As the seasons change, it’s crucial to get your house ready for the winter. One of the things you should do is preserve your gas boiler if you’re not going to be using it in the summer. Your gas boiler will stay in good working order and be prepared for use when needed if you disconnect and store it appropriately. We’ll walk you through the process of disconnecting your gas boiler safely and effectively for preservation in this guide.
The importance of maintaining your gas boiler must be understood before beginning the disconnection procedure. Every household that owns a gas boiler makes a significant investment, and regular maintenance can guarantee optimal performance and increase boiler lifespan. Long-term periods of inactivity can cause corrosion, damage, and problems with efficiency. You can avoid these problems by properly disconnecting and maintaining your boiler.
Making sure everyone is safe is the first step towards disconnecting your gas boiler for preservation. When using gas appliances, safety should come first at all times. Start by cutting off the boiler’s gas supply. Find the gas shut-off valve and turn it to the "off" position. This valve is usually located close to the boiler. By taking this action, gas leaks are avoided and a secure workplace is maintained.
The boiler itself needs to be shut down after the gas supply has been safely cut off. To turn off the boiler, most contemporary gas boilers have a power switch or control panel. If this is something you’re not sure how to do, consult the boiler’s manual. During the preservation process, the chance of an unintentional ignition is decreased when the boiler is turned off.
It’s time to remove any leftover water from the system after turning off the gas supply and turning off the boiler. During the winter, water that remains in the pipes and boiler can freeze and cause damage. Find the drain valve on the boiler and, if needed, attach a hose to direct the water to an appropriate drainage point. Let the water run out completely by opening the valve.
It’s crucial to shield the boiler and its parts from rust and other damage after the water has been drained. Applying an appropriate preservation solution to the boiler’s interior surfaces is one method for doing this. During times when the boiler is not in use, these solutions are intended to prevent corrosion and maintain its good condition. Pay close attention to the preservation solution’s manufacturer’s instructions.
It’s time to seal the boiler and any exposed pipes after applying the preservation solution to stop moisture intrusion. Appropriate sealants or covers should be used to close gaps and shield exposed parts from the elements. This measure guarantees that the boiler is even better protected and maintained until it is required once more.
Step 1: | Turn off the gas supply valve. |

Whether the boiler can be switched off?
A common query from users at the start of the warm season is whether it’s necessary to turn off the boiler. Gas equipment, which includes engineering networks for the supply of gas, electricity, and water, is one of the objects of increased danger and needs to be kept in good working order at all times.
The device’s primary component is the boiler’s internal heating systems, which are composed of metal and are prone to corrosion from the inside due to O2 in the surrounding water and from the outside due to soot. In order to prevent corrosion processes during extended shutdowns, all manufacturers advise doing so. The kind of fuel used, the tap water’s quality, and the boiler pipes’ composition will all affect the type of preservation. The unit’s operating instructions include a detailed description of the preservation technology, which service staff should adhere to to the letter.
There are three methods for conserving boilers: the dry, wet, and overpressure methods.
- Dry method is used when it is necessary to shut down the boiler for a long shutdown in the cold season at negative temperatures. It consists in the fact that the device is completely free of water and with open air vents dried by an external source, for example, a blower boiler heating surfaces from residual water.
- Wet method is used when there is no danger of low temperatures. In this case, the unit is filled with water with alkaline reagents that create a uniform protective film on the surface of the metal.
- The overpressure method consists of maintaining pressure in the unit disconnected from the gas, which prevents oxygen from the air, which is the main aggressive corrosive corrosive element, from entering the unit. In this method, before the boiler is turned off, it must be filled with purified water from filters.
Ensuring that the device’s fittings and headset are completely tight is necessary for all of the aforementioned preservation techniques.
Shutdown rules
Every boiler unit brand has a different sequence for shutting down, but generally speaking, there are several stages. The single- or double-circuit devices’ intended use and design determine the technological method of stopping the unit. During the summer, the two-circuit boiler will be partially shut down; that is, the heating equipment will be disconnected, but the DHW load will stay operational.
Phases of a unit shutdown in general:
- The gas valve is switched off. There are 2 variants – only on the main burner or jointly on the main burner and the igniter.
- In the first case, the knob is turned clockwise and set in the "ignition" position, the main unit will be shut down, but the pilot unit will continue to function.
- In the second case, the knob is turned clockwise to the "off" position, which cuts off the gas to all burners.
- You can turn off the auxiliary equipment fans, smoke extractors in 15-20 min after shutting off the gas.
- Stop the circulation pump after cooling the mains water to room temperature.
- Disconnect the power supply to the unit.
- Preserve the unit according to the manufacturer"s instructions.
- Disconnecting a two-circuit unit in the summertime follows a slightly different procedure.
- At first, the heating line is shut off with a three-way valve, in this case the coolant from the heating system goes to the secondary DHW boiler.
It is essential to preserve your gas boiler when it is not in use to keep it long-lasting and efficient. Whether you’re turning off your heating system for the summer or a longer trip, making sure your boiler is properly preserved will guarantee that it’s in excellent shape when you need it most. You can safely and successfully disconnect your gas boiler by following a few easy steps.
First and foremost, you must cut off your boiler’s gas supply. Find the shut-off valve, which is often located along the gas line or close to the boiler, and make sure it is securely closed. This is an essential step to avoid any hazards or gas leaks while the boiler is not in use.
The boiler system’s water should then be drained. To start, turn off the boiler’s electricity to avoid any mishaps. After that, find the drain valve close to the boiler’s bottom and connect a hose to it to safely divert the water away. Let the water run out completely by opening the valve. This lessens the chance of corrosion and sediment accumulation inside the boiler.
It’s time to deal with any leftover water in the pipes and radiators after the water has drained. Until the system is completely dry, flush out any leftover water using a pump or gravity. In order to avoid frozen pipes and possible damage during the winter, this step is essential.
Lastly, to prevent rust and corrosion of the internal components during storage, think about using an appropriate boiler preservative. To guarantee complete coverage and efficacy, carefully adhere to the manufacturer’s instructions when applying the preservative.
These procedures will help you disconnect and store your gas boiler safely, keeping it in top working order until you need it again. In addition to extending the life of your boiler, regular maintenance and preservation also lower long-term costs and increase energy efficiency.
Maintaining the longevity and efficiency of your gas boiler during inactivity requires preservation. First, cut off the gas supply and the boiler’s electricity in order to disconnect your gas boiler for preservation. The boiler and its pipes should then be drained in order to stop any water from freezing and causing damage. Because methods can differ, it’s imperative that you adhere to the manufacturer’s instructions for your particular boiler model. In addition, if you’re unclear of any steps, think about speaking with an expert. Maintaining your gas boiler properly helps avoid future expensive repairs and guarantees that it will be ready to heat your house effectively when needed.
