Hydronics and domestic hot water systems

Scroll to explore

Hydronic and domestic hot water systems use water as a heat carrier to provide efficient space heating, cooling and hot water for daily use. Neoperl's range of innovative valves and easy-to-use flexible hoses are specially designed to optimize energy efficiency and minimize heat losses in these systems. They also address the issues of scaling and fouling, which can negatively impact system performance and longevity.

There is a growing demand for hydronic systems that minimize energy consumption and reduce environmental impact. With our long-lasting and efficient valves and hoses that enable an optimized water circulation and heat transfer, we support industry players to meet these evolving needs of the market."

We offer solutions for different applications

Air-to-water heat pumps

Energy-efficient generation of space heating/cooling and domestic hot water. Enhance system efficiency with Neoperls products:

› Flexible hoses: easy to install, reducing noise and vibration
› NV/OV check valves: controlling flow direction, preventing cross flow
› Automatic backflush valve (ABF): keeping heat exchangers for the DHW loop free of scale

Solar hot water systems

Flat plate solar thermal collectors for domestic hot water can face scaling and fouling. Discover how our products maintain efficiency and extend system lifespan:

› ABF valve: keeps heat exchangers free of scale and deposits
› Flexible hoses: simple installation, manage thermal expansion/contraction, reducing stress on the solar system

Hydronic fan coil units

Fan coil units are widely used in buildings for effective heating and cooling. Neoperl components ensure an efficient and reliable operation of your system:

› Flexible connecting hoses: easy to install, reducing noise and vibration
› NV/OV check valves: controlling flow direction, preventing cross flow
› Flow regulators: controlling the flow rate

Instantaneous water heaters

Hydraulically controlled instantaneous water heaters, whether electric or gas-fired, benefit from precise inlet flow control. These tankless water heaters can have a life expectancy of over 20 years, which › Neoperl flow regulators support.

Circulators & recirculators

Circulating pumps and recirculating pumps move water in hydronic and domestic hot water systems. Integrated › check valves, sometimes referred to as “integral flow checks”, prevent gravity flow or ghost flow.

Thermostatic mixing valves

Regulate output water temperature at point of use or upstream in the system. Avoid cross-over flow (hot/cold) and excessive pressure build-ups with reliable › check valves for high tech applications or › check valves for high back pressure loads.

NV/OV check valves: Stay in control of flow direction

With their tight sealing mechanism, ultra-low head loss and high flow capacity, our NV/OV check valves prevent unwanted changes of the flow direction as well as cross flow between hot and cold water supplies.

Flexible connecting hoses: easy to install, reducing noise and vibration

Made from flexible, corrosion-resistant materials for easy installation in tight spaces and low maintenance.
Absorb vibrations from fan coil units, reducing noise transmission to the building.
Can handle thermal expansion and contraction, lowering stress on the hydronic system.
Available in various diameters, lengths, and with different fittings for secure connections.

Flow regulators: control flow rate to better control heat transfer

Neoperl flow regulators are the compact and economical option to control flow rate across the pressure fluctuations of municipal water systems (1 bar to 10 bar). Precise regulation of the water flow in hot water appliances helps control the heat exchange and the output of hot water.

HDS bypass valve: maintaning constant flow conditions

By maintaining a defined differential pressure, HDS dynamic bypass valves ensure constant flow conditions in the special modules of boilers. HDS valves limit the delivery pressure of circulation pumps and ensure a minimum flow in the boiler circuit. They also avoid annoying flow noise caused by excessive differential pressure.

Automatic backflush (ABF) valve: keeping heat exchangers free of scale and deposits

ABF valve to backflush and maintain DHW heat exchangers in systems with either forced circulation (pump) or natural convection (solar thermosyphon). The ABF valve periodically reverses the flow direction, removing any accumulated debris from the heat exchanger surfaces. This maintains optimal heat transfer and prolongs the system's lifespan.
