Analysis of Economical Efficiency of Low-Temperature Heating Utilization and HW Supply in Combination with Solar Collectors in Housing and Municipal Sphere
Economical system application of heat supply with using solar collectors in combination with heat pump is not only a question of return of investment. It is also the question of priorities, life style and ecology.
Many methods, studies and tables with presented data about energy consumptions for various ways of heating to determinate return of investment.
Basic condition of economical advantageousness of heat pump utilization instead of classic way of heat production in term of total year costs is that those are lower than total year costs for comparative classic way of heat production. Because difference in investment costs of comparative heating systems and heat pumps is almost always in the disadvantage of heat pump system.
