Onsite-testing heatpump output - continued:

Formula to Calculate Kilojoules;

4816 x LOAD x RISE / 1000/60/TIME =

kW OUTPUT

LOAD = Tank capacity plus plumbing

TIME = Duration of test

RISE = 10C

4186 x 210 x10/1000 = 8790kj

EXAMPLE:

200Lt buff10Lt plumbing,

LOAD = 210

Temperature rise was 10C,

RISE= 10

4186 x 210 x10/1000 = 8790kj

Conversion kj to kW;

Stopwatch says it took 15 minutes,

TIME= 15

8790/60/15 =

9.77kW output
