Easy to install and seams really solid. Looks easy to change the element if it ever fails in the future or change it to a different size if I missed on my calculations. Has been running my workshop heat for a week now and seems to be really efficient.
I had very prompt service. This pump is beautifully made, and runs silently with minimal vibration. It has snap electrical connections and avoids use of those troublesome twist connectors. This pump is strongly recommended and is at the front of the pack. There is no doubt about that.
