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.
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, (THE SANDEN DOES NOT PUT OUT 4.5kW IN LOW AMBIENT TEMPERATURES) working the Sandens far beyond their design capabilities, systems never working properly, and leading to premature failure of the heat-pumps.
Sanden heat-pumps are great 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.
For more information please >>contact Skyline Energy<<.
Changing from GAS/LPG to heatpump - for panel radiator systems ?
Heatpumps have lower water temperature than a gas boiler - but it still works!
The heat output of a panel radiator is based on the entering water temp, the room temperature, and the water flowrate or exiting water temperature.
Gas boilers can generally output water up to about 83C but to retain good efficiency we usually run our heatpumps to max of 55C. (the hotter we push the water the lower the efficiency)
Radiator manufacturers usually state the output of their radiators based on 80C entering temp, 60C exit temp, and 20C room temp.
At 55C/45C/20C for heatpump the panel radiator output would be roughly half.
Boilers modulate the gas flame, from max output to about 15% before turning off. They cycle on and off as required. When the house reaches the set temperature the system switches off until the temperature drops, then cycles back on usually at max flame before modulating.
What all this means is you can put a 30kW gas boiler on a 20kW heatload, it will quickly heat the water to its set temp (80C) then modulate, the water will be flowing through the rads at 80C and heat the house quickly up to temp, then cycle off.
(On most boilers you can program the water output temperature. If you can do this on yours, you could try turning it down to 55C and see how it performs)
Our heatpumps do not modulate but they do cycle on and off according to the house temp. If you change to a 55C heatpump it will take longer to heat the house because of the lower output of the panel radiators, but it will get there as long as the house does not lose heat faster than the panel radiators can heat it.
If the response from the heatpump is too slow, you could consider adding extra radiators where necessary.
Some heatpumps are advertised as hi-temperature heatpumps, but running them at 70C instead of 55C would drive down the efficiency to the extent that power usage would be far higher.

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 if you have the power to drive it, is an 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.
Air-sourced+Solar Electricity = lower initial cost and lower running cost than Geothermal
Skyline Energy Hydrocarbon Hydronic Heat Pumps:
Hydrocarbon vs conventional refrigerant:
Our considerable and comprehensive in-house research and development tests, backed by independant industry experts, have shown that the performance difference offered by hydrocarbons over conventional refrigerants can be up to about 20%, AND reduces wear and tear on the components!
- Perfect for Hydronic Heating
- 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 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.
All Skyline Energy Air Sourced Hydrocarbon Charged 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 even local voltage fluctuations.
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.

PLEASE CALL FOR FURTHER SIZING INFORMATION
Water-flow rate through the heat exchanger in the heatpump is critical to efficiency and usually higher than required through hydronics, so a buffertank is essential.
An appropriate capacity expansion tank, pressure relief valve etc is required on all pressurised hydronics systems.
Skyline Energy offer a range of high quality competatively priced hot water circulating pumps.
Skyline Energy Cold Climate heatpumps 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, Skyline Energy's unique Air Sourced, hydrocarbon charged, Ziehl-Abegg "owl" fan Heatpumps 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.
Do you want to lower your energy bills?
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.
Skyline energy installed our first heatpump hot water service in 2002. Since then we have installed thousands. We have not supplied any rooftop "solar" hot water systems for years!
3. >Home Heating< - Hydronic heating - Simply the best
Skyline Energy is the undisputed leader in the field of hydronic heating with heatpumps, and our continuous R&D program ensures we stay at the top. Let us exceed your expectations!
Solar Electricity with Battery Storage
Traditional solar inverter systems do not have capacity for *storage,so the excess solar energy you generate is lost back to the grid. With no stored electricity in reserve, when the sun goes down you have to sourcepower from the grid.
*(storage can be added later but a replacement or additional inverter will be required)
Redback inteligent inverters
Skyline Energy can offer you the state-of-the-art Redback "hybrid" Inverter masterminded by Australian solar experts! with >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 !
Redback inverters can also be coupled with a range of other battery technologies, such as LG Chem Lithium, Pylontech Lithium etc.
Redback have developed a matching battery storage cabinet to house Lithium batteries, with inbuilt cooling fan to keep batteries cool, and can be installed inside or outside.
The overall output of traditional, single-inverter type solar electricity systems can be compromised by partial shading and aging or underperforming of individual panels. The Tigo Optimizer maximises the output of each solar panel in your system.
This is done by making solar panels run independently of each other, so one panel is not dragged down by the shade, soiling or mismatch of the other panels.This increases the overall output of your solar system.
Safety is also increased, as the Tigo optimizer deactivates the panel in any unsafe situation.

Siddons Solarstream and other split-system heatpump replacements and new systems:
SX-02 and SX-03GT Hydrocarbon
SX-320 and SX-640GT Hydrocarbon
hot water heatpumps with patented
The Siddons Solarstream 327-SS, 264-SS, and 417-SM heatpumps were amongst the most successful hot water units in Australia.
Skyline Energy was one of the first Siddons dealerships, and we supplied our first Siddons Solarstream heatpump in March 2006. Since then thousands have been sold.
Siddons Solarstream stopped manufacturing them about 4 years ago.
The "Everlast" 316 stainless steel tanks they used are almost indestructable but some of those heatpumps are getting a bit tired now, so Skyline Energy now offer new, "improved" replacements for those old heatpumps - >SX-02< Hydrocarbon replacements, and >SX-03GT< Hydrocarbon units with more powerful compressor.
The performance difference offered by hydrocarbons over conventional refrigerants can be up to about 20%, AND reduces wear and tear on the components!
We will also be releasing a 320Lt >SX-320< Hydrocarbon and 640Lt >SX-640GT< Hydrocarbon complete hot water systems.
These new systems have Stainless Steel inner tanks like the old Siddons, with a new patented micro-channel condenser clamped around the tank, and of course the benefits of the hydrocarbon heatpumps.
