The thermostatic mixing valve ESBE VTA 372 is designed especially for floor heating systems that require scalding protection from hot water. This protection is necessary for both the floor pipeline and the floor itself. Scald Safe means that in the event that the return water fails the incoming hot water is automatically shut off ensuring no uncontrolled temperature rises.

The version of the ESBE VTA 372 thermostatic valve sold here has a lower temperature setting of 20° making it suitable for curing a screeded floor at commissioning. The upper temperature setting of 55°c is the highest any underfloor heating system will be set at to avoid damage to floor finishes. (In many cases it is unwise to set it as high as this)

The wax element reacts on the water temperature and moves the cone to mix the return water from the underfloor heating circuits and and hot water flow from the heat source achieving desired, set mixed temperature.

ESBE Valves are the industry leading solution for control of your underfloor heating. Designed and made in Sweden since 1906, ESBE valves guarantee quality and performance for your underfloor heating system at it’s very core. Easily control the flow and temperature within the underfloor heating system to ensure it works optimally at any temperature between 20°c and 55°c depending on what is required. The desired temperature can be set with the easily hand-adjustable knob.

ESBE VTA 372 Usage

• Water distribution with antifreeze (≤ 50% glycol mixture)
• Closed water system
• Floor heating
• Cooling applications

NOTE:

With a Kvs value of 3.4, the ESBE VTA 372 is capable of managing underfloor heating systems up to 230m2, which is more than enough for even a 12-port manifold.

When you are looking at alternative non-branded products you may want to consider the lack of evidence based technical data available for such a key component!

 

Valve function

The valve has an asymmetrical water flow arrangement. It also has scalding protection – if the cold water supply is interrupted, the valve automatically shuts off the hot water supply.

Features

• Pressure class: PN 10
• Working pressure: 1.0 MPa (10 bar)
• Differential pressure: Mixing, max. 0.1 MPa (3 bar)
• The required temperature can be set by turning the knob under the top plastic cover.
