 In college campus’ or apartment complexes, multiple boilers, multiple boiler rooms and multiple buildings present a real challenge for a complex manager. The tactics employed to keep energy usage at a comfortable minimum are complex and every campus is different, but here are a few of the common issues and solutions faced by these large, distributed, and often older buildings.
Thermal Shock Thermal shock occurs when water cools down significantly during off times, shocking the boilers with cold water when the system pumps come back on line. Not only does this issue damage the boilers, it can also run the maintenance staff ragged as they fly around the building at all hours of the day and night manually adjusting valves. Heat-Timer® products helped resolve these problems by providing motorized valves and Hot Water Reset (HWR) controls in each of the boiler plants. The Platinum Series HWR control helped resolve the boiler problems by operating the system based on outdoor air temperature, as opposed to an indoor thermostat reading. This greatly reduced the excessive on/off action of the pumps and saved our client so much in fuel and boiler maintenance that the controls paid for themselves through energy and maintenance savings, in the first months of usage. Internet and Mobile Alerts and Control While many campus’ are running some kind of remote connection capability, in some cases a master control room visit is still necessary to visually access information on all boiler rooms and buildings. The state of the art at Heat-Timer® in 2019 has moved way beyond this. Our Building-Net system integrates sensor, valve and boiler control, then provides complete visibility to you through our user friendly mobile app, the internet, or your iPad. Our system provides you instant wireless control of temperature settings while sensor data, diagnostics and alerts can be sent, viewed and changed in real-time. With Heat-Timer® sophisticated self-learning controls, diagnostic routines run constantly and detect issues before they cause damage, reporting conveniently to you on your mobile device. Furthermore our newest systems allow real time access to up to 13 months of historical data, reports can be selected or customized, and emailed to you at a convenient frequency. Heat-Timer® Controls are the Right Partner for HVAC Professionals. If you’re going to spend the time to install and learn a commercial heating control that will address the maximum number and type of commercial jobs, you will never go wrong with Heat-Timer®. From motorized valves, to Steam and Hot Water Heating controls, and Domestic Hot Water Boiler Control solutions, we have the controls to support your best work.

 For hotels, motels, office buildings and other buildings with large hot water demand, domestic hot water systems must deliver water that is always bacteria free, and at the right temperature, even during peak periods. Additionally, increased environmental awareness and sound economics is driving the need for more efficient and durable domestic hot water heating solutions than in the past.
Part of the solution to a better DHW system is certainly the boiler. Traditional direct-fired storage water heaters can have efficiency ratings in the low 60% range as compared to 90% or more for modern condensing boilers. Depending on where they are, these heaters can last less than 5 years due to hard water mineral build-up, adding another burden to our landfill and recycling capabilities. Creating a Domestic Hot Water System for the 21st Century It may go without saying but we’ll say it anyway: when designing a commercial DHW system you first want to contact a commercial HVAC professional with good experience. Unlike residential the solution to DHW especially in older buildings, is way beyond the talented handyman. A good HVAC company will provide a design which takes some important principles into account: Reliability. This is probably the most important consideration for commercial domestic hot water solutions. When the system fails to perform adequately or breaks down repeatedly, the entire building is without hot water and residents/occupants are upset. Reliability is achieved by specifying proven high-quality products and by building redundancy into the design. Efficiency. Operating cost and efficiency (EFUE) are important and have much to do with the design of the boilers, and the control systems that regulate the hot water mixing valves and other motorized valves that may be part of your system design. Longevity and serviceability. A well designed system should have a 15–20 year service life. The system design should take into account future service, maintenance and component replacement. Mechanical components should be accessible. Valves should be installed so that pumps and control valves can be replaced without draining down the entire system. Heat-Timer Solutions for Commercial Domestic Hot Water When looking at domestic hot water solutions your mixing valve and its associated control and monitoring system should be a key part of your design. No one wants a solution that has people running to the mechanical room with wrench in hand because the guy in 14B has no hot water! The Heat-Timer® tempering station is rapidly becoming the solution of choice for DHW applications requiring 3 way mixing. It encapsulates an electronic tempering valve under control of dedicated control module. The entire unit is pre-plumbed for professionals. Just connect the hot and cold water to it and plug it in. The control and valve operate together to quickly restore the desired water temperature, even after large changes in load conditions. The ETS is a great solution for challenging DHW applications being both cost effective, and saving installers a massive amount of time.

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.
Valve Types 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 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 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.

The hotel guest stuck with a cold shower will almost certainly give that hotel the cold shoulder next time they go to book a stay. They must provide hot water to all rooms and areas in all locations while ensuring that excessive boiler duty cycles do not run up heating bills. Key to the operation of these systems are the valves that control the mixing and flow of hot water, and the systems that monitor and control these valves. When properly specified and installed, these domestic hot water systems provide perfect on demand control over hot water distribution throughout your resort, hotel or multi-family building at a constant, set temperature while optimizing energy costs.
