We purchased our heaters in August of this year so for first few months did not have to use them due to the weather but from mid October we have had them on and I have to say our home is so much warmer we are delighted with our new heaters. We purchased the water heater which is also wonderful and due to having this fitted we have gained an extra cupboard for storage. We are all round happy with this product and to add to our delight we have been informed by our utility company that we have used less electricity in the last three months compared to the last three months this time last year and yet our home is so much warmer!!!!! We are all round winners!!
