just moved into this house which has a british gas 330 heating system. no instruction manual and want to know how to increase the temperature of the hot water. hope you can help.
Without sarcasm, press top dimpled part of front cover, water temp from boiler is adjusted there (+/-). Also, there should be a thermostat on your hot water tank ('stuck' or tied to the tank) that sets the tepmerature of the water in the tank (at least 50 deg. needed). The maximum this can be set to is the same as the boiler. Hope this helps.
