Designing Your Ontario Geothermal System

The design of a geothermal heating and cooling system is critical to its success. Reaping the full benefits of your investment depends entirely on what happens upfront during the planning process, so take the time to work with an established company like The Hayter Group..

The first step involves gathering accurate data. The land area and condition determine the type of loop system selected, while the size of the building and its heating and cooling load determine how much energy is needed to maintain a stable temperature. You should also factor in the amount of pipe needed, and the selection of a heat pump.

Determining the building’s energy needs as precisely as possible is key. In addition the size, insulation levels, climate and the rate at which the building loses or acquires heat are chief concerns when calculating the energy load. Window placement also contributes, and any additional requirements, such as an added loop for hot water or the desire to heat a pool, must be factored into the calculations as well.

Designs also take into account the predicted amount of energy needed to operate the system. Selecting a properly sized heat pump is critical: It must have the right capacity for the structure. A heat pump that’s too big wastes upfront costs and energy, while one that’s too small may mean relying on other heating methods that will also add to costs and reduce efficiency. The loop design, the ground temperature and the pumping speed all play a part in making these calculations. In a retrofit, the existing delivery system must also be considered.

Gathering information on all these elements ensures that we can create a system that will deliver optimum efficiency. A geothermal heating and cooling system is a positive and long-reaching investment; taking the time to do it right will bring the greatest rewards.
