Product FAQ’s

Answer: By using the constant and favourable temperature of the earth as its heat source, 75% of the heat delivered to the building by our pump is renewable energy, therefore efficiency is greatly improved. Mechanical simplicity and the constant earth temperature assure longer equipment life and less maintenance.

Answer:  Direct Energy offers both lower installation costs (due to less excavation costs) as well as a more efficient use of the earth heat by selection of world-leading direct expansion and water-loop Geothermal Heat Pumps.

Answer: Direct Energy systems are selected for their high efficiencies and proven reliability.

Answer: Direct Energy systems are selected for their high efficiency.

Answer: Earth Loops can be installed horizontally in pits or trenches using excavators or trenchers, as well as vertically or diagonally using small bore drilling equipment.

Answer: Loops for a 10.5kWth system in pits and trenches can be installed in a single day. Loops using vertical and diagonal bores can be installed in two days.

Answer: In the 1970’s, the manufacturers began research and development of Direct Energy’s systems.

Answer: Yes. Existing ducting and air handlers can be used with minor modifications and the addition of the earth loops and compressor unit.

Answer: U.S. EPA and DOE have determined that ground source heat pumps have the lowest environmental impact of all heating systems and they reduce energy consumption and corresponding emissions up to 72% when compared to electric heat strips and standard air conditioning. The refrigerant used by Direct Energy is not toxic, and is the same as that currently used by a majority of the HVAC industry.

Answer: The two controls in Direct Energy’s DX system are simple mechanical controls that respond directly to the temperature and velocity of refrigerant flow through the system. They modulate the amount of refrigerant in circulation to assure optimum efficiency at all times. By eliminating sub cooling in the condenser, the system operates at lower refrigerant “head” pressures with increased mass flow, which reduces energy consumption and increases heat transfer system reliability and useful life.

Answer: Yes. The Direct Energy water heating options include de superheating (providing “free” hot water in the cooling mode) and integrated “on-demand” for year-round domestic hot water. This unit can also provide hot water for radiant in-floor heating.

Answer: Yes our systems are rated according to ARI (the Air Conditioning and Refrigeration Institute).The average heating COP is 3.9, with a cooling mode EER of 17. The system is ETL safety listed and qualified under the EPA EnergyStar® program standards.
