would increased use of GHP systems affect electricity cost and availability?
The reduced peak load requirements would allow utilities to serve more customers and to lower fixed costs per customer, thus offsetting some increased variable costs. This would result in less cost per kilowatt, since fixed investment for new capacity is high. Installation: Are GHP systems difficult to install? Most units are easy to install, especially when they are replacing another forced-air system. This is known as a retrofit. GHPs can be installed in areas unsuitable for fossil fuel furnaces because there is no combustion and thus no need to vent exhaust fumes. Ductwork must be installed in homes without an existing air distribution system. Can I install a ground source heat exchanger myself? It’s not recommended. Thermal fusion of the pipe, drilling and trenching are procedures best handled by licensed professionals. Nonprofessional installations may result in less than optimum performance, which could cancel out anticipated savings How far apart are trenches and vertical boreho
