Immersion tank - boost option on hortsmann economy 7 - Central Heating job in Hornsey, North London

Job description


I am having issues with my immersion tank linked to a Hortsmann Economy 7 box. The Economy 7 boost button no longer seems to provide hot water. Although the boost button still lights up, you no longer get a hissing sound in the tank to suggest it is heating up.

Off-peak still works fine overnight and from this i'm able to get enough hot water for one bath.

Not sure if an element in the top tank needs replaced?

Are you able to help with this?
