Combi boiler installation and commissioning
Installing a combi boiler is more than hanging a unit on the wall: correct capacity selection, flue and condensate connections, system flushing and commissioning are all part of the job. As an authorised Vaillant dealer we install to warranty requirements.

First we assess the heated area, glazing and insulation levels and your hot water demand to determine the required capacity. For a typical two-bedroom flat in Antalya a 23–24 kW condensing boiler is usually enough, while larger flats and homes with two bathrooms are better served by 29–34 kW models.
Before fitting, the radiator system is flushed and, where needed, a filter and water treatment are added. In condensing boilers the acidic condensate must be routed to a suitable drain and the flue kit must match the appliance; our team never skips these details.
Once the gas, water and electrical connections are complete, the boiler is commissioned. Gas pressure and combustion values are measured, the heating curve and comfort settings are adjusted and the warranty record is completed. Before handover we walk you through how to use the appliance.
