"Using the constant temperature of the ground as a heat source and sink saves 30 -70% of our energy requirements. We thoroughly recommend that others consider Direct Energy’s direct geoexchange technology for their space and water heating and cooling. Certainly, anyone building a new home or office must consider this technology. And, as we have demonstrated, it’s not hard to use it in retrofitting an 80+ year old historic home."
Joyce Marks B.Arch Mt Eliza, VIC
"Complex and very thorough testing has proved that the direct exchange ground coupled heat pump system is the best available solution for providing continuous, reliable, maintenance free and cheap cooling of sensitive scientific equipment in a remote desert environment."
Dezso Kiraly, ASKAP, ATNF, CSIRO, VIC
“The temperature is constantly stabilised and people immediately notice there is no noise, there’s no heat blowing on your face – the temperature is just comfortable.”
Mr Weinman, North Caulfield, VIC
“The technology is good for the environment and it not only adds intrinsic value to my home, but provides immediate savings in my energy bills. My electricity bill is now around $100 when it was $500.”
Dean Weinman, North Caulfield, VIC
"Direct Energy’s technology has cut our energy consumption by 75 % and our fossil fuel usage by more than 80%. The payback period of 6 years is considered by the club to be completely acceptable given the expected 30 to 50 year life of our building.
Since commissioning, forecasted savings have been exceeded with several spin-off benefits."
Murray Neilson, B’Rush Ski Club, VIC
