Here&#8217;s an overview of the main options: <\/p>\n<h3>Heat Pumps : Our Recommendation<\/h3>\n<p>It&#8217;s <strong>the most economical solution<\/strong>. The heat pump captures free calories from the air and transfers them to your pool water. For every <strong>1 kW of electricity consumed, it delivers 5 to 15 kW of heat<\/strong>, depending on conditions.  <\/p>\n<p>We have selected the <strong>Polytropic<\/strong> and <strong>Hayward<\/strong> brands for their reliability and Full Inverter technologies (silence, savings, smartphone connectivity).<\/p>\n<p><strong>\u2192 <a href=\"https:\/\/www.astro-piscines.ch\/fr\/equipements-piscine-geneve-vaud-pompe-chauffage-couverture\/chauffage-de-piscine\/pompe-a-chaleur-piscine-silencieuse-geneve-polytropic-hayward\/\">Discover our Polytropic &amp; Hayward heat pumps<\/a><\/strong><\/p>\n<h3>The Heat Exchanger: For indoor pools<\/h3>\n<p>The plate heat exchanger allows you to connect your pool to your domestic heating system (boiler, geothermal system, home heat pump). It&#8217;s the ideal solution for <strong>indoor pools<\/strong> or pools close to the equipment room. Rapid temperature rise.  <\/p>\n<h3>The Electric Heater: an additional solution<\/h3>\n<p>Less expensive to buy (CHF 500-1,500) but <strong>very energy-intensive<\/strong> (1 kW consumed = 1 kW of heat). Reserved for small volumes, spas or occasional heating.

Effective for retaining heat and warming water on sunny days. Manual handling. Lasts 3-5 years.   <\/p>\n<p><strong>Solar-powered roller shutter<\/strong>: Higher investment but automated, secure and aesthetically pleasing. Lasts 15-20 years.

Above 30\u00b0C, the risk of bacterial proliferation increases. For children and the elderly, 28\u00b0C is ideal.  <\/p>\n<p><strong>How much does it cost to heat a swimming pool per month?<\/strong><\/p>\n<p>With a correctly sized heat pump, you can expect to pay CHF 100-150\/month for a 50 m\u00b3 pool heated to 28\u00b0C from April to October. With a solar shutter, the cost drops to CHF 50-100\/month. <\/p>\n<p><strong>Should you cover your pool to reduce heating costs?<\/strong><\/p>\n<p>Absolutely! An uncovered pool loses 80% of its heat through evaporation at night. A cover or bubble cover reduces consumption by 30-50%. It&#8217;s an essential investment.   <\/p>\n<p><strong>Is it safe to swim in Switzerland from April onwards?<\/strong><\/p>\n<p>Yes, with the right heating system! The heat pump can start heating as soon as the outside temperature rises above 5-10\u00b0C. Plan to start heating 3-5 days before your first swim of the season.  <\/p>\n<p><strong>What&#8217;s the difference between a heat pump and an electric heater?<\/strong><\/p>\n<p>Electric heaters consume a lot of energy (1 kW = 1 kW of heat). The heat pump is 5 to 15 times more economical, as it captures heat from the air (1 kW = 5 to 15 kW of heat, depending on the COP). <\/p>\n<p><strong>How long does it take to heat a 50 m\u00b3 pool?<\/strong><\/p>\n<p>With a properly sized heat pump, it takes 24 to 48 hours to gain 10\u00b0C. The temperature rise is faster if the pool is covered. <\/p>\n<p>For technical questions about heat pumps (models, Full Inverter, connectivity&#8230;), visit our dedicated page:<\/p>\n<p><strong>\u2192 <a href=\"https:\/\/www.astro-piscines.ch\/fr\/equipements-piscine-geneve-vaud-pompe-chauffage-couverture\/chauffage-de-piscine\/pompe-a-chaleur-piscine-silencieuse-geneve-polytropic-hayward\/\">FAQ Polytropic &amp; Hayward heat pumps<\/a><\/strong>[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][\/vc_column][\/vc_row][vc_row css=&#8221;.vc_custom_1765122949167{background-color: #FFFFFF !important;}&#8221;][vc_column][vc_column_text css=&#8221;&#8221;] Pool heating: Bathe 6 months a year instead of 3 [\/vc_column_text][vc_empty_space height=&#8221;5px&#8221;][vc_column_text css=&#8221;&#8221;]An unheated pool in Switzerland means a swimming season limited to July and August &#8211; barely 3 months a year.
