Tips when cleaning the heating circuit in your home with Reformia
The average price for heating maintenance is around 100-150 € and should always be done by an authorized professional.

1. Establish a maintenance contract with a specialized company
It is the most convenient and effective way to ensure your heating is reviewed properly. The contracted company is responsible for notifying the user when the winter startup is approaching so the system is in perfect condition for startup. Additionally, if there were any problems, they would be covered by the contracted coverage and guaranteed professional attention.

2. Inspect the heating at least once a year
It is important to inspect the heating every year, preferably before startup. This way, small problems that can cause the system to lose efficiency can be resolved, such as when the circuit or radiators have air or the boiler does not have adequate pressure. Not only will you use less energy, but your heating system will remain in better condition for longer.

3. Check the condition of the heating yourself
Although a complete and thorough inspection of the heating is something that only specialized professionals can do, there are small tasks that anyone can do that contribute to the system being in optimal condition. Checking that the boiler pressure is adequate, that the radiators heat as they should and have no leaks, or that the thermostats are properly programmed and working without problems are some of them.
The average price for heating maintenance is around 100-150 € and should always be done by an authorized professional.

Steps to flush your heating system
The average price for heating maintenance is around 100-150 € and should always be done by an authorized professional.

1. Contact an authorized installer
First, find a qualified heating system installer who specializes in circuit cleaning services. Ensure they hold proper certifications and have experience with heating maintenance. A certified professional will guarantee that the cleaning is performed correctly and safely.

2. Request a quote and check availability
Request quotes from multiple installers for heating circuit cleaning services. The average price is 215 €, ranging from 80 € to 350 € depending on the type of service. Compare offers and availability to find the best option within your budget.

3. Prepare access to your system
Prepare access to your heating system before the appointment. Clear spaces around radiators and pipes, and ensure the professional can easily access all circuit points. This preparation facilitates the work and may prevent additional cleaning costs.

4. Drain the heating circuit
The technician will completely drain the heating circuit, removing all water from the system. This step is essential before thoroughly cleaning pipes and radiators. The drainage must be done carefully to avoid damaging the installation.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Type of heating system
Price varies significantly depending on whether it's a gas boiler, oil boiler, heat pump, or radiator system. Each technology requires different cleaning and maintenance procedures that affect the final cost.
Age and condition of the installation
Old boilers or those with heavy lime scale and dirt buildup require more time and specialized chemical products for cleaning, increasing the budget compared to well-maintained systems.
Complexity of the piping network
Homes with extensive heating circuits, multiple zones, or installations with many radiators require more working time and a larger quantity of descaling product, raising the total cost.
Geographic location and travel
The technician must travel to your property, so rural areas or locations far from urban centers may have additional travel costs compared to metropolitan areas.

However, for maintenance work to be truly effective, it is necessary to thoroughly inspect each component of the heating system:
Budget examples
- High energy consumption due to overwork of the equipment.
- Premature wear of equipment and system components.
- Breakdowns that could have been avoided had symptoms of malfunction been detected early.
- High repair costs, as problems are detected sooner.
Performing regular maintenance on your heating system ensures it operates at full capacity, thus improving its energy efficiency. It should be kept in mind that with any boiler problem, it will be working without achieving the desired effect, consuming wasted energy. Therefore, a heating inspection can reduce your bill by 10% - 20%.
Safety
Another advantage of keeping your heating up to date is the safety it provides to your home. Since this way proper operation is guaranteed in all aspects. Avoiding not only functional problems, but also those related to the safety of the building's occupants.
- Boilers: pressure, tightness, combustion, flame, etc. must be checked.
- Heat pumps and accumulators.
- Radiators: leaks, faulty connections, or presence of air.
- Circuits: leaks or presence of air.
