“Thank you very much for installing the cowl on my chimney. I have now been using the woodburner with the cowl fitted for about 3 months. 1 The fire lights and draws much quicker than previously, particularly on cold windless days. 2 I used to use coal as a base in order to get a hotter fire and draw but now find this unnecessary. 3 The woodburner seems to burn hotter and appears to burn longer for the same amount of wood. A small but financial miracle! I must say we are both delighted with cowl and it does not look unsightly or out of place on our period property chimney stack. Thank you very much for the cowl and I wish you success with your product” Kind regards”
