no hot water

[billybut]

hi i have just moved into a 12 year old bungalow this has oil fired heating and hot water (not a combi boiler ) all was ok untill i had a shower this is gravity fed and not much use (dont think its been used for years ) i think since using it i now cannot get any hot water at all. Central heating ok and light comes on for hot water on the programmer but water not getting hot is it possible it is air locked or something similar aqny help would be appreciated thanks.Trev:disappointed:

could be your storage cistern is too small and your shower time too long, causing an airlock, best get an expert to advice after having a look
