Why does a heat pump save energy?<\/h3>\n<p>A heat pump uses a refrigeration cycle, just like your refrigerator or air conditioner. It does not generate heat itself \u2014 it simply extracts heat from the outside air and transfers it into the water. Because it only moves existing heat instead of creating it, it consumes much less energy than an electric or gas heater \u2014 typically saving up to 75%~80% on heating costs in <a href=\"https:\/\/www.china-heatpump.com\/fr\/kolant-air-to-water-heating-cooling-heat-pump-3-5kw-to-9kw\/\">kolant heat pump<\/a>. So it can save energy.<br \/>\n<a name=\"145\"><\/a><\/p>\n<h3 id=\"a000145\">Q2:What kind of heat exchange does Kolant heat pump use?<\/h3>\n<p>L'\u00e9changeur de chaleur de la pompe \u00e0 chaleur pour piscine Kolant est fabriqu\u00e9 en titane et est pratiquement imperm\u00e9able aux dommages caus\u00e9s par la chimie de l'eau.<\/p>\n<p>Nous utilisons un \u00e9changeur de chaleur \u00e0 plaques de la meilleure marque pour la pompe \u00e0 chaleur air-eau.<\/p>\n<p><a name=\"146\"><\/a><\/p>\n<h3 id=\"a000146\">Q3:What is the exact temperature range that the unit will work within?<\/h3>\n<p>Kolant heat pumps are available in three series, each designed for a different operating range to match your local climate:<\/p>\n<table>\n<thead>\n<tr>\n<th>Heat pump series<\/th>\n<th>Operating range<\/th>\n<th>Best suited for<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Kolant swimming pool heat pump<\/td>\n<td>-10\u00b0C to 43\u00b0C<\/td>\n<td>used in Mild and warm climates<\/td>\n<\/tr>\n<tr>\n<td>Low-temperature heat pump<\/td>\n<td>-15\u00b0C to 43\u00b0C<\/td>\n<td>Cold climates<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/www.china-heatpump.com\/fr\/kolant-evienhanced-vapor-injection-heat-pump-technology-create-a-new-era-of-energy-saving\/\">Kolant EVI heat pump<\/a><\/td>\n<td>Down to -35\u00b0C (lab-tested); -34\u00b0C recorded on site in Kazakhstan<\/td>\n<td>Extreme cold climates<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><a name=\"147\"><\/a><\/p>\n<h3 id=\"a000147\">Q4:Is it safe for Kolant heat pump operation?<\/h3>\n<p>Yes. Kolant heat pumps are built with high-quality insulation and electrical isolation to ensure safe operation. All models are designed to comply with international safety standards and are certified with CE \/ CB \/ RoHS\/ UL.<\/p>\n<p>As with any electrical appliance, safe operation depends on correct installation and proper usage. We therefore recommend that installation and maintenance be carried out by qualified technicians following the instruction manual.<\/p>\n<p><a name=\"148\"><\/a><\/p>\n<h3 id=\"a000148\">Q5:Does the unit ever need draining?<\/h3>\n<p>When the air temperature is below 3\u00b0C, ice will build up on the evaporator because the moisture in the air will freeze after the heat is absorbed by the cold refrigerant. The unit will automatically defrost the ice by reversing the refrigerant flow. Ice will become water and be drained out of the unit through some holes in the bottom of the cabinet. So if the unit is used in such a low temperature, defrost water drains automatically \u2014 no manual draining needed.<br \/>\n<a name=\"149\"><\/a><\/p>\n<h3>Q6: What warranty and after-sales support do you provide?<\/h3>\n<p>We provide a <strong>2-year warranty<\/strong> covering replacement of parts with factory defects.<\/p>\n<p>As a standard policy, we also supply <strong>free spare parts with a value equivalent to 1% of the total order value<\/strong>, which our customers find sufficient for routine maintenance during the first two years of operation.<\/p>\n<p>For urgent cases, we can ship the required spare parts by <strong>DHL<\/strong> to resolve the issue as quickly as possible.<\/p>\n<p>Please note that our warranty does not cover damage caused by shipment, incorrect installation, or improper usage.<\/p>\n<p><span style=\"font-size: 16px;\">To make a warranty claim, please send us the model number, serial number and a brief description of the issue \u2014 our after-sales team will respond within 24 hours.<\/span><\/p>\n<p><a name=\"150\"><\/a><\/p>\n<h3 id=\"a000150\">Q7:What about the payment terms?<\/h3>\n<p>For normal orders we request L\/C or 30% prepayment to start production,balance to be paid before delivery.<br \/>\n<a name=\"151\"><\/a><\/p>\n<h3 id=\"a000151\">Q8:What is the refrigerant gas and does it comply with European regulations?<\/h3>\n<p>For the European market, we use <strong>R32 and R290<\/strong> refrigerants, which are:<\/p>\n<ul>\n<li><strong>Zero ozone depletion potential (ODP)<\/strong> \u2014 fully non-ozone-depleting<\/li>\n<li><strong>Low Global Warming Potential (GWP)<\/strong>: R32 \u2248 675, R290 \u2248 3<\/li>\n<li><strong>Compliant with current EU F-Gas regulations<\/strong><\/li>\n<\/ul>\n<p>Both refrigerants deliver high energy efficiency. R32 is the mainstream high-efficiency choice, while R290 is a natural refrigerant with an extremely low GWP \u2014 an excellent option for customers prioritizing sustainability.<\/p>\n<p>Please note: <strong>R290 is a flammable refrigerant (A3 safety classification)<\/strong>, so R290 units must be installed by certified professionals in accordance with safety regulations.<\/p>\n<p><a name=\"152\"><\/a><\/p>\n<h3 id=\"a000152\">Q9:Are there any restrictions as to where they can be sited?<\/h3>\n<p>There is almost no restriction for installation sites.
