Most of the 5-star reviews are new installations. I would have given ours 5 stars after 2 years. We had a slow leak in the system that got worse over the last 5 years. Engineer finally found the Combination Stainless Steel secondary heat exchanger had a crack on the weld. 7 years and a major component fail. Never mind all the poorly designed washers failing too! Warmflow blamed the expansion tank which has been checked EVERY year during servicing. Our local engineer was offended by their comments. Don’t waste your money……. BTW they did NOT honor the 10 year warrenty.
