That makes the control system simple and independent of a line voltage circuit, which is why millivolt heaters remain popular on remote installations and on systems where the owner wants the fewest possible electronics between the thermostat and the burner.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePolymer headers and a copper exchanger\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe headers are the water side end caps, and they take the worst of the chemistry. Polymer will not corrode or scale the way cast iron does, so it removes the failure mode that ends most older heaters. The copper exchanger handles the heat transfer itself, which is the pairing Raypak has used across the atmospheric line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSizing\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAt 199.5K BTU this is the small end of the R206A to R406A atmospheric range. Size a heater against pool volume, the temperature rise you want, and how exposed the pool is to wind and evaporation. An undersized heater runs constantly and never quite catches up.\u003c\/p\u003e","brand":"Raypak","offers":[{"title":"Default Title","offer_id":48626211160276,"sku":"RAY-009200","price":3333.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_0f25c856-9347-49d0-add3-542da2af8072.png?v=1788706162","url":"https:\/\/www.activepoolsupply.com\/products\/raypak-p-r206a-mp-c-57-propane-gas-heater-199-5k-btu-millivolt-plus-polymer-headers-copper-exchanger-197-lbs","provider":"Active Pool Supply","version":"1.0","type":"link"}
