It uses electronic ignition and a digital control panel, and it is rated for indoor or outdoor installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the 400K rating buys\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eInput rating is what decides how quickly a body of water comes up to temperature and how well it holds that temperature against cool nights and wind. At 400,000 BTU this is a serious heater, aimed at larger residential pools and light commercial water rather than a small backyard pool, where a smaller unit would be the better match.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eControls and ignition\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eElectronic ignition means there is no standing pilot burning fuel between calls for heat and nothing to relight after a windy night. The digital panel gives you a readable setpoint and a clear status, which makes diagnosing a fault far quicker than reading a mechanical thermostat and a pilot flame.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePlan the installation before you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThree things decide whether this heater suits your site. It is the natural gas version, so confirm the gas type at the meter. It is rated for 0 to 2,000 ft. of elevation, and that ceiling is firm. And it should be connected by a licensed gas fitter, who will size the gas line, verify supply pressure and set up venting for an indoor or outdoor location.\u003c\/p\u003e","brand":"Lochinvar","offers":[{"title":"Default Title","offer_id":48646206816468,"sku":"PSU-58282","price":4093.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_c23c0d38-1472-439e-aa5f-b543a01c432f.jpg?v=1788983090","url":"https:\/\/www.activepoolsupply.com\/products\/lochinvar-energyrite-pool-heater-400kbtu-digital-cntrl-ng-ern-402","provider":"Active Pool Supply","version":"1.0","type":"link"}
