Ask a heating pro about the energy used by the systems they design or install.

One of the benefits of modern hydronic heating is the ability to use multiple types of heat emitters in the same system. 

We are proud to present this fifth and final edition in the "Siggy" eBook series specifically for the hydronics market. Brought to you by Plumbing & Mechanical, PM Engineer and Supply House Times, this FREE eBook is a collection of columns and articles from John Siegenthaler, P.E., a well-respected hydronics expert.

This was quite a year for me on the home front. On fairly short notice, my wife and I found out that our daughter Heidi and her husband Andy would be building a house about 500 feet down the road from us. 

An installer is asked to connect an old (but still working) propane-fueled cast-iron boiler, which was salvaged from another project, to a slab-on-grade floor heating system in a new workshop.

Some renewable energy heat sources require large thermal storage tanks. Examples include systems’ biomass boilers and solar thermal collectors.

Because they generate heat intermittently, renewable energy heat sources such as solar thermal collectors and pellet boilers require thermal storage tanks. So do storage-based systems using off-peak electricity, or micro combined heat and power (MCHP) generation.

When water is heated, the space required for each molecule increases. Any attempt to prevent this expansion will be met by tremendous forces.

An installer was asked to include an air-to-water heat pump into a low-temperature radiant panel heating system supplied by a mod/con boiler.
