Geothermal Hydronic Floor Heating

Combining radiant hydronic floor heating with our Geothermal heating system will provide a high level of comfort at low cost.

As an alternative to forced air heating and cooling via an air handler, our geothermal heat pump can also provide the most efficient heating and cooling source for any radiant hydronic heating system and chilled water for a fan coil cooling system. This feature can be incorporated without the need to ‘oversize’ the equipment.

Energy Savings

Studies have found energy usage averages 40% less in homes with radiant heating than with forced air heating – a big savings in your heating cost. Combine this with the efficiency of Direct Energy’s geothermal heating and you have a winner!

How Does Radiant Hydronic Floor Heating Work?

A radiant hydronic heating system circulates warm water through special tubing in or beneath floors to distribute heat. Radiant energy warms the surfaces of all objects which are in direct line of sight, including all floors, walls, furniture and people which can be ‘seen’ by the floor.

Radiant systems provide the inverse of conventional space heating patterns: they provide warm floors and cool ceilings, resulting in greater comfort and energy savings. It does not rely on ducting, furnaces, fans or blowers and therefore the system is virtually noiseless due to the lack of air movement.

Geothermal Radiant Hydronic Floor Heating Features:

Energy Efficient - The U.S. Environmental Protection Agency has rated it the most environmentally clean and efficient conditioning system. Read the full EPA report here.
Pleasant - Hydronic heating provides warmth the way nature does by natural convection and radiation and does not dry out the air
Safe - There is no danger of a burn or scald as the system is fully enclosed with radiator temperatures well below boiling point. The surface temperature of natural convectors is pleasantly warm to the touch.
Silent - Anyone used to the noise of wall heaters, space heaters and some fan forced ducted units will be amazed and delighted by the silence of hydronic heating.
Environmentally Friendly - Drawing heat from the earth itself, Direct Energy has chosen systems that deliver renewable geothermal energy with higher efficiency than any other powered water or associated heating system.

"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

"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

“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

"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

“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

ANNOUNCING THE 5X4 HAYES LANE PROJECT

Installation of GSHP cooling system for CSIRO's ASKAP for which the Prime Minister has awarded funding on 9 Jun 2010.

GSHP Installation for CSIRO’s ASKAP

2012 Australian Geothermal Energy Conference

Read the latest Report to the Council of Australian Governments’ Select Council on Climate Change. Chapter 2.4, p.22 demonstrates that GSHP is moving in the right direction !   Seventeen of the submissions to this paper supported the inclusion of GSHP in the RET scheme. Various submissions refer to the technology as ground source heat pumps, direct use geothermal heating and cooling systems. One of the primary reasons given for inclusion of this technology is that it is a form of heat pump, similar to air-sourced heat pumps that are already eligible under the RET, and utilises geothermal energy which is recognised as a renewable energy source under the RET scheme.

Critical Policy update - GSHP inclusion in RET

Government rebates for the installation of Geothermal Heating & Cooling are available in regional Victoria through the Four Seasons Energy Pilot Program. Feasibility studies: Funding will be provided for community groups, councils and businesses for feasibility studies into using these new energy technologies in comparison to other combined heating and cooling options.
