**5. Conclusions**

In this chapter, a novel PV/T with PHE array coupled to a low expense geothermal copper pipe array and heat pump system is installed in the JWL poultry farm. A numerical model is established and has a good agreement with experimental data within a 15% error. In the meantime, the yearly system energy output is predicted based on the Newark-on-Trent of Nottinghamshire, UK weather conditions. Moreover, the comparisons of the gas cost, electrical cost and CO2 emission are investigated between the gas burners and hybrid renewable heating systems. Some significant outcomes are obtained as below:
