I installed Herschel California 2KW infrared Heaters in my walled patio area before the summer. They are not only very high quality as a product but create an exceptional heat output that feels exactly like sitting in the sun on a warm day. Even in the middle of winter they can make your outside area fully usable. I would really recommend these and Herschel products in general for anyone that is looking for high quality, excellent function coupled with top class aesthetics and product design.
