The Glitch & The Fix

RSS

Eager to keep up with new technology, an installer decides to install a hydraulic separator between a boiler and distribution system.

To say this system is a piping aberration is going easy on it.

An installer is asked to provide a system that supplies two zones of fin-tube baseboard and two zones of floor heating.

When floor heating and domestic water heating occurred at the same time, I discovered there was no flow through the heat exchanger in the indirect tank.

The cardinal rule of multiple boiler systems is to only provide flow through a boiler that’s operating.

At one point in time, this schematic appeared in a manufacturer's installation manual.

An installer was asked by a client to use both a ground source heat pump and a boiler as alternative heat sources in a zoned, low-temperature hydronic distribution system.

An installer decides to replace a 30-year-old cast-iron boiler with a modern mod/con unit.

An installer uses a 4-way motorized mixing valve to interface between a conventional gas-fired cast-iron boiler and a low temperature radiant panel system.

A project requires both medium and low temperature radiant floor panels. The installer proposes the following system design.
