The addition of 4-in-1 Low Loss Header (LLH) accessory closes the gap to provide a fully contained boiler system

Bosch Thermotechnology, a leading global source of high-quality heating and cooling systems, today announced its Stainless Steel Boiler (SSB) Low Loss Header (LLH) accessory, completing its SSB System for a fully contained, compact boiler solution.

The Bosch SSB LLH 4-in-1 combination separator incorporates hydraulic separation, air separation, dirt separation and ferrous impurity separation. The dirt and magnetic separator helps to ensure clean water circulation through the boiler loop. With one hot water supply and one water return, every connection is only used once. Temperature is not an issue with this system, which is ideal for temperatures from 32 – 194˚F without insulation.

“We’re thrilled to be the first in the market to provide four-in-one performance functionality for a fully contained boiler system,” said Christopher Kyes, Product Manager at Bosch Thermotechnology. “This full system provides simple installation and maintenance, whether in a new build or retrofitting to an existing building, offering a high efficiency boiler solution.”

The Bosch SSB Low Loss Header features include:

  • Hydraulic separation, air separation, dirt separation, and ferrous impurity separation
  • Suitable for water and glycol solutions
  • Max Pressure range 80 PSI
  • Pipes can be fitted on either side of the boiler
  • Integrated 75PSI pressure relief valves
  • 5-year non-prorated heat exchanger warranty

The SSB System was engineered by Bosch on a single platform design, making installation and commissioning easy, regardless of the output required. With an efficiency of 96 percent, the SSB is loaded with standard features that include dedicated boiler pumps, two heat exchangers and on-board control with weather compensation, practical control solutions for any application and several venting options, as well as many other features.

With the new normal brought about by the global pandemic, high-performance building is now focusing on the safety of occupants. This is especially true for healthcare buildings. So now, in addition to ensuring the systems you design and install not only perform reliably and meet project schedules and budgets, you also must ensure they can support a superior indoor environment. How can contractors meet these new demands while also staying efficient and profitable in every project? Start by looking at the piping materials.

A domestic water system has the responsibility of bringing water from the main source and distributing it throughout the building. When that water is running throughout all the piping, it has the potential to pick up various contaminants depending on the type of system it is running through.

For example, copper, brass, and steel systems can corrode and experience scale buildup over time. That corrosion and scale buildup can impact the drinking water in a system — affecting everything from taste and odor to even bacterial formation.

Other piping systems, such as CPVC, use glues, cements and other chemicals to join the pipe to the fittings. These chemicals are not organic in nature and have the potential to pose risk if they seep into the drinking water system.

The safest material for drinking water requires a durable system that is immune to corrosion and scale buildup and does not use chemicals for joining purposes. This is why PEX is quickly becoming the professionals’ choice for commercial domestic water piping projects.

PEX, a flexible, durable, polymer piping product, has been used successfully in homes and businesses for decades. It naturally resists corrosion and scale buildup and offers several different joining methods, all of which do not use chemicals — or open flame.

Best of all, because PEX is flexible, it greatly reduces the amount of connections needed in a system. This gives you the benefit of a high-performing, durable, long-lasting solution that also helps you with labor time and installation costs.

U.S. Boiler Company has released the new Alta Combi boiler, the industry’s first and only gas-adaptive combi boiler with 10:1 turndown.

The all-new Alta Combi high efficiency condensing boiler offers best in class, next-generation gas adaptive technology that provides the shortest installation time and lowest operating costs. The powerful gas-adaptive technology offers true “no touch” combustion setup. There are no manual throttle or offset adjustments. Engineered for five-minute start-up, the boiler’s control system provides continuous, automatic self-calibration of burner combustion by adapting to component wear, variations in fuel, environment, and vent air pressure to provide safe, efficient, and clean combustion at all times.

Converting from natural gas to LP is simple. No additional parts or conversion kits are needed. The Alta also includes a sensor-less reset, which performs the functions of a conventional outdoor reset without the need to install an outside sensor.

Domestic hot water response time is virtually instantaneous. Domestic hot water temperatures are maintained under all demand conditions, and the unit’s DHW recirculation system can be set to either economy or comfort mode.

At 95% AFUE, The Alta Combi is currently available with 136 MBH DHW input (3.7 GPM) / 120 MBH heating input. However, stay tuned! U.S. Boiler Company will be releasing a larger Alta Combi boiler (200 MBH DHW / 150 heating) and numerous heating-only Alta models (80, 120, 150 and 180 MBH) later this year.

Each Alta comes with value-added components and features, including an AltaFastPipe primary/secondary piping assembly, lift-away front and side panels for three-sided access, boiler flow safety switch (UL353) and display indicator, ProPress compatibility and a five-year parts warranty.

The Rinnai® BMS Gateway creates a unique solution for hot water management 

Having a way to control and monitor hot water usage creates efficiencies for business leaders and facility managers but is often critical to keeping businesses’ doors open. That’s why Rinnai has launched the Building Management System (BMS) Gateway, a new product that will provide commercial and vertical markets a software system used to remotely control and monitor Rinnai Commercial Tankless Water Heaters. 

“Our brand promise is Creating a Healthier Way of Living® and we are focused on providing simple, affordable solutions for businesses,” said Frank Windsor, President of Rinnai North America. “The Rinnai BMS Gateway is the next step to empowering customers to actively manage hot water and help it run seamlessly through any building.” 

Whether using the optional Touch Screen User Interface that acts as an enhanced controller or working directly through the BMS Gateway, businesses can remotely turn tankless water heaters on or off, adjust water temperature, monitor flow rates, operation hours and more. The BMS Gateway and Touch Screen User Interface also allows up to 15 view-only parameters such as water flow rates, combustion cycles, operation hours and error code history. 

Businesses can pair up to six Rinnai Commercial Condensing Water Heaters per BMS Gateway, with up to four gateways per network, for a maximum of 24 tankless units connected thereby enabling greater reach. Additionally, the BMS Gateway works with Rinnai CU199 and CU160 condensing tankless models and uses BACnet, Modbus or LonWorks communication protocols. 

“Many commercial settings, such as school campuses, healthcare facilities, multifamily and government buildings, are often required to have BMS capabilities,” said Dale Schmitz, Rinnai Marketing Segment Manager. “We are now able to provide customers with an intuitive gateway to remotely control and monitor Rinnai Commercial Tankless Water Heaters through a customer-supplied BMS system.” 

Businesses can upgrade their tankless water heaters to include the BMS Gateway or install a whole new system and save thousands in acquisition, maintenance and energy costs. Rinnai tankless units offer precise load tracking, so the amount of energy consumed is directly correlated to the amount of water heated at any given time versus having to heat and re-heat stored water with boilers and tanks. 

 The Rinnai Tankless Rack System comes in Wall-hanging or Freestanding configurations, includes factory assembled manifolds for gas and water that are tested and warrantied, provides built-in redundancy and can be combined with up to 24 units to provide 4.8 million Btu. 

Rinnai is here to solve the needs of businesses while also providing easy, affordable turnkey solutions. With the latest and greatest addition of the BMS Gateway, Rinnai is here to keep hot water running for businesses to stay in business.
