Ravenheat RSF 820/20

Hi I have just seen this review and think its rubish I have an RSF820/20 which is 22 years old over the years I have had a few problems they have been great and when the gas board suggested changing the boiler ravenheat said if its not broken to stay with it. I don't have an opinion on the product as it does what it is meant to but I take exception to a review written by somebody saying they are not helpful

I bought a ravenheat 820/20 to replace a back boiler 13 years ago and since it cost me nothing (unbeleivable but true)to run it.
