Heat pump sizing - calculator

Program that carries out the calculation for the sizing of a heat pump with division of the rooms. It also indicates how much energy must be consumed to obtain the indicated result.

We are pleased to introduce you to a powerful tool that will revolutionize the way you approach heat pump sizing. In an age where energy efficiency and sustainability are at the center of our concerns, selecting the right heat pump for your needs has become more crucial than ever.

This program was created by Itieffe to simplify the sizing process, making it more accurate, accessible and efficient. It doesn't matter if you are an experienced professional or a novice enthusiast, this tool will guide you through calculating the ideal size for your heat pump.

But we don't limit ourselves to numbers. We will also explore the key concepts behind heat pump sizing, including climate variables, heating and cooling needs, efficiency factors, construction type, etc. It will be an educational journey that will allow you to gain an in-depth understanding how the potential of heat pumps is calculated and how you can optimize their performance.

We hope this program will become your trusted ally in heat pump decision making. Whether you are a designer, technician, installer or simply interested in improving the energy efficiency of your homes, we are here to help you size your heat pumps optimally.

Let's begin this journey together, discovering heat pump sizing and its potential to optimize comfort and sustainability in our lives.

Heat pump sizing - calculator

Developed to carry out the calculation for the sizing of a heat pump with division of the rooms.

It also indicates how much energy must be consumed to obtain the indicated result.

ATTENTION: it is designed to bring rooms up to speed quickly (it does not replace the work of the heating engineer).

For those who intend to respect the climatic zones with the expected operating times and degree days, it is preferable to use: Heat pump sizing - method

Heat pump sizing - calculator

How many doubts there are in calculating the potential of a heat pump.

Each technician has his own overview which almost never coincides with that of his other colleagues.

With this simple program that anyone can use, we have tried to clarify some aspects.

Although simple, the program has a limited tolerance and more than acceptable results. Excellent substitute for expensive programs (and it's completely free).

Thermotechnicians can use it for a possible comparison with their own designs but they must not replace them (the work of a good thermotechnician is essential in any study).

The program is very intuitive. Just enter the required data and the result is immediate.

How to proceed

1 - enter the square footage of the rooms and the height

2 - insert the cardinal exposure

3 - enter the type of construction by choosing from the drop-down menu present

4 - enter the design external temperature by choosing the values in the drop-down menu (see External project temperatures)

5 - indicate in which unit of measurement you want to obtain the results by choosing the values in the drop-down menu (see Conversions work heat energy)

6 - indicates the potential that must be used in each individual environment in the unit of measurement chosen

7 - indicates the sum of the potential of each individual environment

8 - by choosing the percentage increase of the generator, it indicates the potential that is needed

9 - by entering the COP, it gives the amount of electricity consumption required for the operation of the PDC (see Calculation of power and motor currents for more detail)

Let's take an example by entering the project data

Summarizing what is described in the example:

Environment surface m²= 133

Cubature environment m³ = 398

Power required in the individual rooms = 13 kW (chosen unit of measurement)

Potential of the machine with a percentage increase of 10% = 15 kW

Electric consumption of the machine alone with COP equal to 3,5 - 4.2 kW.
