EnerWorks announced that their Spectrum solar water-heating appliance with a double-walled heat exchanger has achieved CSA certification, the only double-walled system to meet the necessary requirements to date. The certification applies to EnerWorks’ one- to four-panel systems.

EnerWorks’ Spectrum appliance with a single-wall heat exchanger was also the first solar thermal system to achieve CSA system certification, and has been certified since 2006.

“The difference between these two appliances is that the energy station contains a heat exchanger with double wall construction”, says Andrew Mauchlen, EnerWorks Engineering Manager. “This means that in the unlikely event that there is a leak in the heat exchanger, the food-grade heat-transfer fluid would leak out of the system, providing a visible indication of the leak.”
