What are the Best Heating and Cooling Options for Solar-Powered Homes in Hawke’s Bay?

Targeting efficiency and independence: The Rinnai systems designed for your solar setup.

If you have invested in solar PV for your New Zealand home, you are on the right track towards energy independence. Now, the goal is to make sure your home's major energy users - heating and hot water - are working in perfect harmony with the clean electricity you generate.

The secret? Choose highly efficient electric appliances that can be programmed to run during the day when your solar panels are producing peak power. We've reviewed Rinnai's top-performing electric systems  to share the ideal partners for your solar PV installation, helping homes across Hawke's Bay to maximise their self-consumption.

Hot Water: The Smartest Use of Your Free Solar Power

Heating water is often the biggest energy draw in a Kiwi household. By switching from standard electric to a heat pump hot water system, you can slash your consumption and use your solar-generated power for the remainder.

1. Rinnai Enviroflo GR Integrated Heat Pump

• What is it? An all-in-one hot water heat pump where the heat pump unit and cylinder are combined. It uses a refrigeration cycle to efficiently draw heat from the air to warm your water.
• Why is it best for solar? The Enviroflo GR is explicitly Solar PV Compatible. It can directly interface with your grid-tied solar system to trigger heating cycles when your home is exporting surplus power. This ensures you are utilising every free kilowatt your panels produce.
• Efficiency Benefit: Saves up to 70% on hot water energy compared to a standard electric cylinder.

2. Rinnai HydraHeat Split Hot Water Heat Pump

• What is it? A split system that connects an outdoor heat pump compressor to your existing or a new hot water cylinder.
• Why is it best for solar? It features an in-built Timer Function. This allows you to precisely schedule the water heating to align with your solar PV system's peak performance hours, maximising self-consumption and heating your water for free during the day.

Space Comfort: Highly Efficient Rinnai Heat Pumps

Air-to-air heat pumps are the gold standard for climate control because they move heat, rather than generating it, making them incredibly power-efficient.

3. Rinnai Pro Series Heat Pumps

• What is it? A comprehensive range of units (high-wall, floor console, multi-split, and ducted) designed for powerful, energy-efficient heating and cooling in New Zealand conditions.
• Why is it best for solar? As one of the most efficient electric appliances for climate control, running a Rinnai Pro Series Heat Pump during the day is the lowest-load solution for all-seasons comfort. By setting your system to run during peak solar hours, you significantly reduce your reliance on expensive evening grid power for both heating and cooling.
