Gas Heating Maintenance

Care for safe and economical heating.

Gas heating is a complex system that is subject to high temperatures, pressure and mechanical wear. To ensure that the efficiency of your condensing boiler remains as high as you expect throughout its service life, you should adhere precisely to the maintenance intervals for a gas heating system.

Three reasons for regular maintenance

Gas heaters must be serviced regularly for three reasons:

  • safety
  • effectiveness
  • durability

A distinction must be made between maintenance and chimney sweep testing for the calorific value of gas heating. The chimney sweep only checks the safety of the chimney and compliance with the flue gas values. Some, but by no means all, defects can be identified from this.

Gas systems must be checked regularly for leaks. For safe operation, all components must be checked regularly for wear. But even if safety is not compromised, defective, worn parts or incorrect settings have an effect on efficiency and consumption. If you have your boiler checked regularly, you can be sure that the gas condensing boiler really does work as economically as it can.

It can also happen that the heater continues to work despite a malfunction and you may not even notice that there is a problem. This often results in unnecessary extra consumption and increased wear of individual parts. Over time, this can result in damage that is significantly more expensive than the cost of annual maintenance. Maintenance according to the manufacturer’s specifications is also important for a gas heater in order to obtain warranty claims.

What is part of the maintenance of a gas heating system?

When the maintenance date comes for the gas heating system, the boiler deserves the most attention. This starts with reading out the heating controller. Error codes and the number of burner starts and operating hours give important indications of defects or unfavourable setting of the heating control. A relay test is also carried out via the control unit and the intact circuit is checked.

This is followed by the mechanical steps, which make up most of the maintenance work for a gas heater. The heat exchanger must be cleaned and the condensate drain flushed. An important step, if a gas heater has been subjected to maintenance and then reassembled, is the gas and water tightness test.

Finally, ignition and monitoring devices and seals are tested and worn parts are replaced. The exhaust gas measurement follows at the end. Finally, the attentive installer will also check the function of the expansion tank.

The date for heating maintenance is of course outside the heating period and should ideally be scheduled at the end of summer. Then the system is ideally prepared to be put back into operation.

For gas heating, maintenance intervals voluntary or according to regulations?

It is often read that an annual inspection for gas heaters is required by law. However, although maintenance plays an important role in the operational safety of gas heating systems, it is controversial, even among experts, to what extent such a rule is really mandatory.

According to EnEV, maintenance is a legal obligation for gas heating systems. The corresponding passage can be found in EnEV §11 Abs 3: “Systems and equipment for heating, cooling and ventilation as well as hot water supply must be properly operated by the operator. Components with a significant influence on the efficiency of such systems must be regularly serviced and maintained by the operator. For maintenance and servicing, expert knowledge is required. The expert is the person who possesses the specialist knowledge and skills required for maintenance and servicing.” However, the maintenance interval is left open.

On the other hand, the technical rules for gas installations speak of a maintenance interval of one year or according to manufacturer specifications. Compliance with TRGI is a prerequisite if you enter into a gas supply contract. The question of whether this also results in a legal obligation to carry out maintenance for the gas heating system every year is, however, a question that can occupy lawyers for longer.

Questions of liability rarely play a role anyway. Much more frequent in practice are avoidable damage to the heating system and unnecessarily high consumption due to inadequate maintenance. It is therefore in the self-interest of every heating operator to adhere to the manufacturer’s specifications in order to obtain warranty claims and to use the system for a long time and under the best conditions.

Maintenance costs for gas heaters

The average cost of maintaining a gas heating system is between 160 and 200 euros. When the maintenance date for gas heating is approaching, there are no serious differences between the small 15 kW boiler and a heating system with 50 kW output in a two-family or apartment building. The routine work steps are the same and the effort is therefore almost identical. The maintenance costs of floor heating systems in apartment buildings can be lower.

Depending on the agreement, tenants or owners pay for the maintenance of the gas heating in the rental relationship. A maintenance contract makes it easier for you to find an annual appointment and gives you price security. Often the conclusion of such a contract is also the prerequisite to be able to make use of extended warranty services.

Smoke detector / wireless smoke detector

The installation of smoke alarms for the housing industry and private owners is one of our core competences, which we have been exercising since the company was founded. Since 2013, we have also been training certified specialists for smoke alarms in accordance with DIN 14676 and the recommendations of the Forum Brandrauch Prävention e.V. (Fire Smoke Prevention Forum).

With us you receive quality smoke detectors of different manufacturers. Our specialists will be happy to come to your home for a consultation or to make you an offer based on your information. This service will be invoiced to you, if an order is placed, the on-site consultation will be charged against the order.

A burning foam cushion is enough to fill a 3-room apartment completely with toxic smoke.

Smoke alarm obligation

The installation of smoke alarms, also in apartments, is obligatory in almost all federal states. A sensible legislation that saves lives, because we are usually poisoned by smoke gases while we sleep.

Installation and maintenance

Smoke alarms must be installed in accordance with DIN 14676 and serviced annually. The device can only give an early warning if it is installed in the right place and functions properly. The Forum Brandrauchprävention e.V. recommends the project planning, installation and maintenance by a
certified specialist for smoke alarms.

Take your responsibility and make an appointment today with one of our smoke detector experts directly at your home for a non-binding consultation.

So that you can sleep safely

If smoke comes into the measuring chamber of a detector, this triggers an alarm, which is also perceived during sleep. You gain valuable time to effectively extinguish a fire with a fire extinguisher spray or extinguisher. Live and sleep safely.
