiler, the better. It is worth adding that some models have a power cable without a fork. This means that the wire must be connected with your own hands immediately to the circuit breaker placed in the electrical panel.
- The space between the side walls of the boiler and the adjacent walls or objects should be more than 15 cm.
- The wall, on which or near which the installation of the boiler is carried out, should be strong and covered with non -igniting substances. If the wall is one that can light up, it should be covered at least 3-mm non-combustible material. This is often noted in various videos.
Boiler fixation
The following procedure is followed when installing a wall boiler in a home:
- Study Manufacturer"s recommendations and select the optimal place in terms of safety and convenience rules.
- Fix the mount on the wall. Supposed with a boiler. To carry out its installation in the house correctly, you should use the level and slope. Very often, the mount is long dowels and hooks with threads at a longer end.
- In the place where the wall should cross the chimney. make a hole for him.
- Fix the chimney in the boiler. This process is performed very carefully, since the chimney is coaxial (not only carbon monoxide comes out through it, but also fresh air supplies). And this means that when making errors, air and carbon monoxide will not be able to circulate correctly, which will certainly lead to poor consequences.
- Hang the boiler on fixed mounts in the wall.
Installing a floor boiler is easier because all you have to do is use your hands to create a sturdy base on the floor and press the unit up against the wall.
In connecting a double-circuit gas boiler to your heating system, the primary aim is to ensure efficient heat distribution throughout your home while maximizing the boiler"s performance. It"s essential to start by understanding the components involved and their functions. Your boiler has two circuits: one for heating water for your radiators and another for providing hot water for taps and showers. To connect it properly, you need to integrate it seamlessly into your existing heating system, considering factors like pipe layout, pump placement, and control mechanisms. Proper insulation of pipes and the boiler itself is crucial to prevent heat loss and maintain efficiency. Additionally, ensure compliance with safety regulations and seek professional assistance if needed to guarantee a safe and effective connection. By following these steps, you can enjoy a warm and comfortable home while minimizing energy costs.
Binding scheme
Prior to consideration, it is important to note that every gas boiler with two contours has four water pipe pipes. There are two of them made to provide hot water. The house’s installed heating radiators receive water through a single conduit. Via a different route, to an indirect boiler that is a component of the hot water supply (DHW). Water from indirect boilers and radiators is intended to be returned via two additional pipes.
A double-circuit gas boiler’s connection diagram looks like this:
- Boiler.
- Ball cranes on four pipe.
- Security Group on a pipe supplying hot water to the heating system. Consists of a pressure gauge, a safety crane and an automatic air vent. These devices are in demand for floor boilers. As for most wall models, they already have them.
- Heating radiators.
- Expande tank on a pipe extending from the batteries installed in the house. In many cases, it is part of a system with a floor boiler. It can be added to the strapping with wall. This may be needed in cases where the extensor tank built into the case has too small sizes.
- Carriage filter on the same pipe. He protects the boiler heat exchanger from clogging with all sorts of elements. which carries water from heating radiators.
- Ball cranes on both sides of the filter.
- DIS pipeline.
- Return Pipe from DIS. A water pipeline pipe is also connected to it.
- Carrying filter.
- Magnetic filter. Allows you to get rid of rust and scale coming with a liquid from the water supply.
- Ball cranes from both ends of these two filters.
Connecting the boiler to radiators and DIS
The following order is followed when carrying out this process:
- They carry it out with their own hands Installation of ball valves on boiler nozzles. To ensure sealing on the thread on the pipes, they wound a pac from the pacli, fum tone or thread. It is worth adding that before fixing shut -off valves or filters, you always need to wind one of these elements on the thread of metal pipes. If it is planned to use polypropylene or metal -plastic pipes, you will have to solder and use special fittings. Features of these processes can be found in various videos.
- Connect the pipe to one cranes for supplying the coolant In the heating system installed in the house.
- If necessary, mount a security group.
- An expansion tank is placed on the return pipe of the heating system (of course, if there is a need for it).
- Install the ball valve and water purification filter. The latter must be mounted on a horizontal segment of the pipeline. You can also on a vertical pipe, however, in this case you will have to use a special version of the filter. It is installed in this position that the direction of the arrows depicted on it coincides with the direction of movement of the coolant.
- After the filter, put the second ball crane. These taps are necessary to facilitate the cleaning of the filter. They are blocked with their own hands and cleaned the filter.
- Connect the reverse pipe from the heating system to the boiler.
- Connect the "hot" DHW pipe to the crane located on the right pipe.
- A tap pipe is cut into the reverse line from the dowry. Of course, at the beginning of this pipe they put a ball crane. It will stop the influx of cold water after filling it with all the heating system installed in a private house and the hot water.
- A ball valve, a magnetic filter and a ball valve are placed on a reverse pipe from the hot water in front of the downside before entering the boiler.
The circulation pump was not discussed here. Boilers with dual circuit walls always have it. It is not required for floor boilers designed to have the coolant circulate naturally. if an already-existing natural circulation system. Then, in order to force the coolant to move, I would need to install two circulation pumps, one on the hot water heater’s reverse line and the other on the heating system’s reverse line.
Connection to the gas pipeline and installation of the chimney
The experts from the gas supply company should handle the initial procedure. First, they have to make sure that the boiler is installed correctly and that all requirements are met. Following the device’s connection, you will receive a document enabling you to operate a gas unit.
The necessity for this arises from the fact that all gas devices are hazardous and that if they are installed in the future, an explosive scenario might occur.
You must get ready in order to connect to the gas pipeline:
- Tap.
- Mesh filter. Will clean the gas, so the burner will not clog and will be able to function for a very long time.
It has already been mentioned in part regarding the chimney. discussed the Coaxial Smoke Pipe. It is typical of boilers with closed cameras, most of which are wall-mounted models. These cameras are also found in floor units. Nonetheless, the majority of them have an open camera installed. This indicates that air enters the combustion chamber from the room, and a sufficient thrust must be distributed according to demand. And to do this, you must build a tall chimney by hand.
The chimney is installed in this manner:
- Install a vertical pipe made of stainless steel. Fixing it with a special mount. Its height should be such that the upper end protrudes above the roof skate by 0.5 m. At the same time, they try to make as few turns and horizontal sections as possible. If you can’t do without the latter, then you cannot do more than 1 m longer.
- Connect this pipe to the boiler.
- All parts of the chimney that will contact with cold air are insulated. To do this, it is better to use basalt cotton wool.
- A special umbrella is placed upstairs.
