Better hydraulics also mean the heater puts less back pressure on the pump, so the whole system works less hard for the same result.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe cupro nickel exchanger\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe heat exchanger is cupro nickel as standard. Pool water that drifts out of balance is what kills gas heaters, attacking the exchanger from the inside until it fails early. Cupro nickel resists that, which is why the same heater keeps performing season after season on real world water rather than ideal water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOperation and delivery\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe electronic control panel is straightforward to set, so owners spend less time at the panel.
