The gas tank has to come out to change it as the pump is in the tank.
The formula for calculating the efficiency of a heat pump is the ratio of the heat output to the energy input, expressed as a percentage. It can be calculated using the formula: Efficiency (Heat Output / Energy Input) x 100.
q= p/(row)gh
Pump Selection - Things to Consider•Pump location■ Equipment room or plenum?■ Close to occupied areas?•Available space■ Installation footprint■ Maintenance footprint•Maintenance requirements■ Parts availability■ Special skills, tools etc.•Reliability•Hydraulic requirements■ Flow rate, head, efficiency, horsepower■ NPSH

The formula for the coefficient of performance (COP) of a heat pump is the ratio of the heat output to the work input. It is calculated as COP Qh / W, where Qh is the heat output in watts and W is the work input in watts. A higher COP value indicates a more efficient heat pump.
