Split System

A split system is superior when you need installation flexibility or maximum quietness. Because the compressor is separate from the cylinder, you aren't restricted to having the entire unit sitting in one spot outdoors.

• Complex Layouts: Ideal if you want your cylinder inside a cupboard but the heat source outside.
• Space Constraints: Perfect for narrow side-yards where a large integrated unit won’t fit.
• Performance: Generally offers higher efficiency (COP) and faster recovery than all-in-one units.

Most split system installations range from $9,500 to $13,500, including GST. While the initial investment is higher than an integrated unit, and the long-term savings often provide a better return.

• Premium Technology: This price reflects high-end components from brands like Panasonic, Daikin, or Rinnai.
• Installation Variables: The final cost depends on the distance between the indoor cylinder and other site considerations.
• Operating Costs: The higher efficiency ratings mean your monthly power bills are typically lower than with any other water heating method.

Yes, split systems are the quietest option available. Because of the split system design, we have more flexibility in where the outdoor unit can be installed.

• Panasonic CO₂: This unit is a market leader, operating at an exceptionally quiet 37dB.
• Vibration-Free: Split unit compressors are usually placed on anti-vibration feet.

Yes, split systems generally offer the fastest recovery rates on the market. They are specifically engineered to handle the high demands of large New Zealand families.

• High Demand: They can reheat a large volume of water much faster than standard electric cylinders or entry-level integrated units.
• Consistency: Brands like Rinnai and Panasonic ensure that even after back-to-back baths or showers, the system replenishes hot water rapidly.

Yes, they are the preferred choice for multi-level properties. Because the cylinder can be placed centrally within the home (even on an upper floor), you don't have to wait for hot water to travel all the way from the ground floor.

• Efficiency: Centralised placement reduces heat loss through long pipe runs.
• Aesthetics: The outdoor compressor can be tucked away at ground level or on a balcony, keeping the main exterior of the house tidy.

A split system is likely the best choice if you have a unique layout or high hot water usage. If your current cylinder is tucked deep inside the house and you don't want to move it, a split system is usually the only viable heat pump upgrade.

• Free Assessment: A2W provides a free home assessment to measure distances and check your electrical capacity.
• Tailored Advice: We compare your daily usage against your home's layout to recommend either a 190L, 270L, or larger 340L capacity.
