At your request, your central heating boiler will be serviced or repaired in the event of malfunctions. The costs are invoiced on the basis of actual costing, but you do pay call-out costs. These depend on your place of residence.
Your central heating boiler receives annual maintenance. You then pay an agreed price and you can contact us 365 days a year for malfunctions. (calculated on the basis of subsequent calculation, without call-out costs!)
