Many​‍​‌‍​‍‌​‍​‌‍​‍‌ New Zealand homeowners of late are choosing outdoor hot water cylinders as a fast means of creating more space inside the house, making the system safer, and enhancing its performance in ​‍​‌‍​‍‌​‍​‌‍​‍‌general. Given New Zealand’s updated building regulations and the trend towards smaller house designs, moving your hot water system outside can be a clever and effective way to ​‍​‌‍​‍‌​‍​‌‍​‍‌upgrade.

 

Why More NZ Homes Are Moving Their Cylinder Outdoors

Space​‍​‌‍​‍‌​‍​‌‍​‍‌ is probably the biggest advantage of an outdoor cylinder. A domestic hot water cylinder is often a great space consumer in a kitchen cupboard or a laundry room of a house. If the cylinder is installed outside, it will free up storage space or space for other appliances and give more flexibility in the apartment layout.

Additionally, an outdoor hot water cylinder will provide better air circulation and will be more accessible for any servicing, repair, or maintenance ​‍​‌‍​‍‌​‍​‌‍​‍‌works.

 

Built to Withstand New Zealand Weather Conditions

Modern outdoor cylinders are engineered to handle NZ’s wide range of conditions:

  • UV-resistant outer casing
  • Rust-resistant materials
  • Weatherproof electrical components
  • Advanced insulation to maintain heat even in colder climates

This means long-lasting performance and durability, even in areas with heavy rainfall or coastal exposure.

Ideal for Mains Pressure Systems

Most outdoor cylinders are designed specifically for mains pressure, giving your household:

  • Stronger showers
  • Faster tap response
  • Better compatibility with modern plumbing fixtures

If you’re upgrading from low pressure, moving to an outdoor mains pressure cylinder can be a highly efficient two-in-one improvement.

 

Keeping Your Home Safer and More Energy Efficient

Outdoor installations offer several safety and efficiency benefits:

  • No risk of indoor leaks damaging carpets or flooring
  • Improved ventilation around the cylinder
  • Easier access for regular service checks
  • Reduced indoor noise and heat

You also free up indoor space without compromising on water flow or heating performance.

 

Best Homes for Outdoor Cylinders

Outdoor cylinders are ideal for:

  • New builds with limited indoor cupboard space
  • Homes undergoing renovation
  • Properties upgrading to mains pressure
  • Households wanting safer and cleaner indoor environments

For older homes, electricians and plumbers can easily adapt existing connections to support a new outdoor setup.
