frequently asked questions

FAQs
For instantaneous Hot Water?

What’s the difference between an instantaneous and a traditional hot water cylinder?

Instantaneous systems heat water on demand, meaning there’s no storage tank and no energy wasted keeping water hot. Traditional cylinders keep a set amount of water heated at all times, which can lead to higher power bills and running out of hot water.

Are Thermann and Rinnai systems suitable for Auckland weather?

Yes both brands offer models with frost protection, making them well-suited to Auckland’s cooler winters. Rinnai also includes optional temperature control and smart technology for extra comfort.

Will an instantaneous system give me enough pressure for multiple showers?

Absolutely. When correctly sized for your home, these systems provide continuous flow hot water with strong, consistent pressure even when multiple taps are in use.

Can I switch from electric to gas hot water?

Yes many Auckland homes are making the switch to gas for improved efficiency. Our team can assess your setup and provide a full gas conversion if needed.

How long does installation take?

Most installations are completed in half a day. If we’re replacing an existing gas system, it’s often a straightforward job. Full conversions may take a bit longer, and we’ll keep you fully informed at every step.
