ThermOmegaTech, Inc has been honored by having two of our valves nominated for Consulting-Specifying Engineer Magazine’s annual Product of the Year award. Both the Circuit Solver™ and the DTV are in the running to be the best Plumbing and Water Management product.
We came across this article on return temperatures. It addresses some key issues in regards to domestic hot water balancing. Our new Circuit Solver™ can be a great way to fix, and even eliminate problems with hot water delivery.
The Importance of Return Temperatures
Delivery & Return Temperatures are the two most critical numbers; these are the temperatures available to the residents at the beginning and at the end of the hot water loop. Too hot is unsafe, too low is unacceptable for cleaning or comfort.
Low Return Temperature is commonly ignored because diagnosis can be tedious and it doesn’t seem like a dangerous problem. Wrong.
Do not ignore a Low Return Temperature Warning! A drop in temperature from delivery to return means that:
- Households are quietly suffering with low water temperature,
- Residents might be scalded by dangerous fluctuations in water temperature, and,
- You are wasting fuel through heat loss.
Return Temperature is like a canary in a coal mine: if there is anything wrong with the hot water system it is often the first alarm to go off. If your return temperature chart isn’t in the pink, your boilers are probably in fine order. But, if you’re seeing a lot of pink, it’s time to fix things before your residents start seeing red

Avoid permanent injury, freeze damage and corrosion.
- Federal regulations require you to flush supply lines to emergency showers and eyewash stations weekly.
- The water passing through these devices must be at a temperature between 60°F and 100°F.
- The showers/eyewashes must be placed strategically, depending on the plant’s physical layout.
Regulations and standards are intended to help keep employees and processes safe. Water temperature can mean the difference between whether an employee incurs permanent injury in an accident, whether outdoor processing facilities avoid expensive freeze damage, and whether a plant can keep operating without extensive maintenance. These matters are critical to operating a safe, compliant and efficient plant. Continue reading
Fred was born on February 17, 1946 in San Antonio, TX to Charles Earl Pirkle and Zutella Bones Pirkle. He lived in San Antonio throughout his childhood and graduated from Harlandale High School in 1964.
In 1970 Fred received a B.S. from the Department of Industrial Technology at Sam Houston State University in Huntsville, TX and in 1972 he received a Masters degree from the same place.
“Shotgun Fred’s Guru Crew” The Walk to Defeat ALS!!!
Fred Pirkle, aka “Shotgun Fred”, founded ThermOmegaTech® in 1982. Since then he has patented more than 20 products, including the first temperature control device for charcoal grills/cookers – hence “The BBQ Guru” was born in 2004.
In April 2011, Fred was diagnosed with ALS. As his friends and family are well aware, he is a fighter and continues to fight the disease every day. In Fred’s honor, and in an effort to help support patient service programs and ALS research, ThermOmegaTech and The BBQ Guru have joined forces with the ALS Association. We are a corporate sponsor of and have formed a team, “Shotgun Fred’s Guru Crew”. On Saturday, November 5th we participated in our first Walk to Defeat ALS.

The International Plumbing Code, 2006, paragraph 701.7 reads, “Wastewater when discharged into the building drainage system shall be at a temperature not higher than 140°F (60°C). When higher temperatures exist, approved cooling methods shall be provided.
Freeze protection valves are effective in preventing freeze damage in process lines. Unlike steam or electric tracing, which require power and can cause water to overheat, freeze protection valves operate by simply draining or bleeding water as the temperature approaches freezing.
This prevents the formation of ice that can clog lines, shut off flow, and cause pressure within the line to build, cracking pipes, valves, and fittings, as well as dam- aging equipment. Damage due to ice formation can incur costs for replacement parts and labor, and reduce productivity due to shutdowns.
Nonetheless, freeze protection valves do not necessarily completely prevent the formation of ice. In some cases, ice may still form as a layer on the inside of a pipe. This actually acts as a good insulator, reducing further heat loss to the cold outside air. Also, if the ice does not completely block the pipe or equipment flow area, no damage will occur. Damage due to freezing is caused when a pipe or flow passage in equipment is completely blocked. Then, as additional ice forms, the expansion associated with the ice formation compresses the water and causes a dramatic increase in the internal pressure in the line. When the pressure exceeds the strength of the pipe or housing, these will break.

Circuit Solver from ThermOmegaTech, Inc.
Circuit Solver is a self-actuating thermostatic recirculation valve which automatically and continuously maintains the end of each domestic hot water supply line at the specified water temperature. This simple inline valve completely eliminates the need for time consuming and expensive manual balancing procedures and equipment. By allowing only water that actually cools below the setpoint to flow to the return, Circuit Solver also eliminates the need for oversized recirculation pumps which cause pipeline erosion and waste energy.
1. Water flows to the path of least resistance.
2. Many buildings require multiple branches off the hot water supply line.
3. Hot water use is hyper-dynamic, so the path of least resistance constantly changes.
4. Manual flow control valves cannot properly resolve these issues.
Install a Circuit Solver Valve on each hot water supply branch line immediately downstream of the last run out to a hot tap.
Australia has the highest average amount of solar radiation of any continent, making it the perfect place for generating power or heating water with energy from the sun. Not surprisingly, the combination of generous rebates and sunny weather has given rise to solar thermal installations across the continent. Generally these installations are quite straightforward, but in the southern part of the continent, temperatures can drop below zero (Celsius), causing freezing problems for some thermal systems.
OSHA Standard 1910.151(c)
Need a refresher on the OSHA standard for safety showers and eyewash stations?
Will OSHA cite a facility for not following the recommendations as stated in ANSI standard Z358.1-1990? Specifically, will an OSHA inspector cite a facility for not supplying tempered water to an emergency eyewash and shower?
