The PRO-04-WPL includes controls from Honeywell, an industry leader. Peerless is serious about reliability, and it really shows in the PRO Series. A front-facing access door makes it easy to service a PRO Series boiler and keep it running at peak efficiency levels. Whether you are replacing an older oil boiler or beginning new construction in an area without gas, Peerless's PRO Series is a well-rounded heating solution.
Three Pass Design
The PRO-04-WPL is a three-pass boiler. Three-pass boilers reroute heated gases so that they pass over your heating medium three times, providing additional heat without increasing energy costs.
PRO Series boilers use an insulating and enameled steel jacket to further improve heat retention. By limiting heat loss, the PRO-04-WPL will need less energy to keep you comfortable.
This boiler does not include a burner or damper. Please contact an eComfort.com customer service representative if you require either for your application.
