4 high really good heater very good do not use a plastic part of the bracket inside cane loose and landed on the element whilst all my family were asleep this caused a small fire in the unit and covered the flat in plastic smoke lucky enough we have fire alarms and they were set off to wake my wife

My study is about 2

Clearly a design fault left with a faulty unit and a flat that smells of burnt plastic easy to carry backup heating for our two living rooms

I bought it to heat a wooden garden room it heats really quickly and the room stays warm
