Calitec NZ WH-70 Water Heater + 300L Cylinder

Review

Performance & Efficiency:

Calitec designs it’s own product range for New Zealand’s unique challenges and offers the longest warranties available on the New Zealand market to reflect their confidence in the quality and durability of their products.

COP of 5.0 at 18°C ambient is strong, and the R290 refrigerant (GWP 3) is the lowest-impact option available.

The Calitec WH-70 is a genuinely unusual product in the NZ market — it uses a water circulation system rather than the refrigerant-to-tank approach of most heat pumps. The outdoor mono block heats water directly and circulates it to the separate cylinder, which means the cylinder can be positioned up to 20 metres away and placed either indoors or outdoors. Allowing a lot of flexibility over placement.

Features:

• 20 year warranty: The duplex 2205 stainless steel cylinder is the headline spec here: Calitec backs it with a 20-year warranty, which is the longest tank warranty in our entire database by a significant margin.
• Wi-Fi control, solar PV input, and a 3kW backup element are all standard. Designed specifically for NZ conditions, with a coastal-rated 304 stainless steel case on the outdoor unit.
• Pricing: Unit pricing is confirmed RRP including GST and NI delivery.

Supply and Service:
