Manifolds vs. Probes Battle w/ Adolfo Wurts (Podcast)

In this episode, Adolfo Wurts from Arbiter comes on and debates why a tech would want to use a manifold over wireless probes and vice versa.

In our industry, we are likely to see a trend of moving towards wireless equipment that connects to a single device. Wireless connections and digital displays may save us money on tools and allow us to store and interpret data more efficiently. However, a manifold can help you recover refrigerant, whereas probes cannot. Manifolds also have sight glasses, which help you check for overfeeding; probes do not offer you much help on that front. Manifolds can also fit into tight spaces a bit more easily than probes, but probes have already come a long way and will continue to get better.

Manifolds may feel heavier and seem more durable, but wireless probes are actually light yet hardy, and you don't have to worry about cracking screens. Probes and manifolds are probably similarly hardy, but probes are lighter and have fewer components to damage. Probes also have a massive edge over manifolds in the area of contamination prevention.

Using your phone with probes has its advantages and disadvantages. Unfortunately, you expose your phone to situations that may damage it. However, you can access all of your readings in real-time from the phone. Your phone also has more processing power, and some apps can perform advanced calculations. You can avoid exposing your personal phone to field damage by using an older, cheaper phone just for field usage.

So, as our society and industry become more tech-savvy, probes will continue to improve. Probes that have an edge now will still improve, and you may want to consider using probes over manifolds. However, you may want to have additional hoses and a sight glass.

HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

In today’s podcast, Bryan talks with legendary Hydronics author and trainer Dan Holohan about the history of steam heating and some practical applications of old ideas. Recently, Dan has been working on more novels, having published two of them over the past few months.

Steam heating is a “lost art” nowadays; it has become increasingly uncommon and has been disappearing since the Vietnam War. Many people who understood steam heating either retired or died after the Vietnam War. Many elements of steam heating are difficult to understand or surprising. (For example, steam pressure has a surprising relationship with velocity: low-pressure steam moves through piping much more quickly than high-pressure steam.) So, Dan Holohan is on a mission to revive that knowledge and teach the newer generations about the lost art.

There are many older steam heating systems still operating today, especially in the older large buildings in New York. Dan learned a lot about steam heating when working on these old systems and optimizing them. Most of the time, he optimized those systems by removing unnecessary accessories, not by adding components like steam traps.

Many old boilers used coal as a heat source. Nowadays, many old boilers have been fitted with conversion oil burners with thermostats, but they are still piped for coal. Some systems now have multiple risers or massive vents on the main riser to prevent the thermostats from getting too hot too early and satisfying the thermostat too early. We call that master venting, which reduces pressure and allows steam to move very quickly and efficiently.

Dan also discusses:

The 2-PSI standard
Transportation metaphors for BTUs in steam
Harmful renovations for old boilers
Replacement vs. restoration mindsets
Gaps in steam boiler education
Monopolizing the market if you HAVE the education
Boiler piping and venting
Two-pipe vs one-pipe steam
