Boiler connection to a double boiler
To ensure a private or holiday home hot water in the presence of a two-circuit boiler in the building often requires additional connection to the boiler water heater. If the boiler is not yet installed, the best option would be to buy a single-circuit boiler, which is connected to the boiler indirect heating, but in a situation where the house has a two-circuit boiler and replace it with a single circuit does not work, you should intelligently connect to it additional water heater.
Materials
To arrange the hot water supply in this way, you need to prepare:
- Boiler
- Circulation pump
- Two-circuit thermoblock
Wiring diagram
The heating circuit of the water heater is looped to the second heat exchanger of the gas boiler. At the same time the inlet pipe of the heater is connected to the first pipe of the boiler heat exchanger and the outlet pipe of the boiler is connected to the second pipe. Water from the water supply will no longer enter the boiler heat exchanger, and the boiler, and from there flow into the hot water system.
If an electric boiler is connected to a two-circuit boiler, the scheme will be almost the same. In this case, the water supply network is connected to the first branch pipe from the second heat exchanger, and its second branch pipe is connected to the boiler. From the electric heater to the faucets derive the pipe, which will supply hot water.
Stages of work
- The first stage will be the installation of the boiler. The heater must be mounted in close proximity to the heating boiler. This is important for linking these devices with the necessary automatic device.
- The second stage of the work is to combine the boiler and the boiler in a common scheme. To work fully, the heater should not take on most of the heat, as this will lead to problems with heating the house. The optimal solution is to install a circulation pump, which has an automatic.
- The final step is connection of the thermoblock.
Approximate cost of the work
Work on connecting any water heating device to the gas boiler should be entrusted to professionals. The cost of their services will depend on the actions required. For example, the design of the boiler room costs from 300 rubles, for the installation of the boiler must be paid from 3000 rubles, and for the installation of the pump group - at least 3300 rubles.
