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.

Heating your home with panel radiators/convectors

Hydronic Central heating
If designed, installed and used correctly, hydronic central heating can be economical and highly effective in most homes. (Skyline Energy can provide you with a no-obligation quote for a heating system designed for your home)

Water is heated, and then pumped through piping to panel radiators or convectors positioned in each room. Heat is transferred directly from these to the room air.

Benefits include:

  • Manual or automatic control valves to each panel allow individual rooms or zones* to be heated independantly
  • Panel radiators provide effective heating for rooms with high or low ceilings
  • Response time is generally good, and you should start to feel a difference within 30 minutes.
  • Low maintenance requirements.
  • The proven effectiveness of central heating - widely used in Europe for almost a century.

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

Air Sourced Hydronic Heat Pump PLUS Solar Electricty - . . . . SMART MOVE!

 

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.

Radiators

Radiators are sized based on the area to be heated, and the temperature of the water fed to the radiators.
Traditionally, using GAS or Oil burners generated very hot water, maybe 85oC+ but being more "health and safety" conscious - systems are being designed for 60oC water temp. To compensate for the lower water temperature, the radiator size is increased. This adds very little to the overall cost installed cost.

  • Supplied and installed using a GAS boiler at 85oC+, would be from about $1800 per radiator
  • Supplied and installed using a GAS boiler at 60oC, would be from about $2100 per radiator
  • Supplied and installed using an air-sourced heat-pump at 55oC, would be from about $2500 per radiator

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 over 100kw 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!

For existing homes with radiators sized for GAS/LPG/Wood boilers and water temperatures above 60C, we CAN supply high-temperature 75C heat-pumps, but running a heat-pump at these temps is less efficient than running at 55C-60C. Please ask for more details on High Temperature hydronic heat-pumps.

standard radiator Hydronic central heating is:
  • Safe - There is no danger of 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.
  • Efficient - Our "New-Age" heat-pump systems require minimal energy to maintain a comfortable temperature.
  • Quiet - Natural air flow will caress your body with warmth,




Home heating with water filled radiators

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 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 Skyline Energy Air Sourced Cold Climate 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

domestic slab heater

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

  • Cheap to buy, reasonable cost to run etc. etc. (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



Heat-Pump 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 too!

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.  

The completed system is comprised of:

  • Radiators & towel rails
    (optional thermostatic valve heads for local
      temperature control)
  • 1 or more Hydronic Hydrocarbon Heatpump Units
    Recommend the Zeihl-Abegg fan models
    for highest efficency and lowest sound-level
  • Water flow & return lines
  • Buffer Tank & expansion sub-system
  • Recirculating pumps
  • 1 or more wall mounted room thermostat
    (Heating zone temperature control)
  • Can be offset by Solar Electricity system

Skyline Energy V25ZA Hydronic Heatpump langdons Hill

We create a primary circuit through the heat-pump and buffertank, and secondary circuit through the buffertank and radiators

Skyline Energy Cold Climate Hydronic 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
  • Various sized units from 10kW to 200kW output
  • We do NOT recommend using under- capacity heat-pumps boosted by LPG/GAS/electric elements - (lowers overall efficiency)
  • 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
  • A geothermal heat-pump costs about the same as an air sourced heat-pump, but you have to add the substantial cost of groundworks. (Put the extra towards Solar Electricity instead!)
  • Although an LPG boiler is about the same cost of a natgas boiler - forget it! the running cost is too high - use Heat-Pump (only use LPG if mains power is not available)

How does it work?

Our air-sourced hydronic heat-pump water heaters operate on a similar principle as a refrigerator or reverse-cycle air-conditioner.

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: . . . .
