Why does my Intergas Combi Compact HRE 24/18 Boiler burner ignite noisily?
- S
  Sheena PooleAug 25, 2025
  If your Intergas Boiler's burner ignites noisily, it could be due to several reasons: * The gas supply pressure might be too high. The house pressure switch may be faulty; contact the gas company. * The ignition electrode gap may be incorrect; check the ignition electrode gap. * The gas/air adjustment may not be correctly set; check the setting (refer to gas/air adjustment guidelines). * There might be a weak spark; the spark gap should be approximately 4.5 mm.

Why is my Intergas Boiler not producing hot water (DHW)?
- R
  Rachel SmithAug 26, 2025
  If your Intergas Boiler is not providing hot water, consider the following: * Replace the flow switch if the DHW flow is less than 2.0 l/min. * Check the wiring according to the diagram if there's no current at the flow switch (5V DC). * Replace S3 if the burner isn't firing on DHW. * Refer to the 'burner does not ignite' section if the burner isn't igniting.

Why is the burner resonating in my Intergas Combi Compact HRE 24/18 Boiler?
- C
  Cheryl SmithAug 27, 2025
  If your Intergas Boiler's burner is resonating, consider these potential causes: * The gas supply pressure may be too low. The house pressure switch may be faulty; contact the gas company. * There might be recirculation of combustion gasses; check the gas flue and the air supply. * The gas/air adjustment might not be correctly set; check the setting (refer to gas/air adjustment guidelines).

Why does the hot water from my Intergas Combi Compact HRE 24/18 not reach temperature?
- S
  Sara GrantAug 29, 2025
  If your Intergas Boiler's hot water isn't reaching the desired temperature, consider the following: * Adjust the inlet assembly if the DHW flow is too high. * Set the hot water circuit depending on the desired temperature, if the temperature setting for the water circuit is too low. * Descale or flush the exchanger DHW side if there's no heat transfer due to lime scale or fouling in the heat exchanger DHW side.

Why is my Intergas Boiler's CH not reaching the set temperature?
- C
  christopher54Aug 31, 2025
  If the central heating (CH) in your Intergas Boiler isn't reaching the set temperature, consider these steps: * Check and adjust the room thermostat setting to 0.1A if it's incorrect. * Increase the CH temperature if it's too low. Check the outside sensor for short circuiting and rectify if needed. * Increase the pump setting or replace the pump if it's not running correctly or the setting is too low. * Ensure there is circulation in the installation; at least 2 or 3 radiators must be open. * Adjust the power if the boiler power hasn't been correctly set for the installation (refer to setting maximum CH power). * De-scale or flush the heat exchanger on the CH side if there's no heat transfer due to lime scale or fouling.
