Heat up the energy-saving analysis of pump water heater
From;    Author:Stand originally
With heating 10 tons of water are exemple (heat 55 degrees of) :
Hot pump year power consumption is:
Environmental temperature Entire season adds quantity of heat (KW) Energy-saving effect compares corresponding season Full quarter power consumption (KW)
Winter (10 ℃ ) 47160 3.15 14972
Transfer seasonal (22 ℃ ) 73260 3.76 19484
The summer (30 ℃ ) 28260 4.35 6497
Annual total power consumption (KW) 40953
Average power consumption of every tons of water (KW) 11.2
All sorts of the sources of energy run correspondence cost is comparative (Real calorific value of = of thermal efficiency of calorific value × )
Sort of the sources of energy Calorific value Thermal efficiency Real calorific value
Heat up pump 860 kilocalorie / degree 380% 3268 kilocalorie / degree
Electric power water heater 860 kilocalorie / degree 95% 817 kilocalorie / degree
Liquid gas 10800 kilocalorie / Kg 75% 8100 kilocalorie / Kg
Conduit is gas 3800 kilocalorie / cubic 85% 3230 kilocalorie / cubic
Derv boiler 10300 kilocalorie / Kg 80% 8240 kilocalorie / Kg
