It might be necessary to install two boilers simultaneously and connect them to a common network in order to modernize the heating system in a private home. In this situation, what order should be followed? If joint use of gas with solid fuel, electric boiler, or heating equipment running on liquid fuel is required, it is important to consider how to connect two boilers in one system.

Lack of capacity. Incorrect calculation of the equipment or additionally added living space can lead to the fact that the boiler capacity may simply not be enough to maintain the normal temperature of the coolant.
It is evident that connecting two heating boilers using different fuel sources is feasible. This may also be the result of an urgent need brought on by the equipment’s low output.
How to connect two gas boilers in parallel
For connecting gas and any additional water heating equipment, there are two methods. One heating system can have two boilers connected to it:
-
Sequentially – in this case one unit will be installed after the other one. The load in this case will be distributed unevenly, as the main boiler will constantly work at full capacity, which can lead to its rapid failure.
Installing a controller and creating a cascade control scheme are requirements for parallel connections. Only a qualified specialist in each unique situation can provide an answer to the question of how to connect two gas boilers.
How to connect two boilers – gas and solid fuel boilers?
It is easier to combine gas and solid fuel boilers into one system, but in order to do so, you must consider the key characteristics that set these two types of equipment apart from one another.
It is possible to install gas and solid fuel equipment models in a network in a sequential manner. In this instance, the primary source of heat supply will be the TT boilers.
Their working premise is that the gas equipment will only be turned on for heating if the main unit’s operation is rendered impossible for any reason. Naturally, if such a function is available, the task of heating water is also typically assigned to the gas boiler. When designing a system of this kind, these features must be considered.
Additionally, the chosen plan must be coordinated with the gas utility in order to secure all required permits, including those for the connection project and technical specifications.
How to combine gas and liquid fuel boilers
It is vital to establish the prerequisites for this kind of connection in order to ensure the simultaneous safe operation of both kinds of equipment. The following actions are required in order to achieve this goal:
-
To carry out installation of a common system of control over the operation of water-heating equipment. The joint use of liquid-fuel and gas boilers implies the installation of a common automatics. It in turn is connected to the controlling sensors, which signal to turn on in case the main heat source stops working.
Depending on the needs of the customer, a series or parallel connection is made. After being created in the project department, the circuit diagram and plan are coordinated with the gas utility service.
Advantages of installing several boilers in one network
Install two boilers simultaneously: wall and floor boilers might be required if the room’s size has significantly expanded due to construction. It might not be sufficient to heat additional rooms with a larger area, even if the equipment was originally purchased with a power reserve. In this instance, a second boiler is installed and linked to the shared heating infrastructure. This solution has the following benefit:
-
The possibility of simultaneous control over the operation of all equipment.
Ensuring effective heating and appropriate insulation are essential for a functioning home heating system when connecting two boilers in parallel. Care must be taken when connecting the boilers to guarantee even heating throughout the house without stressing the systems. To keep the boilers from interfering with one another’s operations and to ensure even heat distribution, a hydraulic separator must be installed. Furthermore, sufficient insulation in the home’s piping system and structure helps to minimize heat loss, enhancing energy economy and lowering heating expenses. Homeowners can ensure warmth and comfort throughout their house while maximizing the performance of their dual boiler system by following these steps.
Experience has shown that it is feasible to install two or more boilers in a network at the same time. The overall performance and efficiency drastically decrease with each extra element. As a result, there is absolutely no benefit to installing four or more water heating units at the same time.
