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

Energy costs are at an all-time high and still rising. So, 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 air sourced 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.

With our optional external heat exchanger units you can also heat your swimming pool using the same heat pump.

Concrete Slab Hydronic Heating Systems

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 air sourced heatpump!

Slab Heater

In Screed Hydronic Heating System

In Screed Hydronic Floor Heating Systems

An in screed hydronic floor heating system is similar to the slab heating system, and is usually used to provide floor heating over an existing floor. An in screed system is usually not *structural so can be thinner than a typical slab, and therefore there is less mass to heat so it heats-up quicker and cools down quicker than a slab system.

To make the system even more efficient we offer a pre-formed panel insulation system that can be laid over the structural floor and the floorcoils can be easily laid into the pre-formed guides and clipped where necessary. *A layer of light mesh is usually laid over the floorcoils. This heating system reacts very quickly by comparison.

Other components of the screed system are the same as for the structural slab heating system above.

Geothermal or Air Sourced Heat Pump ?

Easy! Use an Air Sourced Heat Pump!
Invest the GEOTHERMAL groundworks money into solar electricity and get a much better return on investment, and a much more environmentally sound system!

A GEOTHERMAL heat-pump costs about the same as a Cold Climate Air Sourced heat-pump, but you have to add the substantial cost of groundworks . . . .

Instead, use a Skyline Energy SM-xxx model Air Sourced Heat Pump and invest some of that money saved into Solar Electricty for a much higher return on your investment.

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
  • 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!

Hydronic Slab Water Heaters

Geothermal

You may hear a lot of good things about Geothermal Energy - don't confuse this with domestic geothermal hydronic heating systems - they are usually talking about specific commercial-scale projects accessing underground special hotspots, not your backyard!.

Generally, 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 significant cost of burying or drilling 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) If you spent some of the Geothermal Groundworks dollars on Solar Electricity, you could have an air-sourced hydronic heating system 100% offset with solar electricity - with spare solar electricity to run your aircon/cooling system for free too!


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)
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 normal winter conditions, a Cold Climate Hydronics heat-pump will use less energy than the booster required in a solar-boosted GAS/LPG/Electric 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.
(Natural GAS is NOT a renewable resource and still causes greenhouse gas emissions when burned, but at the moment it's cheap. The electricity used by heat-pumps can be supplied by 100% clean renewable energy systems . . . . )

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

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

  • In summer, solar systems can provide 100% of the energy required for domestic potable hot water
  • In winter and in the colder climates solar systems 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, Solar systems (incl 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 far less power than the booster required in a wood/solar 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, reasonable cost to run (at the moment . . .) - would recommend Condensing Boiler option
  • 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

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.

Our unique Cold Climate Air Sourced Hydronic Heat Pump technology has a vast potential for harnessing renewable energy and reducing energy consumption. Our heat pumps are able to extract heat from the air and concentrate it to provide hot water for heating homes and commercial buildings. The only energy required is that which is used to concentrate the thermal energy - so the system can provide a heat output up to four times larger than the energy input.

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 would have given up and reverted to its 'booster', our air sourced hydronic heat pump is still absorbing vast amounts of solar energy.

Unlike much of Europe where hydronic heating has been used for decades, in most area's of Australia a Cold Climate Air Sourced heat pump, used in conjunction with Solar Electricity will outperform a ground sourced (Geothermal) heat pump, at a much lower overall installation cost, and there is no need bury hundreds of metres of pipes in the paddock.

With zoning control and even remote activation by telephone if required, used in conjunction with good building practices such as good insulation, passive solar design, hydronic heating with our state of the art, correctly sized heat pumps can be an economical and ecological, wise investment for your home heating requirements.

During the life of this product, electricity will be generated more & more from renewable resources, making it the energy of choice: . . . . “let us exceed your expectations”
