While geothermal technology for heating and cooling has been around for decades, it has improved dramatically over the past twenty years. The market has seen a dramatic increase since the advent of two-stage equipment and efficiency ratings twice as high as conventional cooling systems and four times as high as fossil fuel heating systems. It’s not just homeowners who love this technology but also the utility companies who offer attractive rebate incentives for those who choose qualified installation contractors to design and install their new systems. Here at BEM, we design and install the industry’s best technology in Long Island homes and secure attractive rebates from PSEG, which ensures that, combined with the utility savings, our customer’s equipment can pay for itself. Call BEM for details.
An open loop system is connected to groundwater such as a well and pumps directly to an indoor heat pump. A closed loop system consists of underground piping which contains an anti-freeze solution which absorbs or sheds heat to or from the surrounding earth. The fluid is circulated through the heat pump for the heat and cool system. Call BEM to discuss which option is best for your home.
A “Water To Air” system absorbs heat from water into the refrigerant in the heat pump. The heat is then transferred to the circulating air in the home’s central system. In cooling mode, a geothermal system operates similarly to a conventional cooling system. It absorbs heat from the air into the refrigerant and then transfers it to the water. This is the most commonly used system.
A “Water To Water” system operates in the same way as a WTA system with one exception. The energy is transferred to a closed hydronic loop within the home and not the air. The water (warm in winter, chilled in summer) within this closed hydronic system is circulated throughout the home to fan coils and radiant floor panels. Suitable for homes with radiant heat as its primary heating.
