 ### HVAC Load Calculator - Manual J Calculation | ServiceTitan

The heat flow rate can be calculated as . h = (4.2 kJ/kg o C) (1000 kg/m 3) (10 liter) (1/1000 m 3 /liter) ((100 o C) - (10 o C)) / ((30 min) (60 s/min)) = 2.1 kJ/s (kW) The 24V DC electric current required for the heating can be calculated as. I = (2.1 kW) (1000 W/kW)/ (24 V) = 87.5 Amps

Get A Quote Once the load is established, then we can calculate the necessary flow rate. GPM = Heat Load/ 500 ^T. GPM describes the flow rate; the heat load is expressed as BTU/H, which is the heat loss of the building at design conditions. ^T is the temperature difference that occurs from the supply to the return when water is circulated through the radiation.

Boiler Ratings and Boiler Load . The oldest method of rating boilers, still used to rate small boilers, is by horsepower (hp). One horsepower is defined as the ability to evaporate 34.5 lbs of water into steam at 212 deg. F and above. Large boiler capacity is generally given in lbs of steam evaporated per hour, under specified steam conditions.
