Tankless Water Heaters

Small and wall-mounted, tankless water heaters produce hot water on demand for everything from residential showers to industrial facilities. Without the higher energy consumption and costs or space requirements that come with a tank-style water heater, tankless water heaters using water ejectors are efficient, convenient, and flexible.

At Baelz North America, we offer controlled water ejector technology for lasting performance and reduced operating costs in your tankless water heater. These controlled ejectors effectively regulate water temperature, generate water circulation, manage circulation volume per a system’s heat requirements, and compensate for differential pressure fluctuations.

How Tankless Water Heaters Eliminate the Need for Your Hot Water Tank

Tankless water heaters rapidly heat water as you need it, rather than heating and reheating large volumes of water in a storage tank-style system to maintain a constant temperature. In a traditional water heater, hot water exits the tank when a system calls for it and then fresh, cold water flows into the tank to replenish it, mixing with whatever hot water remains. The system must heat the contents of the tank back to the desired temperature, and maintain it to account for heat loss to the tank’s ambient environment.

So, how do tankless water heaters work? Tankless units heat water only when you need it, eliminating any unnecessary heating or standby energy loss. The water heats using an electric heating element or a gas burner as it travels through a coil system. In tankless heaters using water ejectors, the ejectors efficiently deliver hot water by converting the water pressure of the motive fluid into velocity energy, creating a vacuum with a suction effect that pulls water through the system to exit an outlet pipe. The water ejector design makes systems such as industrial tankless water heaters highly effective for hot water delivery.

Benefits of Tankless Water Heaters Using Water Ejectors

By only heating water when it’s necessary, tankless water heaters with water ejector technology offer numerous benefits, including:

  • Greater efficiency. With tankless units, you won’t experience heat loss like you will from a water tank. Tankless varieties also consume less power, making them highly energy efficient.
  • Lasting, reliable performance. Traditional water heaters have a shorter lifespan, averaging 10 to 15 years, while tankless systems and water ejectors generally double that and typically require less maintenance for reliable functionality. Tankless models also will not run out of hot water as storage tank models do.
  • Utility and maintenance savings. While the upfront cost of a tankless water heater is higher than traditional tank units, you’ll offset this with reduced utility bills and operating expenditures. Heating water on demand consumes less energy. Also, as both tankless heaters and their water ejectors are longer-lasting systems, you’ll also save on maintenance costs and part replacements.
  • Enhanced safety. Tankless water heaters are safer to use because they don’t store large amounts of hot water, saving users from potential burns and making for a safer workplace. Tankless systems also have less capacity for property damage as they’ll never release gallons of hot water that might harm equipment, flooring, and more.
  • Reduced space needs. Tankless water heaters are wall-mounted, allowing you to install the compact, low-profile box with more flexibility in location. You simply need access to a power supply and the water line. Placement for traditional water heaters, however, is dependent upon space and where you can fit the tank. For industrial water heaters, tanks can eat up valuable facility space.

Installing Tankless Water Heaters

Tankless water heater installation is more flexible than with traditional storage tank water heaters. However, consider the following when choosing a tankless model and installation location:

  • Fuel type. Electric and natural gas models are available. Be sure to verify the fuel type and flow rates for your location before selecting a model.
  • Temperature rise requirements. Understanding your anticipated temperature needs and just how much the water heater will need to raise the incoming water supply’s temperature will also help determine the adequate model for your application.
  • Location. Tankless models need to connect with incoming water supply lines and outgoing pipes for water delivery. Gas-powered models require gas supply lines while installers can plug in electric models.

Our high-quality materials, durable components, and accessible, easy services make our tankless water heater parts an excellent value for the money now and over time.

Control Valves

Choose from two-way and three-way electrical and pneumatic control valves suitable for water, steam, oil, and other fluids. A range of diameters 15 mm to 300 mm are available, with pressure ratings of PN16, PN25, and PN40. All models have a wide operational temperature range.

Water Ejectors

Water ejectors use the Venturi principle to create a high-velocity stream of hot fluid that draws fluids into low-pressure, cold fluid zones. The two fluids mix in the cylinder, then move into a diffuser where the pressure is adjusted. Our line of water ejectors have nominal diameters from 15mm to 300 mm, and feature a simple design with few moving parts and an energy-efficient pump. The result is a hydraulically stable device that reduces the number of data points to monitor.

Temperature Controllers

Baelz temperature controllers use WinBAS control technology software, a highly flexible and modular software solution. The system communicates with Modbus RTU and can connect to PROFIBUS, PROFINET, OPC UA, BACnet, and M-Bus. These temperature controllers provide automated control to meet the needs of many types of processing centers and industrial facilities.

Control Loop Technology

Control loop technology can provide complete oversight and automation for smart, reliable, and efficient fluid management.

Tankless Water Heater FAQs

Are Tankless Water Heaters More Efficient?

Tankless water heaters are much more efficient than traditional tank water heaters, offering 25-80% greater efficiency. Because tankless heaters only heat water on demand, they do not cause standby energy loss. Gas tankless heaters, in particular, are even more energy-efficient, offering between 85% and 98% efficiency.

How Long Do Tankless Water Heaters Last?

Tankless water heaters can last over 20 years, while traditional tank heaters only last 10 to 15 years. Part of what makes tankless heaters so durable for longer is the ease with which their components can be replaced.

Does My Tankless Water Heater Need a Pressure Relief Valve?

Different models of tankless water heaters may or may not need a pressure relief valve. Most models include built-in safety mechanisms, but some need a pressure relief valve due to local code requirements or specific demands of the building’s systems. A tankless water heater expert can help determine if your particular system and heater need a pressure relief valve.
