We have a Gledhill Waters boilermate and our central heating and hot water have stopped. The gas is metered and ran out yesturday, we put money on the meter and the gas is back on (oven works fine) but the C/H and H/W is not back on. Im pressuming its something to do with the pilot light but have no idea how the system works and is nothing like systems i have previously seen. Any ideas??!!
