From water temperature control to complete zone management

Different parts of a hydronic heating system require different forms of control. IVAR’s Mixing & Control range provides components that can be selected individually or combined as part of a wider system design.

Mix and distribute

3 and 4 port rotor mixing valves regulate and distribute water within heating and cooling circuits. Manual adjustment or motorised operation provides options for different system-control requirements.

Choosing the right IVAR mixing and control solution

Product selection will depend on the system layout, required flow rate, operating temperatures and the level of control required. The individual category and product pages provide sizes, Kv values, operating specifications, product codes and technical downloads where available.

For underfloor heating and radiant systems, the Mixing Kits range provides integrated mixing and circulation options. Where the requirement is specifically to mix or divert system flow, explore the 3 & 4 Port Mixing Valves range. For room thermostats and multi-zone system management, see IVAR Heating Controls.

IVAR mixing and control FAQs

What products are included in IVAR Mixing & Control Solutions?

The range includes 3 and 4 port rotor mixing valves, underfloor heating and radiant-system mixing kits, motorised valve control, digital thermostats and multi-zone wiring centres.

What is the difference between a mixing valve and a mixing kit?

A mixing valve regulates or distributes water within a heating or cooling circuit. A mixing kit combines mixing with other components such as circulation pumps, temperature control and connections to provide a more complete solution for applications such as underfloor heating.

Can IVAR mixing valves be automatically controlled?

Yes. IVAR rotor mixing valves can be manually operated or fitted with suitable motorised heads for automatic control.

Does IVAR provide controls for multi-zone heating systems?

Yes. IVAR wiring centres can connect room thermostats and heating zones, while suitable models can also provide control signals for electrothermal heads, pumps and boilers.
