At first, Eugene Bourdon was annoyed when he saw what his worker had done to the metal tube. The tube was in the shape of a spiral and it was to go into a laundry machine they were building in Bourdon’s shop.

Have you noticed the strong interest in cold-climate air-source heat pumps over the last couple of years?

The additions include forged bronze vent elbows, a wrot copper extended elbow and a wrot copper fin tube stiffener. All of the products are lead free.

The lower pressure drop on the water side contributes to the compact size and the lower pressure on the flue gas side contributes to the longer approved vent lengths (up to 481’).

An installer sets up a zoned distribution system as shown below. To keep it simple, he uses the same size piping for the headers and all the distribution circuits. The heat source is a low-mass, copper-tube boiler with high-flow resistance.

The schematic in Figure 1 represents a drawing I recently reviewed for a proposed system that was to supply three zones of finned-tube based, two zones of low-temperature radiant panel heating, and an indirect domestic water heater.

Weil-McLain’s Stainless Steel Vertical Firetube (SVF) boiler features industry-leading thermal efficiency up to 97.1%, easy installation and maintenance, the intuitive and user-friendly Unity control system, and Weil-McLain boiler design reliability and longevity.

Salus’ patented Auto Balancing Actuator is specifically designed to balance the flow of water through the underfloor heating system.
