Why choose eb4?
If a chimney is not available, or if oil or gas isn't practical, the eb4 is an excellent way to provide hydronic or radiant heat.
The eb4 fits in a very small space. With all its components "under cover", it has a finished look.
The eb4 is easy to install, service and use. The circulator and pressure temperature gauge are installed and wired at the factory to simplify installation. W9ith its simple delay controls for start-up and run functions, operation is smooth and quiet.
The eb4 is especially suited for hydronic heating. Lower temperatures are possible because the system is not used to heat domestic hot water.
