Welcome, to a Warm, Comfortable, Energy Saving Home . . .

It's not good news for any of us that home energy costs are at an all time high and with soaring GAS prices, what can we do about it? These pages will give you an insight into our range of energy efficient solutions which could save you many hundreds of dollars each year.

Studies have shown that in-slab heating provides a most enjoyable warming experience!

Heating a concrete slab from cold takes a relatively long time, at least several hours, but once at operating temperature, it will radiate heat consistently. For this reason, in-slab heating is generally best suited to buildings with permanent or high occupancy.

Slab Heater

Efficient, Luxurious, Simple:

Used in conjunction with our solar heat-pump water heaters, home heating with hydronic (water-filled) heating coils in the slab provides luxurious comfort.

Hydronic Floor heating pipes are laid throughout the concrete slab in loops or 'coils', during construction. Each coil can be controlled independently to heat only the area(s) required. (Groups of coils can be managed as one 'Zone' and controlled typically by room thermostat)

Warm water is circulated through the system of pipe work, the floor is heated and radiates warmth throughout the house.

Watch "Benefits of Radiant Floor Heating" on youtube

Concrete Slab - Heating System

The completed slab heating system is comprised of:

  • Pipes coiled in the slab (usually 1 "coil" per 20sqm)
  • Each Coil has a shutoff valve (usually 1 or more manifolds located in cupboards)
  • Room thermostat for general temperature control
  • Flow & return lines and recirculating pump
  • A buffer tank is usually required
  • Various bits'n'pieces (plumbing)
  • Timer, switches/breakers etc (electrical)
  • . . and of course water heater!

Slab Heater

How much does it cost?

Generally, the larger the project the lower the overall cost per square meter.

Floorcoils

  • Floorcoils and manifolds can cost on average from $45 to $50 per sqm, supplied & installed

General advice

  • We do NOT recommend using under-capacity Heat-Pumps boosted by GAS/LPG/electric elements, as these "HYBRID" systems may considerably reduce efficiency and increase running costs, instead use the correct sized heat-pump from our extensive range (up to 200kw output)
  • We do not recommend using multiple domestic-type storage tank heat-pumps for hydronics, as these work best with fairly static water - hydronics requires continuous water flow, better suited to co-axial heat exchangers which are more efficient
  • We DO recommend using Solar Electricty to offset heat-pump use!
  • Although an LPG boiler is about the same cost as a natural gas boiler - the LPG operating cost is too high - use air-sourced Heat-Pump (only use LPG if no mains electricity, but beware!

why we don't use solar tubes why we don't use solar tubes

THEY DON'T WORK WELL ENOUGH IN WINTER!

 

Ask this question of your Solar Hydronics supplier:
Over the heating season, what percentage of the total energy will come from the Solar, and how much from the "back-up" heater ?

For most homes, solar is just not a cost-efficient option for hydronic heating, typically providing only about 20% of the energy required. (unless you have massive water storage - thousands of litres in insulated tanks, to collect and store lots of energy when it available, and deliver it over winter)


In normal winter conditions, a Cold Climate Hydronics heat-pump will use less energy than the booster required in a solar-boosted hydronics system. If you are in a natural gas area, you'll probably just use a straight gas boiler, if no gas use a correctly sized hydronic heat-pump.

We recommend Air-Sourced heat-pumps over Solar and Geothermal heaters, WHY?
click here for a more detailed explanation.

If you don't have adequate power supply for the required heat-pump, only then would you choose an LPG boiler.

Note: The only other exception to this would be if the energy harnessed over summer could be fully utilised for a secondary purpose such as Pool heating. The additional cost of including a solar tube array system may then be justified.

  • In summer, evacuated tube systems can provide 100% of the energy required for domestic potable hot water
  • In winter and in the colder climates they will need to run their boosters to ensure a safe water temperature.
  • In the Southern States, home heating in winter requires far more energy than potable hot water.

In the Southern States where winter heating is a necessity, evacuated tubes just do not provide enough energy when needed most, and for most home installations, can therefore at best only provide a token input.

  • If you are in a natural gas area, you'll probably just use a straight gas boiler, if no gas use a heat-pump.
  • In normal winter conditions, a heat-pump will use less power than the booster required in an evacuated tube hydronics system.
  • If you don't have adequate power supply for the required heat-pump, only then would you choose an LPG boiler.

Natural GAS Boiler

domestic slab heater

Nothing to get excited about here, its just a GAS boiler!

  • Cheap to buy, cheap to run etc. etc.
  • Combo models available for domestic hot water AND hydronics in single unit
  • Available in various sizes to suit system demand
  • LPG models also available - but LPG is VERY expensive to run - recommend using air-sourced heat-pump if adequate electricity supply available


creating emissions Burning firewood or GAS releases heat up the flue into the atmosphere, an air-sourced heat pump recycles heat from the air into water for your benefit

Heat-Pump Water Heaters:

Geothermal
Below ground, the temperature doesn't fluctuate as much as above ground. We can take advantage of that by burying pipes underground to extract heat. Generally, the deeper you go the ground gets warmer. The problem with Geothermal systems is that the cost of burying the pipes far outweighs the operating cost savings compared to an air-sourced heat-pump. (you will never save enough in lower operating costs, when compared to the installed cost of an air-sourced system)

Air-Sourced
HEATING THE NATURAL WAY: An air-sourced hydronic heat pump uniquely extracts solar heat energy found abundant in the in air and transfers it to water.  

Skyline Energy SX-24 air sourced hydronic heatpump

The air-sourced system is comprised of:

  • Floorcoils laid in the slab to 1 or more manifolds
  • Flow & return lines to/from manifolds
  • 1 or more Air Sourced Heatpump Units
  • Buffer Tanks & expansion sub-system
  • Recirculating pumps
  • Wall mounted thermostat (Zone control)

An Ecological Solution:

The mysterious heat pump.
At first, our claims about this being a high efficiency solar system may seem outrageous, but really its quite simple - there is no magic, just science. Pushing refrigerant through a massive heat-exchanger at about -30oC, it readily absorbs solar energy in the form of heat out the air. Because they don’t rely on direct sunlight radiation, they can operate in all seasons of the year, under all conditions; shade, overcast, sun, rain, frost, even at night.

Long after a conventional solar collector array or evacuated tube system has given up and reverted to its booster, our air-sourced heat pump is still absorbing vast amounts of solar energy.

Geothermal systems provide the most efficient heating, however - unlike much of Europe where hydronic heating has been used for decades, in most area’s of Australia an air-sourced heat pump will provide similar performance to a ground sourced (Geothermal) heat pump, but there is no need bury hundreds of metres of pipes in the paddock at great expense!

With zoning control and even remote activation by telephone if required, used in conjunction with good building practices such as good insulation, hydronic heating with our state of the art, correctly sized air-sourced heat pumps can be an economical and ecological solution to your home heating requirements

During the life of this product, electricity will continue to be generated more & more from renewable resources, making electricity the fuel of choice.
