THE PHOENIX EVOLUTION COMBINED HYDRONIC APPLIANCE melds space heating and domestic hot water in a 96% efficient package. It consists of a storage tank, available in 55-, 80- or 119-gal. sizes; a modulating burner assembly attached to the outside bottom of the tank; and a space-heating module containing a heat exchanger and a variable speed pump. The installer does not have to bother with a primary/secondary loop, near-boiler piping or isolation valves. The 55-gal. model is just 34" X 53".
