XPak® High Efficiency Wall Hung Hydronic Boilers

Raypak's new XPak wall hung boilers bring proven technology to the residential market in a seamlessly smooth product only offered by Raypak.
The XPak is as good for you as it is for the environment. The non-polluting burner is one of the few residential designs that is based on successful commercial boilers that can operate without the necessity of replaceable air filters.
A burner that will not clog with dust and airborne particulates during normal operation is inherently more reliable and trouble free than any other design.
