Where Performance Meets Architectural Purpose
Today’s architectural projects demand more than aesthetics — they demand systems that perform with efficiency, intelligence, and environmental responsibility. The Rinnai HydraHeat® Hot Water Heat Pump range, now installed by ATL, ticks every box for high-end, future-ready homes.
As one of the first certified HydraHeat® installers in NZ, ATL is delivering hot water systems that seamlessly blend performance with low-impact living — exactly what architects, developers, and discerning homeowners are looking for.
Designed for New Zealand, Built for the Future
HydraHeat® isn’t just another imported product. It was developed and engineered right here in NZ, specifically to handle local water habits, energy goals, and climate conditions.
Key to its success is thermal stratification — a smart heating method that prioritises hot water from the top of the tank, providing faster delivery with greater energy efficiency.
Quiet, Compact, Architect-Friendly
Architects know that space and sound matter. HydraHeat®’s low-noise operation and flexible indoor/outdoor tank placement options mean it suits a wide range of site plans and home designs. Its minimal visual footprint makes it ideal for integrating into clean, high-spec environments.
Whether you’re designing for suburban homes or premium rural builds, HydraHeat® aligns with smart living principles — from function to form.
Low Carbon, High Efficiency
HydraHeat® uses only 150g of R290 natural refrigerant — a sustainable choice with a low Global Warming Potential (GWP). Combined with energy use reductions of up to 75%*, it’s a high-impact solution for clients seeking Green Star points, or simply a smarter energy future.
It also features built-in frost protection, ensuring long-term reliability in colder locations across the country.
