Go to Heat recovery tool and press "Lets Start"
In Step 1, your choices will determine the system architecture necessary to make your heat available for recovery and reuse.
Please decide whether the excess energy can be used directly without additional temperature increase:
• Example: If your excess heat source temperature is around 30°C, and you want to supply 25°C hot air to your greenhouse, you can use that heat without additional temperature increase (select “Yes”). If you have the same source temperature, but you want to supply heat to your building, where you will need a higher temperature (i.e. 60°C) please select “No”.
The next question is whether you will use the heat at your own facility or supply it to an external system.
• Example: If you want to use your excess heat from production processes to heat your nearby office, select “Use excess energy at own facility (Booster heat pump is at the Supplier).” If you want to supply it to district heating or another external system, select “Supply excess energy to external (Booster heat pump is at the heat consumer).” In this case, a heat recovery unit makes sense to separate the hydronics and investments for components between the heat supplier and heat consumer.
Once you have selected both, a recommended system architecture will be displayed. For further explanation of the system and the questions please click on the info icons.
Now press “Next” in the top right corner to go to Step 2.
In Step 2 we are collecting information regarding the excess heat source, the medium which is carrying the heat, capacity, temperatures, media and profile. Please refer to “Diagram Info” if parameters are unclear.
As for heat recovery from air sources we target a fluid loop to the heat pump or HRU (depending on your system selection in Step 1) an Air to Water heat exchanger will be necessary to transfer the heat from the air heat source to the fluid. Please note that this additional heat exchanger will not be shown in the graphics but will be considered as additional CAPEX in the financial results.
Enter the capacity of your excess heat source. Next, enter the supply and return temperature on your excess heat source.
To determine how much energy you have annually available the next step is to gather information regarding your excess heat profile. You have two choices here to move forward. One way is to enter your yearly hours of excess heat available. For example, that could be your yearly operating hours of your cooling system.
The more detailed alternative is to select “Custom (set Daily & Weekly). In case your working and production hours are fixed from 7am to 7pm you can set this in the custom fields. You can also select the days in the week when the excess heat source is available. Also, in the last option you can customize the excess heat source capacity for each month, if necessary.
Press “Next” in the top right corner to go to Step 3.
Step 3 is like Step 2 but the focus here is on the site of the heat consumer.
Enter the capacity, supply and return temperature of you heat demand. Framing that in a scenario where recovering and reusing excess heat might replace your gas fired boiler you could simply use the capacity as well as the supply and return temperature of your boiler.
Like in Step 2, you have two options to set a demand profile in the tool, either setting yearly hours of heat demand or customize it by working hours, weekdays of operation and monthly capacity of your heat demand.
Press “Next” in the top right corner to go to Step 4.
In Step 4 the following data is necessary to evaluate the financial aspects of your potential excess heat recovery opportunity.
At first, please select your country and your electricity costs. The county selection is necessary to calculate the CO2 savings as the electricity mix varies from country to country. The electricity costs are crucial to calculate potential savings by electrification of your heating purpose. To compare the current costs with the potential of electrification please also provide the current costs for heating.
“Price heat sales” becomes crucial, if you are selling your heat to an external system.
Press “Next” in the top right corner.

Here, you can explore your heat recovery opportunity in a graphical way.
Available Excess Heat represents the total amount of energy per year that could potentially be recovered. Excess Heat Recovered represents the amount of energy that is utilized, depending on your demand inputs. In case a Heat pump is needed for your heat recovery project the compressor power will add additional heat which can be used which is stated in the light blue box.
In case there is more excess heat available compared to your demand there will be a part of your available excess heat that in un-recovered. This additional un-recovered heat can be used for example to supply it to a district heating network.
In case there is not enough heat available to fully cover your demand there will be an “un-covered” part which means your current heating system will still be needed but its load will decrease.
In relation to the recovered heat, you can see the energy required for the heat pump and pumps. The gap between the energy used by the heat pump and pumps and the recovered heat provides an initial overview of how much energy you can save by recovering and reusing heat.
Below, you can see your potential annual CO2 reductions. Please note that these savings assume that the heat consumer is replacing a gas boiler by reusing excess heat.
In the financial part, you can explore the financial aspects of the heat recovery opportunity. If you have chosen to supply your excess heat to external there will be a suppliers and consumer perspective. Each perspective has accordingly it´s individual CAPEX, OPEX and PAYBACK.
Investment (CAPEX): On the left, you get an initial overview of your capital expenditure. Please note that distribution and connection costs are not included in the CAPEX.
Operating Costs: Further to the right, you can find your operating costs, segmented into:
• Electricity for Pumps
• Electricity Consumption of the Heat Pump

| Available Excess Heat | This bar illustrates the total annual excess heat available from the identified heat source. It is calculated based on the capacity inputs of the excess heat source and its operational profile (e.g., hours of operation and intensity). The available excess heat is the maximum recoverable thermal energy from processes or sources such as industrial waste heat, exhaust air, or geothermal systems. Understanding this value is critical for designing the heat recovery and heat pump system to optimize energy utilization. |
| Heat demand |
This bar shows the total annual heat demand of the heat consumer. It is calculated based on the specific heating capacity requirements and the operating profile inputs of the consumer.
The heat demand represents the amount of energy required to maintain the desired heating levels for the consumer’s needs, such as space heating, water heating, or industrial processes. |
| Excess heat Recovered |
This portion of the bar shows the amount of excess heat that is successfully recovered from the excess heat source.
Details:
o Green Section:
This indicates the recovered excess heat that is directly utilized to meet the heat
consumer’s demand.
o Box on Top of the Green Bar:
This section represents the additional heat supplied by the heat pump system,

The compressor boosts the temperature of the recovered heat to meet the consumer's
heating requirements.
Implications:
o Demand exceeds the sum of the Available Excess Heat:
If the heat demand exceeds the sum of the available excess heat and the additional
heat from the compressor, there will be unmet heat demand. In this case, an auxiliary
heat source (e.g., a gas boiler) will be required to bridge the gap.
o Available Excess Heat exceeds the Heat Demand:
Conversely, if the available heat exceeds the demand, some of the excess heat remains
“un-recovered” and could potentially be utilized for other applications or systems in
the future.

country-specific electricity grid mix (e.g., renewable vs. non-renewable energy
sources).
o Baseline Comparison:
• The CO₂ emissions from the heat recovery system are compared to those of a
conventional heating system, such as a gas boiler or oil furnace.
• The difference between the emissions of these two systems represents the annual CO₂
reduction.
Additional Context:
o Environmental Benefits:
By using waste heat recovery, facilities can significantly cut down on their carbon
footprint, contributing to global efforts to combat climate change.
o Impact of Energy Mix:
The electricity mix in the selected country plays a critical role in determining the
overall CO₂ reduction. For example:
• A country with a high share of renewable energy in its grid mix will result in
greater CO₂ reductions.
• Conversely, a grid mix heavily reliant on coal or gas may reduce the CO₂
savings, though the heat recovery solution still provides environmental benefits
compared to gas or oil heating.
o Efficiency Gains: :
Heat recovery systems are typically more energy-efficient than conventional heating
systems, which further amplifies the CO₂ savings.
Broader Implications:
• This metric highlights how heat recovery solutions not only save energy costs but
also align with sustainability goals, regulatory compliance, and corporate social
responsibility initiatives..
• Facilities implementing such systems can benefit from carbon credits or subsidies in
regions where governments incentivize CO₂ reduction projects.
