Always a possibility but generally there are a few storage heaters installed this would be a possible diagnosis if none of the heaters appeared not to be working.
yes this is correct but reliying on a tenants details is not always reliable .....as i found out when i went out to a call out when there imersion was not working ....i asked i they had messed around with anythink ....they replyed no .......but the problem was they had switched the eco7 cu off because they wasent useing the heaters dooh
