HPS is a system designed for the measurement the heat power losses of boilers or other hydraulic appliances.
The electric heater - fitted within the hydraulic section of HPS - warms up the water in the circuit up to a programmed temperature difference compared to the ambient temperature, keeping this difference constant within some limits.
The electric power absorbed by the heater is measured during the test and it represents the heat losses of the appliance under test, apart from the losses of the HPS itself.
Tests are conducted automatically by the test bench
Tests to EN 15502-1
The internal losses of the HPS can be measured once, by the system itself. They are taken in consideration in the calculation of the losses of the appliance.
HPS works in combination with a Microplan test bench.
