Heat pump sizing - method

Program that indicates how to size a heat pump starting from environmental and local data or via the average gas consumption in recent years. It also indicates the electricity consumption that must be faced to obtain the indicated result

Introducing this amazing program that will completely change the way you approach heat pump sizing. In an era where energy efficiency and environmental sustainability have become top priorities, selecting the right heat pump is a very important decision.

This program was designed by Itieffe to simplify the sizing process, making it more accurate and based on concrete data. We will start by analyzing the place where you want to install the heat pump and by evaluating your gas consumption history over the last few years. This data will form the basis for calculating the ideal heat pump size for your specific needs.

But this program is much more than just a calculator. We will also explore the fundamentals of heat pump sizing, understanding the importance of climate variables, heating and cooling needs, and the energy performance of the pumps themselves. It will be an educational journey that will enable you to gain a thorough understanding of how heat pumps work and how you can maximize their efficiency.

This program has been designed to be your trusted companion in the heat pump decision-making process. Whether you're an industry expert, a homeowner or just curious, we're here to help you size your heat pumps intelligently and sustainably.

Let's start this journey together, starting from where you are and your history of gas consumption in recent years, to create a more efficient and ecologically and economically sustainable future.

Let's analyze the program

Report that indicates how to size a heat pump starting from environmental and local data or through the average gas consumption in recent years.

Different from the program that performs the same calculation: "Heat pump sizing - calculator"

It also indicates the electricity consumption that must be addressed to obtain the indicated result

ATTENTION: it does not replace the work of the heating engineer.

Instructions

The program is easy to use and anyone can use it, (even just to get feedback).

Let's start analyzing the first method:

1 - choose the country and the climatic zone you are interested in by searching the link inserted;

2 - report the values from the documents: "Indicative data for countries and climatic zones";

We report the project values: internal and external temperature, net area of the affected room, ETH from the energy performance certificate (APE), the daily hours indicated by the climatic zone, enter the number of members of the household.

3 - Let's read the desired result, that is the nominal thermal power of the heat pump which in our case is equal to 7,95 kW.

4 - insert the COP value from the data provided by the manufacturer (if you want to calculate the electrical consumption of the machine);

5 - take note of the value of the electrical consumption of the machine which in our case is equal to 2,27 kW for each hour of continuous operation.

Let's now analyze the second method:

6 - make a choice between methane per m³and LPG per liter;

7 - enter the boiler efficiency by choosing the values in the drop-down menu;

8 - insert the value of the gas consumption used for the year (better if you take several reference years and make the average);

9 - we read the result sought and that is the nominal thermal power of the heat pump which in our case is equal to 7,8 kW;

10 - insert the COP value from the data provided by the manufacturer (if you want to calculate the electrical consumption of the machine);

11 - take note of the value of the electrical consumption of the machine which in our case is equal to 2,16 kW for each hour of continuous operation.
