Typical models offer efficiencies around 90%, which brings most brands of condensing gas boiler in to the highest available categories for energy efficiency.

Guide to Managing the Condensate for Condensing

The condensing process is achieved by passing the piped hot flue gases through the cooler return water flowing back into the boiler. Flue gas starts to condense when it drops below its dew point of 55°C. This is why condensing boilers are designed to accommodate a return water temperature of 54°C or less.

A typical example is the draining of condensate from steam traps installed on main utility steam lines.

Reasons why the condensate- or boiler-feed pump is

Reasons why the condensate- or boiler-feed pump is misbehaving, and where to look for solutions. If the pump's pressure can't overcome the boiler's pressure, the pump can't return the condensate to the boiler. Lower the boiler pressure (if that makes sense), or increase the head pressure of the condensate pump (by replacing it).
