Reclaim Energy does not offer this for a couple of reasons. Firstly, rebates are only available for standalone heat pump water heaters. And secondly, the Reclaim Energy operational temperature is stable at 63°C, while solar thermal operational temperature fluctuates between 30-90°C, depending on the availability of solar energy. These two techniques can work against each other and one system can affect the thermal energy produced from another. The Reclaim Heat Pump can heat up a 315L tank in less than 3 hours, while solar thermal systems can take a full day. Combining two technologies can achieve a small return on energy savings, but requires a special tank and controller made for this purpose, which Reclaim Energy does not offer, or recommend, at this stage.
