ONLY Certified HVAC Installers - Read Warranty Policy Before Purchasing
If your home is one of the over two million American homes equipped with an atmospheric (chimney vented) gas boiler, you may already have the basis for a new high efficiency venting system that allows you to take full advantage of the ES2’s chimney venting capabilities. For most homes, it’s as simple as installing a metallic chimney liner that insulates the interior of your chimney. Discuss your particular chimney requirements with your installing contractor.
