Annual overhaul, repair of gas installations and repair of boilers and heating circuits.

The package includes an initial diagnosis of your gas installation and heating system (boiler, hydraulic circuit and radiators), an annual service to anticipate possible breakdowns that could increase your energy consumption. OKGas keeps the installation safe, extends equipment life and on average reduces breakdowns by 2/3, thus optimising gas consumption and, with it, the amount of your bill.

Whenever your heater breaks down, you can contact the OKGas technical department and a technician will visit your home in less than 3 hours to repair the breakdown (travel and the first 3 hours labour are free). Customers of OKGas have access to a free telephone number to request assistance, operational 24 hours 365 days a year: 900 85 86 85. Unlimited number of repairs.

OKGas enables you to comply with the regulations in force (R.D. 919/2006) and Thermal Installations in Buildings (R.D. 1027/2007), which by law require a biennial service of gas installations and equipment. In addition, the OKGas includes the cost of the Mandatory Periodic Inspection of the gas installation every 5 years which is obligatory, as long as you have also contracted the gas with Endesa Energía.

Other packages only cover the boiler and not the gas installation, or only cover maintenance and not repairs. OKGas takes care of everything.

OKGas covers the cost of the Mandatory Periodic Inspection valued at approximately €60.

You can pay for OKGas in convenient gas bill instalments and with a 50% discount during the first year.

You have a professional of the Endesa Networkendorsed by rigorous quality controlswho will repair any breakdowns that occur, in addition to flexibility in arranging the visit. Plus, the number of repairs is unlimited.

Any costs of travel and the first 3 hours of labour on each visit are avoided, (parts are to be paid by the Customer, if a repair of the gas installation or boiler-heating equipment, hydraulic circuit or the radiators is necessary). In exceptional circumstances, in which the repair time exceeds 3 hours, we undertake to provide a free prior quotation.

Endesa exhaustively controls the quality criteria as well as the deadlines established for undertaking the work. In addition, random calls are also made regarding the operations carried out as well as satisfaction surveys, in which Customers usually give excellent ratings above 8 points out of 10.

Servicing the installation prevents, mainly, any possible gas leaks which would affect the safety of the inhabitants of the dwelling and, in addition, would mean an increase in energy consumption and the amount of bills.

Such inspections are of a preventive nature to check the condition, safety and correct operation of the gas installation and of the heating equipment (boiler, hydraulic circuit and radiators), in accordance with legal and technical regulations.

The heating circuit is the pipe routing through which the hot water runs from the boiler to each of the radiators. The most common faults occur in: the circulation pump, the safety valve, the circuit pressure, the boiler fumes outlet, the temperature probe that checks whether the water is hot or the radiator taps.

During a technical inspection, the following is carried out:

  • A check of all the installation's components (keys, fasteners, pipes, nozzles, ventilation, etc.).
  • Necessary adjustments to guarantee the safety of the installation and, to the greatest extent possible, reduce the gas consumption, number of breakdowns or future failures of the equipment.
  • Checking for leaks in the gas installation.
  • Checking and adjusting the equipment’s operation.
  • Combustion analysis and submission of the result.
  • Mandatory Periodic Inspection of the gas installation.
  • Mandatory revision of Regulations for thermal installations in buildings (in Spanish, RITE).

The contract lasts for one year and it is automatically extended on an annual basis. However, both the Customer and Endesa may terminate the contract giving written notice of at least one month prior to the expiration date.

The 50% discount (when contracting online) on the package fee has a duration of one year from the start date of the contract.

If you also have a gas supply contract with Endesa Energía, the OKGas package will be invoiced within the gas bill, in the following way monthly or bimonthlyaccording to the billing cycle thereof.
