For example, in a hotel where several domestic hot water circulation lines are present. It works as follows: If the return temperature in the installed line reaches, for example, 50° C, the thermostatic valve closes this line. This means that the other lines, which of course must also have a valve, are still flowed through by the circulation pump until 50° C is also reached there.\u003c\/p\u003e\u003cp\u003eThe valve does not close 100%, of course, so that the pump is not stalled, a minimum flow remains.\u003c\/p\u003e\u003cp\u003eThis leads to high energy savings, as no more hot water returns to the boiler. The valve also has a shut-off valve for service work.\u003c\/p\u003e\u003cp\u003eWe recommend that you also switch off the pump via an electrical return (thermostat) when the temperature is reached. Or a very sophisticated solution, to install an automatic circulation controller that automatically detects when hot water is drawn and only then switches on the pump.\u003c\/p\u003e\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eCondition:\u003c\/strong\u003e As good as new, never installed!\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eOur item number:\u003c\/strong\u003e P8\/536\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"Pumpenkost","offers":[{"title":"Default Title","offer_id":57275717321044,"sku":"P8\/536","price":125.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1078\/5620\/0020\/files\/foto_29.10.25_08_53_20.jpg?v=1790289280","url":"https:\/\/www.pumpenkost.com\/en\/products\/kemper-multi-therm-zirkulation-regulierventil-p8-536","provider":"Pumpenkost GmbH","version":"1.0","type":"link"}
