alpha check is a program for the calculation and optimisation of heat pump heating systems. It makes it possible to plan and optimise heat pump heating systems in a practical and user-friendly way. Important operating parameters such as annual coefficient of performance, temperature variation in the heat source and operating costs can be simulated or calculated easily on the basis of the system data provided by the heating system.
