How iStore Performs in Ashburton's Climate

Very GoodClimate Zone 6 | R290 refrigerant

iStore's R290 refrigerant is well-suited to climate zone 6. Propane (R290) holds its output in cooler conditions better than R134a does, making iStore a strong choice for this area. Winter mornings below 5 degrees will reduce efficiency slightly, but the system recovers quickly as temperatures rise.

Noise Levels in a Metro Area

At 50dB, iStore is on the noisier end of heat pumps. In a metro area, careful placement is essential to avoid neighbour disputes. Check your local council's noise regulations and avoid installing near bedroom windows or boundary fences.

How does the Victoria gas ban affect Ashburton?

Planning your switch to a heat pump now lets you choose the best system and installer on your timeline.
How long does a heat pump installation take in Ashburton?
A standard heat pump hot water installation in Ashburton takes 3-5 hours for a straightforward replacement. If you're converting from gas, it may take a full day as the installer needs to connect new electrical circuits and potentially modify plumbing. Metro installers typically have availability within 1-2 weeks.
What size heat pump do I need for my Ashburton home?
For Ashburton in climate zone 6: 1-2 people need a 150-170L tank, 3-4 people need a 250-315L tank, and 5+ people should consider a 315-400L tank. In cooler climates like yours, sizing up one tank size is recommended to ensure adequate hot water on cold mornings.
