› Effects on self consumption case study › PV install: 15 kW PV peak, 15’000 to 17,000 kWh/year

• No optimisation of system: 25 to 30 % • Programming Timers to noon: 40 to 45% • Software with predictive data: 50 to 55%

• 55%+ when using car charging at home

Testing Testing and standards

Testing Heat Pumps STIEBEL ELTRON

Company Presentation STIEBEL ELTRON 18

› Most important test standards for Hydronic heat pumps:

› HP Keymark New standardised test reports for a heat pump in the European market › DIN EN 14511 European test standards for heat pumps, A/C’s and chillers › EHPA seal of quality Going further than DIN EN14511. Defines minimal COP’s, measures

efficiency and noise emissions within +/- 5% tolerance

Testing Heat Pumps STIEBEL ELTRON

Company Presentation STIEBEL ELTRON 19

› Impressions test facilities:

Climatic chamber Air sourced heat pump (NTB Buchs)

Sound emissions testing Domestic hot water heat pump

Noise emissions: Look beyond the data sheet! STIEBEL ELTRON

Company Presentation STIEBEL ELTRON 20

› Sound power vs sound pressure:

• Sound power level (Lw) is measured dB to test standards in a sound lab.

• Sound pressure level (Lp) is measured on site. Related to orientation, situation, distance and sound power level

› Regularities and laws: • Both values can’t be directly compared without further information • Relations are logarithmical not linear • Duplicating the distance to the source reduces sound pressure level

for 6 dB • 10 dB difference is perceived as double the noise • Using two identical units will be 3 dB louder than just one
