Electric Boiler Ratings, A Repairman Rates The Brands...

We have given each brand a rating of from 1 to 5 stars. A 5* rating means that, if we were shopping for a unit for our own home, that is the brand we would choose. When more than one brand has a 5* rating, we would choose the least expensive model if it was available.

For your convenience, we have included the manufacturers' web addresses as well as our comments regarding their products.
