Geothermal

Ground source heat pumps (GSHPs) are a cornerstone of modern, eco-friendly energy solutions offered by Jim Godbout Plumbing and Heating. These electrically powered systems harness the earth's stored energy – its greatest solar collector – to provide heating, cooling, and hot water. GSHPs operate by utilizing the earth’s relatively constant temperature, making them highly efficient for both residential and commercial applications.

​

The working mechanism of ground source heat pumps involves either closed or open loop systems, which can be installed horizontally, vertically, or in a pond/lake, depending on the land area, soil, and rock type at the site. Closed loop systems circulate water or an antifreeze solution through underground pipes, absorbing heat from the earth in winter and reversing the process in summer to cool buildings while generating free hot water. Open loop systems function similarly, suitable where there's an adequate water supply and feasible open discharge. Given the global energy challenge and the finite nature of fossil fuel reserves, renewable energy sources like GSHPs are vital for energy security, climate protection, and cost stability.

 

At Jim Godbout Plumbing and Heating, the focus is on building the right system. While Europe mandates geothermal use, and many geothermal systems have been suboptimal, their approach is innovative. They drill 1500 foot wells and construct shell and tube closed loop geothermal systems with Water Furnace heat pumps. This system consistently achieves a Coefficient of Performance (COP) over 5, drawing an average temperature of over 50 degrees Fahrenheit even in the coldest months, often eliminating the need for solar or fossil fuel backup.

 

While the initial cost of a geothermal system is considerable, spreading the investment over a mortgage term makes it economically feasible, with a payback period of about 5-6 years at current fuel prices. The operational costs and carbon emissions for homes, especially for larger ones, are significant factors today. Geothermal systems not only reduce these operating costs but also contribute to reducing carbon emissions, making them a crucial component of sustainable living.
