Domestic Hot Water Solutions for Hotels and More




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.

How Heat-Timer® Controls Can Make Your Building Management System Better

A  Building Management System  (BMS), also called Building Automation System (BAS) is a system that allows building managers to monitor and control a building’s major mechanical and safety systems in one central, easy-to-use application. A BMS can be thought of as a distributed network of building systems supervised and controlled in one central platform. The network of field controllers and other system controllers are distributed throughout the building and communicate to the BMS through a local area network. Field controllers can be general purpose, supplied by the BMS integrator and used for simple applications like lighting control, ventilation fans and building access. With a BMS, these applications can also be separated by zone, floor or other combinations to yield optimal HVAC performance. Field controllers for mission critical systems like fire alarms and heating are specialized and can act independently, as well as under BMS control. The Heat-Timer® Platinum series boil

  One of the most appealing parts of the Heat-Timer® Platinum Series is the wireless sensor connectivity that comes with our Building Net internet upgrade. There are thousands of clients who own an original, non-internet capable Platinum Series control and when they upgrade the control with our Building Net internet package they actually get two major elements: An Internet/Mobile ready control – The Building Net upgrade gives any platinum control the ability to be controlled via the internet through a simple browser connection to a web management portal, or via our free mobile app. In either case, reports, alarms, control settings, and real-time monitoring are all at your fingertips, wherever those fingertips may be. Wireless Sensor Integration – You can think of this as the second network access that is enabled by the Building Net upgrade. This internal Long Range network allows you to connect our wireless space sensors to the control, which by reporting temperatures in various

Heat-Timer® ETV/ETS – Now Saving Time as well as Money..

Image
  For plumbing professionals, time IS money.  The longer a job takes, the longer your guys are tied up and can’t get to the next job. Or you have to bid the expected time so high that you never get the job in the first place. Heat-Timer® has been helping commercial plumbers for decades by providing them high quality solutions for domestic hot water systems. The most current evolution of our 3-way mixing valve, we call our ETV or Electronic Tempering Valve . This motorized mixing valve is driven by a control module that utilizes an immersion sensor to control the mix of hot and cold water to maintain a desired mixed outlet temp +/- 2 degrees. With our computer guided ETV running the show, you can keep your hot water supply heated hot enough to be safe from bacteria (See Table Below) like Legionella, while delivering a perfectly controlled hot water temperature to end users.  Heat-Timer’s ETV Now Delivered Inside the ETS The Heat-Timer Electronic Tempering Valve (E
