Heat pump sizing – How do you find the optimum solution for your project?
Are you facing the challenge of heat pump sizing or looking to optimize the controls and components of existing systems? Proper heat pump sizing is essential, as it directly impacts the efficiency, cost-effectiveness, and overall customer satisfaction of your project.
With Polysun, you have access to professional planning software that supports accurate and efficient heat pump sizing. By simulating heating loads and building-specific heat demand, and by matching the heat pump output accordingly, you can evaluate different system options and gain the planning confidence you need.
Heat pump size: comparison of variants and optimisation
An incorrectly dimensioned heat pump can lead to increased operating costs, reduced performance and premature wear. Without simulating the different system variants, there is uncertainty as to whether you will achieve your goals such as economic efficiency, CO2 savings or self-consumption.
Polysun contains specific manufacturer data and component libraries. This enables you to find the optimum variant to achieve your goals for your problem.
