how do I increase the pressure on my boiler?

Ed Willson, December 2012

depending on the boiler, there should be a filling loop (usually a silver flexible tube with a control knob each end. if not directly under the boiler itself there should be a tap, turn on taps and wait untill arrow on gague reaches 1.5 bar (middle of green section)
