We had a Waterford Erin for about 9 years and it was great. We mostly used turf and in the very cold weather we used some coal. About an hour and a half after lighting it, it would heat 6 to 7 rads. We filled the fire completely and found this was the best way to use it. We normally did not fill it after 10.30 approx. We had hot water also. We changed to an oil stove last year and sold the Erin. We got tired of the ashes and the turf but I really miss it as it was much better and cheaper than the oil.
