V25ZA Hydrocarbon Hydronic Heating Air Sourced Heat Pump

For heating up to about 210sqm floorspace for panel radiators

For heating up to about 250sqm floorspace for concrete slab heating

Our V25ZA Hydrocarbon 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, charge them with Hydrocarbons, then 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.

The V25ZA can heat water to a maximum of 55oC
, (recommend design for 55/45oC for new radiator installations).
The dual compressor V25ZA can be spanned across 2 phases if you have 2 phase supply, or across 2phases of a 3ph supply.

We use Natural Organic hydrocarbons:

Our hydronic heat pumps use hydrocarbon instead of traditional refrigerant, a highly efficient blend of R290 and R170, propane and ethane. When switching from R22, R502, R407C, and R404A power bills can be dramatically reduced, and the wear and tear on the refrigeration system can also be minimised.

It's the Natural Organic solution

GPD32-9 hot water circulating pump

Recommended Primary Circulation Pump for V25ZA

We offer a small range of circulating pumps to suit a variety of applications.

An essential part of any hydronic heating system is the circulating pump or pumps.

The following table lists a range of circ. pumps to compliment our Air Sourced Hydronic Heat Pumps as primary circuit pump between the heat pump and the buffertank, and as the 'zone' pump(s) which circulate the water between the buffertank and the floorcoils and/or radiator panels.

The primary circulation pump must be matched to the flow-rate required by the heat pump.

The secondary or zone pumps are usually 0.5 to 1.5 Litres per second.

Some of our circulating pumps have 3 speeds to allow for varying conditions:

V25ZA primary pump (close-coupled buffertank)

Skyline Energy stainless steel buffertanks

With the V25ZA we recommend using one of specially designed Stainless Steel multi-port 200Lt or 400Lt buffertanks.

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 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 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...
        3.3 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
        2.2 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.
