The BioSARi product seems to heat the room as designed. I will try and calculate the savings suggested against a traditional heater. I'm a little disappointed with the appearance as the Mable isn't shiny so it's not suitable as a showpiece. You can see the watermarks after the product has been in use for over 4 hours. Ideal for a garage heater or spare room. I would have preferred the controls at the top, so aiding the elderly or a remote option. Registering the warranty process has been difficult, as the order number has is required is not the original customer order number, 5 emails later the support services from the UK managed to assist with this issue.
