I have bought 4 of these pumps. The first had two HP ratings. in a list. Came back for the right horsepower. Installed for my radiant heater. Run for about a week and stopped running. No guarantee, pulled out and ordered new. Got a new one that broke in transit. Revain quickly sent a replacement overnight. Installed a new one. Took the first one apart to fix it. The impeller has ignited. Internet search (try it, it's a European company joke) for parts, dead end. Calls to parts dealers are sold out. I wouldn't give them a star but the lowest is one. A $10 part to fix a $300 pump, and they don't sell this part. Save yourself the heartache, don't buy Grundfos.
