Thermann X Split 315L Heat Pump Hot Water System

Save more with Thermann

The Thermann X Split 315L hot water system can deliver significant savings partly because they qualify for government financial incentives like Small-scale Technology Certificates (STCs) and, in some states, additional schemes such as Retailer Energy Productivity Scheme (REPS) rebates. STCs are created under Australia’s Small-scale Renewable Energy Scheme — when you install an eligible renewable system like a heat pump hot water unit, you can claim a number of certificates based on the estimated energy the system will save over time. These certificates have a market value and are effectively tradable, which means installers or brokers can assign you a monetary rebate that knocks down the upfront purchase and installation cost.

Combining STCs with additional rebates can lower the purchase price substantially — sometimes by hundreds to over a thousand dollars — making high-efficiency systems like the Thermann X Split more affordable.

How does the Thermann X Split 315L save you money?

The Thermann X Split 315L heat pump hot water system is a smart way to lower your energy bills without sacrificing comfort. It works by drawing heat from the air to heat your water, using far less electricity than a traditional electric system. That means you could save up to 65–70% on your hot water running costs over time. The split system design also helps keep things quieter and gives you more flexibility with installation. If you have solar, or can take advantage of off-peak electricity, you can save even more. Plus, with available government rebates and STCs helping reduce the upfront cost, it’s an efficient, cost-effective upgrade built for long-term performance.
