Skyline Energy Air Sourced Heat Pumps for Hydronic Heating
Simply a very efficient way to heat your home
- No inefficient back-up element required
- Copeland Scroll compressors
- Automatic defrost
- Easy installation
- You can depend on our 15yrs+ experience
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. Don’t 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 x electricity input kW = heatpump output heat kW to size the heatpump.
- If the mean overnight ambient air temp is between 0oC and +4oC change the calculation to
2 x electricity input kW = heatpump output heat kW to size the heatpump.
Now there is a trick here, it's not that the COP and efficiency is going to suddenly crash, but 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.
- produce supply and install Heatpumps specifically tuned for Hydronic Heating
- design and supply complete hydronic heating kits for plumbers to install
- can design, supply and arrange installation of hydronic heating in some areas
- installed our first air sourced heatpump in 2002
- installed our first hydronic heatpump system in 2005

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.
Says Tony Regan - business development manager for LNG for Asia Pacific at energy analysts and consultancy Platts
>Gas, now off the agenda . . . <
for any project pursuing the most sustainable practice. Hot water, cooking, the lot – but replaced with what?
The drivers for change? Technology and economics have moved on dramatically in the last couple of years. Solar power is now so cheap, and heat pumps and induction cooking so efficient, it actually makes more economic sense to get back to the old 60’s saying “Live better electrically”. There are various ways of setting this up, with or without generous feed-in tariffs.
The best method is to align most of the building’s loads with the peak solar (PV) productive hours. For example, an efficient heat pump, with a coefficient of performance of 4 or better (CoP = units of heat produced for every unit of energy consumed), can heat a 315L tank in a few hours, in winter. This is stored for later use either as potable hot water, or for hydronic heating, or both. Hydronic heating has no equal in the pleasant radiant heat it imparts to occupants. The cost of a combination hot water and hydronic heat pump system has almost halved by using PV powered heat pumps instead of solar-gas systems. And they can achieve zero emissions, with zero running costs. Envirotecture
". . . connecting a new or existing home to the mains gas network today is now the most expensive long-term energy supply option"
". . . As gas becomes increasingly a discretionary fuel, will the gas networks go into a ‘death spiral’ causing asset writedowns and leaving more costs to be recovered from disadvantaged consumers?"
Alternative Technology Association
Can I go GAS now and upgrade to heatpump later, or upgrade existing GAS to heatpump?
simply Yes for slab heating.
Yes conditional for panel radiator heating. Size the panels for 50C water temp - this will mean bigger panels, but not much extra cost. For existing panel radiator systems, turn down your boiler to about 50C -55C if the panels provide enough heat then yes we can do an upgrade.

Skyline Energy - Experts in efficiently heating water:
Don't kid yourself!
We see all sorts of ideas and formulas typically on forums about heating homes with solar tubes and fancy tanks, but in the end we see disappointing systems that don't do what they are supposed to do - keep you warm in winter!
Be realistic right from the outset, it takes a lot of energy to keep a house warm, and if you are worried about the initial heating system costs and ongoing running costs BUILD/MOVE TO A SMALLER HOUSE . . . .
We research and offer the most cost-efficient water heaters for winter hydronic heating.
Natural GAS prices are set for drastic increase
If you don't have Natural GAS or don't want to use Natural GAS, the optimum system is a single, appropriately sized, dedicated Air-Sourced Heat-Pump! - Add solar electricity if you can. You can forget Geothermal systems unless you want bragging rights on how much money you wasted.
Skyline Energy Dedicated Air-Sourced Hydronic Heat Pumps:
Hydrocarbon vs conventional refrigerant:
Hydrocarbon heat-pumps are being heralded as "Heating reinvented" . . . Our considerable and comprehensive in-house research and development tests have shown that the performance difference offered by hydrocarbon gas over conventional refrigerants is minor, non-linear under variable conditions, but can be up to about 10%, but 10% IS 10% and therefore we offer hydrocarbon systems too!

- High Efficiency
'Solar' Hot Water
- Can be offset
with Solar Electricity
- Can be the
back-up for wood-boiler instead of an element
- Can replace
a poor-performing solar-hybrid hydronics heater
- Can replace
an expensive to run LPG hydronics boiler
Hydronic Heating systems - Never be cold again
If you've ever experienced the luxury of a heated floorslab, 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 we generally recommend Air Sourced Heat Pumps as they
provide the greatest overall control, sustainability
and cost efficiency compared to straight GAS, LPG, Wood,
and electric systems.
Skyline Energy pioneered the use of air sourced heat pumps
for hydronic heating and continue to lead the field. Although our research shows that Evacuated Tube Solar provide very little additional heat for hydronics use, we will integrate them if you already have them!
Heat-pump still less than 50% of LPG running cost
Even though electricity costs have risen sharply in the last 12 months, a heat-pump running cost is still less than half the cost of using LPG (which along with Natural GAS prices, will also rise faster and higher over the next few years!) and about 1/3rd the cost of running straight electric heaters.
Electric heater = 1:1 Winter only Hydronic Heat-Pump typically = 1:3 (average)
Electric heater = 1:1 Potable water all-yr-round Heat-Pump typically = 1:4 (average)
Electric heater = 1:1 Summer only Pool Heat-Pump typically = 1:5 (average)
There are lots of factors that affect
the COP of a heat-pump:
- The ambient air temperature
- The starting or returning water temperature
- The gas/refrigerant used
- The water flow rate
- 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.
All Skyline Energy Air Sourced Hydronic Heatpumps are fine-tuned individually for MAXIMUM C.O.P. efficiency!
Why don't we state the output in kW ?
The kW output of ALL air-sourced heatpumps is a variable. It would be misleading to state the kW output without listing all the other variables, input kW (itself a variable!), returning water temperature, ambient air temperature, water flow rate, refrigerant type and charge.
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)
If you are completely off-grid, AND/OR you:
- Have access to about 4000Lt of waste oil per year,
- and, you don't mind getting your hands dirty
Then perhaps a waste oil burner for hydronics could be a good alternative solution for you.
Current technology waste oil burners are surprisingly environmentally friendly, but they do require maintenance involving cleaning etc. and handling of the waste oil, so they are not for everybody - ideal for a technically minded user like a car mechanic, tradesman etc.
They typically use about 3 to 4 litres of oil per hour.

Skyline Energy Cold Climate model air sourced heat pumps are the trusted name in hydronics throughout Australia, and despite what you may have heard can efficiently heat water hot enough for hydronic heating radiators and towel rails!
With predictions of sharply rising electricity AND GAS prices, Air Sourced Heat Pumps AND Solar Electricty offer the most cost-efficient long-term solution.
Some want a wood-fired hydronic system:
Heat Pump 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 wood boiler system heats water in a storage tank
which supplies the hydronic panels or floorcoils with
hot water. When the 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 fire. Once the water in the tank reaches its
optimum temperature, (with or without a rekindled fire)
the heat-pump is automaticay switched off.
Best of both worlds
Sizing the heat Pump depends on whether you want just
boosting, (a small heat pump like the SX-07) or a heat
pump that gives you the flexibility to use either wood
or dedicated heat pump whenever you want.
