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 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,
whilst also combatting the adverse effects on the environment by reducing
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.
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.
With our optional twin heat exchanger units you can also heat your swimming pool using the same heat pump.
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!

How much does it cost?
Skyline Energy generally supply hydronics components such as Cold Climate Air Sourced Heat Pumps to builders and trade contractors, however we can provide a full design and installation service. (depending on actual location)
Generally, the larger the project the lower the overall cost per square meter.
- Floorcoils can cost on average anywhere from $45 to $50 per sqm, supplied & installed
Water Heaters (boilers)
don't recommend using traditional solar or evacuated
tube boosters, as these provide the least input when
- A natural gas boiler for up to 250sqm slab is approx.
$2500 plus delivery & installation

- 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
- 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!

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 an Air Sourced Heat Pump and invest some of that money saved into Solar Electricty for a much higher return on your investment.

Hydronic Slab Water Heaters
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!
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 gase emissions when burned, but at the moment it's very 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 less power than the booster required in a solar or 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
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

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.
The system is comprised of:
- Floorcoils laid in the slab to 1 or more manifolds
- Flow & return lines to/from manifolds
- Heat-pumps with co-axial heat exchanger
- Buffer Tank & expansion sub-system
- Recirculating pumps
- Wall mounted thermostat (Zone control)
Our range of sensational air-souced hydronic heat-pumps are rated from 10kw to 200kw output.
These "21st Century" Hydronic Slab Water Heaters are unlike any other, because:
- They have sensationally low running costs
- They can keep your home warm all winter regardless of weather
- They are very durable and robust
- Multiple units can heat any sized slab
- We do not recommend under- capacity units boosted by GAS/LPG/electric elements
- Almost as efficient as Geothermal heat-pumps, but much cheaper to install
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, reducing energy consumption and emissions. Our heat pump is 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. Running costs are similar to Natural GAS Boilers, however in non-GAS areas it can potentially reduce heating costs by more than 75% compared to other fuels like LPG and straight electricity.
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 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 way outperform a ground sourced heat pump, and generally 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”
Using the Sustainability Vic target 12% green power figure of 1.093kg CO2/kwh, and the solar contribution
for our heat-pump under melbourne conditions (67%), it will produce 4% less CO2 than gas.
