On October 15, 2015 I experienced a leaking furnace. The diagnosis turned out to be an issue with the external hot water tank, HTP Superstor Ultra, which was under a lifetime warrantee. The process was to first purchase a new water heater, return the faulty one and the manufacturer would refund the cost of purchase, which they returned to the wholesaler, Emerson Swan 1-800-346-9215, who in turn seems to have issued a credit to R.H. Ordway Heating & Air Conditioning instead of returning the funds to me. The plumber freely admitted to having received the credit, but has never returned the funds in the amount of $1330.25 to me.
