Geothermal heatpump systems are only slightly more efficient, but offer a vastly reduced return on investment compared to our Air-Sourced hydrocarbon heatpumps. Combine air-sourced hydrocarbon heatpump with solar electricity for the ultimate in hydronic heating efficiency.
We also introduced inverter-style heatpumps but were disappointed with the results, they were not as efficient as our ZA hydrocarbon heatpumps, so we have discontinued development.
Hydronic Heating systems - Never be cold again
If you've ever experienced the luxury of a heated floor, or stepping from the shower into a warm towel, on a cold winters day, you'll know why Hydronic Heating systems are becoming very popular.
There are no drafts from forced air movement, you are just gently bathed in a warm environment. It's safe for all the family and great for people with allergies.
Water can be heated by GAS, LPG, Wood,
(Geothermal) Heat Pump, Water-Sourced, Air Sourced
Heat Pump, or even a combination of one or more of these.
For Australian conditions outside of natural GAS area's,
we generally recommend Air Sourced Heat Pumps as they
provide the greatest overall control, sustainability
and cost efficiency compared to straight LPG, Wood,
and electric systems.
We use the trusted name in
non GAS hydronics throughout Australia, and despite
what you may have heard can efficiently heat
water hot enough for hydronic heating *radiators and
towel rails! (Increase the radiator size to compensate for lower water temp)
Heat-pump running cost less than GAS and far less than Electric or LPG
Electricity AND GAS prices are constantly rising, and solar electricity costs continue to fall, so although installing an air-sourced electric heat-pump will cost more initially, there will be significant cost savings over time.
There are lots of factors that affect
the COP of a heat-pump under the required conditions:
- The design and innovation of the heatpump - they vary greatly!
- The gas/refrigerant used
- The ambient air temperature
- The starting or returning water temperature
- The water flow rate
- Local voltage fluctuation
- The input kW will also vary with the other variables
There is no such thing as "over-unity", energy in must equal energy out. The MAGIC is where the energy-in comes from and how efficiently it can be harnessed.
The Coefficient of Performance (COP) is simply a way
of measuring the efficiency of something. It is the
ratio of energy in vs energy out. A COP
of 3 means 3x units of energy out for 1x unit in. In
our case with air-to-water heat-pumps, the difference
in the numbers is the energy harnessed from the air
- at COP=3, 3kW of heat energy out comes from 1kW of electricity in, and 2kW of "solar" (heat) energy in, from the air.

Sanden Heat-pump Hydronics ?
Were you sold a Sanden heat-pump system for hydronics?
We have been contacted numerous times by customers who were ill-advised and were sold hydronics systems running from multiple Sanden Heat-pumps. (not by us) Unfortunately, most of these systems were undersized, working the Sandens far beyond their design capabilities, systems never working properly, and leading to premature failure of the heat-pumps.
Sanden heat-pumps were, and still ARE the best heat-pumps for potable hot water, and if they had been sized correctly may have coped as hydronic heat-pumps even though that was never their intended application.
If you are such a customer, we can help you try correct the situation, and replace the Sandens with an adequately sized Skyline Energy hydronic heatpump. You may be able to re-use the tank and one of the heat-pumps for dedicated potable hot water, and recoup some of the original cost of the other heat-pumps.

Simplified rules for sizing your heatpump for . . . . .
MAXIMUM EFFICIENCY AND SERVICE LIFE!
- Calculate how many kW are required
- Look at the climatology of the location to establish the duration of 0oC to +4oC. Donít just look at the extreme temps, look at the mean overnight temp and duration
- If the ambient air temp rarely dips below +4oC or does so for short periods then you can use this simple calculation...
3.3x electricity input kW = heatpump output (ZA hydrocarbon models) kW to size the heatpump.
- If the mean overnight ambient air temp is between 0oC and +4oC change the calculation to
2.5 x electricity input kW = heatpump output (ZA hydrocarbon models) kW to size the heatpump.
- A more powerful heatpump will raise the water temp more rapidly so it will cycle off before it needs to defrost,
thereby maintaining a higher COP and efficiency.
- If your building has very poor thermal efficiency (leaks heat energy) this will lead to longer running time increasing the likely need for defrosting which leads to higher running cost.
- Skyline Energy Hydrocarbon heatpumps do not modulate output like gas boilers, so it is also important not to oversize which will cause short-cycling. Generally it is not necessary to increase the water storage capacity beyond 100Lt to 400Lt. (greater water storage can work against you in the shoulder periods where heating may not be required for more than a few days, as you need to reheat ALL the water in order to be able to use it)

Home Heating with Radiant Floor Heat vs Forced Air
Why is radiant floor heat better than forced air heat (ducted/aircon)?
It is more comfortable, more energy efficient, provides a healthier environment and is more aesthetically pleasing.
Radiant Heating is Comfortable Heating!
Comfort is hard to define and is best understood as the absence of discomfort. Perhaps the most remarkable thing about radiant floor heat is what you won't notice. There are no forced air registers to see. No noise or dust from mechanical blowers. No hot air blowing on you. No hot air collecting at the ceiling, wasting energy. No cold floors to chill your feet. The mild warmth of a radiant floor is a subtle experience and always feels just right
Radiant Floor Heat Saves Energy
It takes less energy to heat a home with radiant floor heating than a forced air system
Radiant Heat is Healthy Heat
Forced air systems not only blow hot air, they also push allergens, dust and other airborne particles around your home. Improved indoor air quality can reduce allergies, medical bills, incidences of asthma and more. European studies indicate that dust mite populations are reduced as much as 90% in radiant heated homes. A quiet, peaceful environment, devoid of noisy fans and blowers, is a healthier and more relaxing environment too.
A Message to builders and owner-builders in VIC:
Depending on your location, we may be able to offer you additional services including general plumbing and general electrical contracting for all of your home-building/renovating requirements.
We supply and install hydronic heating systems and heatpump hot water systems in many areas:
Warning: Never buy a heat-pump that has an electric element - check first!
Hydronics and potable hot water (2-in-1 & 3-in-1) Heat Pump Systems
Hydronic Heating - Potable hot water heating - AND Refrigerated
Air-Conditioning (Cooling) all from the same unit,
sounds too good to be true . . . maybe it is!
Sizing a heat-pump to do hydronic heating AND potable hot water means increasing the size of the heat-pump to cater for both applications without compromising either one, and increasing the complexity of the system. We think its false economy, and recommend seperate potable hot water unit using either a Solar-Boosted GAS, or high efficiency heat pump
elements totally destroy the efficiency of a heat pump. To
make-up for an undersized heat pump, AND to maintain
the potable hot water temperature, some combined units
can use up to 3x 3kW electric elements for heating!
Efficient back-up for solar and/or wood/pellet-fired hydronic system:
Heat Pump Solar or Wood Boiler back-up System
Instead of the traditional electric element backup,
why not use a heat-pump that will provide the same (or
more) energy but consume 60-70% less electricty!
How does this work
The solar and/or wood boiler system heats water in
a storage tank which supplies the hydronic panels or
floorcoils with hot water. When the sun/fire dies down
and the water starts to cool, and if the hydronics needs
more heat, the control system will fire-up the heat-pump
to replace the heat from the solar/fire. Once the water
in the tank reaches its optimum temperature, (with or
without a rekindled fire) the heat-pump is automaticay
Best of both worlds
Sizing the heat Pump depends on whether you want just
boosting, (a small heat pump like the SX-10) or a heat
pump that gives you the flexibility to use either wood
or dedicated heat pump whenever you want. We can help
you which air-sourced heat pump booster is right for
your requirements - Call 1300 552 976 or email:
Heat Pump Hydronic heating systems are:
- Efficient (absorb solar energy)
- Low maintenance
Although heatpumps use electricity, and we've all been led to shudder at the talk of using more electricity, heatpumps are a very efficient use of electricity used to harness heat from the air - the most abundant energy resource we have!
Depending on your location, you can expect an average efficiency of about 300% (in colder climates) to over 400% (in warmer climates) from your air-sourced hydronic heatpump.
You can even offset some of the electricity needed, with Solar Electricty, and we can install your solar electricity system in conjunction with your heating system.
If you want to use your heat-pump/boiler to heat your pool as well as your house, you will need an >external heat exchanger <
We offer a range of "shell and tube" heat-exchangers in two types, Titanium heat-exchangers and 316 Grade Stainless Steel heat-exchangers. (also suitable for a wide range of other commercial/industrial applications)

The best just got better - > Sanden ECO "PLUS" < (NEW MODEL) Air Sourced Heat Pump
The solar hot water systems we're all used to seeing on the roof, are not always the best environmental solution!
The Sanden ECO "PLUS" heat pumps are whisper quiet & extremely efficient, using a small amount of energy to collect the abundant heat that the sun puts into the air we breathe, and may be the overall best system for your specific situation. Industry leading performance means higher rebates are available for our heat pumps.
- New "PLUS" model is more efficient and now has 6yrs warranty on the heatpump
According to a >case study< of a suburban Melbourne home, conducted by Bruce Rowse (M.AIRAH) and printed in the AIRAH Feb 2017 Journal,
a >Sanden ECO Heatpump hot water unit"uses one-fifth the energy of a gas hot water service" , , ,
"This is just 19% of the expected energy consumption of a 6 star gas hot water heater"

Why we don't recommend Solar Boosted Electric systems:
Victoria State Government homeowner guide to sustainability (PDF) page 4, table 1.1, supports our claim that heat-pumps can have a significantly lower lifecycle carbon footprint than solar-boosted electric systems:
- avge heat pump produces 23 tonnes CO2 emissions
- avge solar-boosted electric produces 33 tonnes CO2 emissions

heat-pump water heater on the ground - higher return
on investment than electric solar hot water systems.
In other areas results
may vary, but in almost all conditions, our heat-pumps
will outperform other heat-pumps and solar boosted electric systems.
Conventional Solar-Boosted Electric Hot Water systems actually rely on inefficient Electric-Element boosters - especially when you need it most IN WINTER!
The new and improved Sanden ECO "PLUS" heat pump will:
You don't have to worry about leaving the booster off - there isn't one.
- NOT put you at risk
- ensure your water ALWAYS reaches and maintains safe temperature
- kill or prevent harmful bacteria
- save you money
- innovative plumbing configuration provides hot water 50% faster than most other heatpumps

Solar technology continues to leap forward with inteligent inverters that "learn" your power usage patterns and self adjust to maximise the benefits from battery systems, they even use your internet connection to access weather forecasts to predict solar yield and decide whether to charge from low-cost off-peak/time-of-use tarifs - its all about maximising solar self-consumption. We've have done the training and have the expertise to advise which system is right for you, and all you need to do is enjoy the results from the system.
Redback Hybrid Inverters, solar optimsers, and battery systems
We can offer you Redback "hybrid" single and 3ph Inverters (masterminded by Australian solar experts!) with
>Pylontech, LG Chem, and other Lithium Battery Technology<
Inteligent technology that gives you the power to store, monitor and manage your home’s solar energy all in a compact, elegantly design unit mounted either inside or outside your home. You can also upgrade your existing solar system !
With Solar Optimsers like Tigo and Solar Edge - add Micro-Inverter-Style benefits to standard/single-inverter system, to maximise the returns from your solar panels by allowing each panel to work independantly, harnessing and sending it's full potential output to the inverter.
With single/standard inverters, all of the panels outputs are reduced to match the lowest performing panel in the "string". Individual panel outputs do vary and degenerate with age, so if you have say 10 panels and one of them is "sick" or otherwise underperforming, it will cause the output of all the other panels to reduce to its level, and you may not even be aware of it. Even with monitoring, you can only tell what the entire system is producing.
