• Running costs can be further offset with Solar Electricity

Our V35ZA Hydronics Heat Pump is not an "off-the-shelf" import, it is unique and purpose-built to heat water for hydronic heating systems. The cabinet and refrigeration system is pre-assembled to our design. We finish them locally, fit compressors and complete the refrigeration system, fit primary circulation pump, fit Acoustiblok and other proprietry sound-reducing tech, charge them with Hydrocarbons, install control systems, fine-tune and put each heat pump through quality assurance testing.

Over the years we have developed our own inhouse heatpump tuning/monitoring rig.
Every machine that leaves our factory has been fine-tuned for its application, has been "run-in" for hours, and is shipped with its own performance guarantee. When it is delivered and installed, it will work faultlessly from day one.

All air-sourced heatpumps lose efficiency the hotter the water temp so we generally set our heatpumps to 45^oC for slab heating, or 55^oC for radiator heating (recommend design for 55^oC inlet water temp for new radiator installations)

The dual compressor V35ZA can be spanned across 2 phases if you have 2 phase supply, or across 2phases of a 3ph supply.

We use Ziehl Abegg Hi-Tech Low Noise Owlet axial fans-for improved airflow and up to 15% higher fan efficiency. Acoustiblok ™, plus in-house noise-reduction technology, and installation techniques ensure lowest possible sound output level.

NOTE:
From July 2018 all V35ZA heatpumps will have a GPD25-16 primary circulation pump fitted internally.
For installation with a remote buffertank, a booster circulation pump may be required to achieve recommended water flow-rate.

We use Natural Organic hydrocarbons:

Our hydronic heat pumps use hydrocarbons instead of traditional fluorocarbon refrigerant.
When switching from fluorocarbons - R22, R410A, R502, R407C, R404A, etc., power bills can be dramatically reduced, and the wear and tear on the refrigeration system can also be minimised.

More efficient and economical:
The superior efficiency of naturally occurring hydrocarbon gases, which are purified and precision blended, combined with reduced charge weight results in great cost savings and on-going electricity savings for the user. Hydrocarbon refrigerants are 50% more efficient conductors of heat than fluorocarbon refrigerants, and their operating pressures are about 20% lower. These lower operating discharge pressures reduce the work that the compressor has to do thus reducing wear and tear. There is less pressure on pipework, joints, hoses, fittings and the like thus reducing the likelihood of leaks. This can and will extend the working life of your equipment.

Lower power input - lower power output?
Although our hydrocarbon heatpumps draw less power in operation than if we charge them with fluorocarbons, they also output less power at the top-end, but the magic is in the efficiency, much less power draw but only slightly less output power at the top-end
All these advantages equate to an energy saving of between 15% and 54%". (source https://www.engas.com.au/faq/)

It's the Natural Organic solution

Compliant with a number of national and international standards, such as: ISO 5149, the ISO/IEC 60335 series, BS 4434–1995 as well as AS/NZS 1677, which also covers the professional use of hydrocarbon refrigerants in Australia

Skyline Energy stainless steel buffertanks

With the V35ZA we recommend using a 200Lt buffertank.

Installing a buffertank on a hydronic heat-pump allows for zoning without causing backpressure or flow-rate fluctuations which may trip the heat-pump.

Hydronic Buffertanks also reduce short-cycling which increases efficiency.

With a heat-pump hydronic system, heat energy is always readily available so a larger buffertank is not necessary and in fact can reduce efficiency. (one reason why we don't recommend multiple potable hot water heat-pumps for hydronics)

Simplified rules for sizing your Skyline Energy hydrocarbon heatpump for hydronic heating

- for MAXIMUM EFFICIENCY AND SERVICE LIFE!

• Calculate how many kW are required
• Look at the climatology of the location to establish the duration of 0^oC to +4^oC. Don’t just look at the extreme temps, look at the mean overnight temp and duration
• If the ambient air temp rarely dips below +4^oC or does so for short periods then you can use this simple calculation...
      3.3 x electricity input kW = heatpump output heat kW to size the heatpump.
• If the mean overnight ambient air temp is between 0^oC and +4^oC change the calculation to
      2.2 x electricity input kW = heatpump output heat 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.
• Warranty service may be refused if our sizing guidelines are ignored.
