Geothermal systems are an efficient and environmentally friendly technology to cool and heat buildings. However, the system installation remains expensive making its expansion difficult. Versaprofiles, a Canadian enterprise, has developed a thermal enhanced pipe especially designed to geothermal applications. This pipe allows to reduce the system cost, improving its performance. Experimental tests in systems using standard and enhanced pipes will allow to compare the two systems performance, searching to assess the advantages of the thermal enhanced pipes.
