I bought this Delonghi dragon 4 heater for our daughter, her unit is brick and cold. Much better than the reverse cycle , heat radiates lower around the room. Takes a while to heat up, but is cosy. Safe, but does become hot on the outside of the unit. Care needs to be taken with children Incase they touch the outside of heater. So far, it’s been a success. Was a little disappointed , as there were two small dints on the outer end columns, maybe done in transit,as had come in a truck from NSW. So far it hasn’t impaired the operation of the heater.
