24/7 availability of hot water at the right temperature is a hot button issue for facility managers in the hospitality, education and healthcare industries. To avoid both scalding and bacteria growth, water must be stored at a high temperature, then mixed with just the right amount of cold water before being delivered to the end user. The valves that provide this mixing are the key to reliable and safe, domestic hot water.
There are two types of mixing valves that can properly temper domestic hot water: motorized and thermostatic. Motorized valves use electronic sensors and controls which helps to restore ideal water temperature under peak loads. Thermostatic valves use an internal thermostatic element to control temperature without the need for external power. They both produce a reliable safe supply of domestic hot water. They differ in how they are controlled, and in what features are available to communicate with them remotely.
Motorized valves are meant to interface with electronic controls to precisely dial in the supply temperature. These valves can be provided as stand-alone units, or they can be integrated into the building’s heating control system to provide remote monitoring and control capabilities that allow building operators to monitor and adjust their systems without the need to visit the mechanical room.
An example of a robust motorized valve is our Heat-TimerⓇ motorized 3 way mixing valve for DHW that is controlled electronically by our ETV Platinum Plus Control. Using this combination, installers can easily retrofit underperforming mixing valve implementations with a robustly designed valve/control system combo that yields advanced features:
Thermostatic valves are the trusty workhorses of the domestic water mixing valve world. For hospitals and nursing homes they provide the long term steady performance that is needed. What they lack in communication and remote monitoring capability is made up for in simplicity and reliability. They do not require power since they use an internal thermostatic element to control the output temperature to the set-point set via thermostat. These valves are ideal for locations where long term durability and reliability are key, and remote monitoring is not necessary.

While “green solutions” are often looked at as renewable energy or recycled materials, in the building heating controls industry, this includes solutions that save the customer in overall energy consumption. Less energy used typically means less energy produced which means lower carbon footprint, less pollution from dirty energy sources, etc…
And incidentally, the other meaning of “Green” applies too. Heat-Timer Controls save building operators money, usually big money on yearly heating costs.
The need to maintain heating system efficiency is key creating a green solution. Heat Timer® control systems can offer just that, putting the customer’s mind at ease knowing they’re participating in a green movement, decreasing energy consumption, and extending the life of their boiler and associated subsystems by lowering maintenance and replacement costs.
Why is my Heating System Not Already “Green”?
After a building has been designed and commissioned, there are a number of ways a control system can become inefficient or be forced out of calibration. Many systems even those with newer more efficient boilers, lack the central brain to control and manage a large distributed system, resulting in midnight visits to the boiler room after irate tenant phone calls, just like it was 100 years ago.
Normally, a system will undergo a retro-commissioning or recommissioning effort every 5-10 years. This includes a full building energy audit study of a facility, finding places in the system where inefficiencies have developed over time. This can include: boiler control resets, boiler lockouts, outside air resets, domestic hot water storage leaks, and the list goes on. The point is, this is a lengthy, time consuming and costly endeavor that could easily be avoided through the use of a modern Heating Control system.

In apartment buildings with centralized heating systems, maintaining comfort levels for the entire occupied space can be a frustrating and expensive undertaking. No one likes to be confronted with angry calls from tenants about continued issues with the temperatures in their unit that never seem to go away.
As makers of the worlds most sophisticated heating controls, Heat-Timer® expertise is often consulted when commercial HVAC companies are trying to solve these issues, especially in older buildings. The following is a great example of how tenant comfort can be proactively, and economically managed by a smart implementation of Heat-Timer Control systems.
How to stay ahead of the curve on Heating issues.
General Managers of both small and large apartment complexes face unique heating challenges. Being aware of them before a tenant complains and being able to resolve them quickly before they cost the complex money, has always been the goal of Heat-Timer controls.
Temperature instability in your buildings can be caused by many different issues, and the services of a truly capable commercial HVAC company is essential to analyzing and resolving them. In some cases, we have seen the breakdown and drift of control systems in older buildings forcing building engineers to actually make out complex schedules for manually changing the positions of various steam valves in the complex based on outside temperature. Not only is this a tremendous challenge, but ultimately it is doomed to fail in large installations, as well as wreaking havoc with the quality of life of building engineers and maintenance personnel.
In these cases, temperature variations in parts of the building can be caused by a lack of respect for the ambient outdoor temperature. Because this factor changes frequently and older control systems do not accurately incorporate this into boiler management protocols, you end up with situations where boilers are running too hot, too often. In other cases, boilers encounter “thermal shock” because they’ve been completely shut off for too long. These scenarios not only contribute to excess energy usage but greatly increase the need for boiler maintenance and more frequent, expensive replacement.
One Way to Solve the Heat Distribution Problem
An example solution for one of our clients involved implementation of our Heat-Timer SRC Platinum Steam Outdoor Reset Controls. The SRC regulates the amount of steam based on the current outdoor air temperature. It controls the amount of heat by continuously modulating the packless steam valve. By monitoring the outdoor air temperature, the SRC control can anticipate a heating demand increase or decrease and modulates the valve accordingly. The colder it is outside, the more steam that is allowed to enter the building’s radiation.
But perhaps the best part of implementing the Platinum control was its affect on the quality of life of the building maintenance crew. Heat Timer’s platinum series supports our Internet Control Management System (ICMS) which we call BuildingNet. This Internet Communication package allows you to monitor and adjust any Internet-ready Platinum Series heating control from any Internet browser. All the operating and recording software is contained within the panel. This means the control can be accessed from any computer or mobile device with Internet connection. Alarms are pre-configured to alert building managers before problems occur, allowing problems to be anticipated and solved from the golf course, instead of requiring a midnight visit to the boiler room.
Heat-Timer Wants to Solve your Energy Consumption Problem
The cost of upgrading to Heat-Timer Controls is generally dwarfed by the savings in fuel in the first month of operation for a large complex.
“The reduced boiler maintenance after the installation of the (Platinum Series) HWRs was enough to pay for the controls.” James Marsanico, General Manager
