  • Your purchase supports local, cooperative renewable energy manufacturing!


Hot water storage tanks
The BOLT-ON can be retrofitted with existing hot water storage tanks – just unplug your existing heating system and ‘bolt on the BOLT-ON’.
However, if you need to buy a completely new system, or want to upgrade to the most efficient system possible, you can also purchase a Eureka’s Future stainless steel water storage tank. In partnership with local business Everlast, Eureka’s Future is starting to manufacture ‘Solar Ready’ hot water storage tanks through Everlast’s factory in Dandenong. These stainless steel water tanks are the highest rated insulating tanks on the market, and are designed especially to be compatible with solar hot water (as well as gas or electric systems). To maximise the efficiency of your hot water system, having the highest quality insulated storage tank will mean you lose very little heat from your stored water.

How does the BOLT-ON work?
The BOLT-ON uses a reverse application of the technology found in household fridges, utilising the solar heat present in the air around the unit. The unit contains a refrigerant that boils at -26°C, This means that at any air temperature hotter than this, the refrigerant liquid becomes a gas, which can be compressed. When you compress air it gets hot (like when you put your finger over a bike pump and pump!). The BOLT-ON uses a very small amount of electricity (enough for household PV solar panels to power) in order to run a compressor. This compresses the refrigerant gas to superheat at 95°C. This heat is used to heat your hot water via the BOLT-ON’s Dynamic Cycle heat exchanger, and the water then goes to your water storage tank, ready to be used.
