Combining a wood-fired boiler with a hydronic distribution system

Doing wood right

March 27, 2024

I’ve written many PM columns discussing how air-to-water and geothermal water-to-water heat pumps can be combined with hydronic delivery systems to deliver efficiency AND superior comfort. This combination is a great solution for many consumers.

PM's John Siegenthaler releases HydroSketch software for hydronic system design

HydroSketch is designed for those who have little or no previous experience with computer drawing soft-ware

October 19, 2018

HydroSketch also allows users to create their own custom component symbols, and take advantage of expanded drawing libraries.

An installer who is used to boiler replacements may view the mechanical room aspects of changing from a boiler to a geothermal heat pump the same as a boiler changeout; just swapping out one “box” for another. Unfortunately, this can lead to some significant operating problems.
