Manufacturer : WATTS EUROTHERM has ISO 9001 certification (2000 version) through the BVQI.

Market background and know-how : present since 1947.

Mixing cold and hot water in order to obtain water which is mixed at a stabilized temperature within one degree :
this is the important part.

A thermostatic mixing valve means substantially reduced water consumption, absolute safety – no water which is suddenly uncomfortably hot or cold – guaranteed regulation of flowrates, from the very lowest to the highest, piping and valves protected from limestone deposits, a larger reserve of mixed water at the desired temperature.

Easy to install, simple to maintain, attractively designed, WATTS EUROTHERM thermostatic mixing valves are the basic element for genuine comfort in all plumbing facilities.

Calculation software

The WATTS INDUSTRIES software package is designed
to validate the calculation carried out manually in order
to choose the right mixing valve (according to pressures,
pipe diameters, desired flowrate and number of points of use).

Calculation method :
1 – The software defines the Accumulated Flowrate
of mixed water by multiplying the number of equipment
items to be supplied by the usual unit flows.

2 – It calculates the Total Instantaneous Flowrate to be
provided by the mixing valve. Depending on the type of
worksite (3 types), it chooses the reduction coefficient of
flows corresponding to the quantity of equipment items
to be supplied.
It multiplies this coefficient by the accumulated flowrate
in order to obtain the instantaneous flowrate.

3 – Then the software chooses the thermostatic mixing valve
which will ensure the regulation at this instantaneous flowrate
under the dynamic pressure (b. = bars) available for its operation.
