First heater 3kw cathalitic fails to start. We really struggled with it for 45min and nothing. It was impossible to get it going. Ordered right away another model for my grandma. The Camilla 4.3kWh which is fab. Real warm and so easy to start but arrived dented up by DPD who tossed it over a 6ft gate. I have called again and now waiting for the 3kwh model this last whole week to be pick-up by DPD. I hope this gets resolved soon. I will not be paying anything more. I have called 3 times and explained it to 2 different people. I do not want two heaters...just one that actually works and is easy to start up by a 88 year old. I am happy with the Camilla 4.3kwh model..but the other one I do not recommend, very difficult to light up.
