John Siegenthaler: Modifying high-temperature distribution systems for lower-temperature operation — part two

Part two of a series
Siegenthaler
John Siegenthaler P.E.
January 3, 2023
One Comment

As with most things hydronic, there are multiple approaches, and the “best” approach for each installation has to consider cost, aesthetics, access to the existing piping, available wall space and the goal of how the overall system will operate based on existing or newly created zones.

flexible nature of PEX means the pipe can bend

How to design and size PEX pipe the right way

Best practices for designing and installing PEX to leverage the benefits of installation efficiencies, job-site safety and profitability potential.
December 22, 2022
One Comment

Most plumbing professionals in residential construction know PEX. They have either used it themselves or know other designers or installers that are using it. That’s because PEX is the piping product used in more new-home construction than copper and CPVC combined.

John Siegenthaler: DHW Trifecta

Coordinated ways to add heat to domestic water.
Siegenthaler
John Siegenthaler P.E.
November 2, 2022
No Comments

One of the best things about hydronic heating systems is that it’s easy to integrate some method of domestic water heating. This combination has been used for decades in systems where a boiler was the sole heat source. It’s also possible when a heat pump serves as the heat source.

John Siegenthaler: Hydraulic energy conservation

Don’t be wasteful.

John Siegenthaler P.E.
October 3, 2022
No Comments

John Siegenthaler: How to add a pellet boiler to a forced-air heating system

Pellets to plenums
Siegenthaler
John Siegenthaler P.E.
August 31, 2022
One Comment

I’ve covered pellet-fueled boiler applications in several past issues of PME. All of them have involved hydronic distribution systems. While such applications are certainly the prevailing way pellet boilers are used, they are not the only option. It’s possible to couple a pellet boiler to a forced air distribution system.
