everyone, I am looking for some advice regarding my standing-pilot gas boiler setup and excessive standby gas usage. Boiler Details: Make & Model: Viessmann Chaudière Gaz INOX 24 (Type EF 24) Year of Manufacture: 1989 Serial / Fab No.: 7088414 Burner Assembly No.: 7088344 Issue: My boiler appears to be consuming around 7 kWh of gas daily solely in pilot/standby mode with no active heating load. Questions: Can anyone confirm if part #7812877 (Viessmann pilot burner assembly) is the correct factory replacement part for this INOX 24 model? Will replacing the pilot assembly help reduce this daily standby gas usage, or is a ~7 kWh daily loss standard for this vintage due to flue draft / thermal radiation losses? Are there any recommended adjustments to the pilot injector/gas valve or retrofits to cut down on this standby consumption? Any insights or recommendations from experienced technicians would be greatly appreciated! Hello everyone, I need advice regarding my gas boiler with a constant pilot light and excessive standby gas consumption. Device data : Manufacturer & Model: Viessmann Chaudière Gaz INOX 24 (Type EF 24) Year of construction : 1989 Manufacturing number / production number: 7088414 Burner assembly no.: 7088344 Problem: My boiler apparently consumes around 7 kWh of gas per day just for the pilot light or in standby mode, without any heating or hot water requirements. Questions : Can anyone confirm if part number #7812877 (Viessmann ignition burner assembly) is the correct replacement part for this INOX 24 model? Will replacing the pilot burner assembly help reduce this daily standby gas consumption, or is a daily loss of ~7 kWh normal for a building of this age due to buoyancy and heat losses? Are there any recommendations for adjusting the ignition nozzle/gas valve or retrofit options to reduce this standby consumption? I would be very grateful for tips and advice from experienced heating engineers or technicians!
