If the flow temperature increases too quickly in heating mode on your Baxi Boiler, it may be due to insufficient circulation or other causes. You should: * Check the boiler/installation circulation. * Activate a manual venting cycle. * Check the installation pressure. * Check the operation of the pump. * Check the cleanliness of the exchanger. * Check the operation and connection of the temperature sensors.
