Tank for hot drinking water

Storage of hot drinking water at maximum 90°C

Tank temperature sensor

Measures the temperature of the water in the tank

Test pressure

Maximum pressure that a component can withstand for a short time. This is how tightness can be checked.


Measures the temperature and controls heating system accordingly

Thermostat valve

Mechanical controller that measures the temperature and then controls the flow volume of heating water to maintain the desired room temperature

Thermostream principle

Mixing the cold return water with the hot flow water raises the water temperature


Is used to reduce the pressure of liquids that are added.

Throttle curve

Change rate of the flow of a centrifugal pump subject to the discharge head

Transmission loss

Loss of thermal energy due to the transport of the heat carrier through the heat conductors
