The Elecro Evolution 2 9 kW electric pool heater<\/strong> is a compact, fully titanium-constructed heater designed to reliably maintain your swimming pool or spa at the perfect temperature. Manufactured by Elecro Engineering in Hertfordshire, England, the Evolution 2 is the upgraded successor to the original EVO range \u2014 and a direct drop-in replacement for any existing EVO installation. With 100% heating efficiency throughout its lifespan, it is one of the most dependable electric pool heaters on the market.<\/p>\n The 9 kW model is suitable for pools up to 60,000 litres (60 m\u00b3) and operates on both 230 V single-phase and 400 V three-phase power supplies, making it a versatile choice for both residential private pools and spa installations.<\/p>\n The Evolution 2 features a Grade 1 titanium flow tube and titanium heating element \u2014 the highest-grade titanium available. This makes it fully resistant to corrosion from chlorinated and saltwater pools, including those using salt electrolysis (salt chlorinators). The unique Vortex heating element technology<\/strong> keeps the element clean by creating a swirling flow of water, preventing limescale and mineral deposits from building up and extending the heater’s service life significantly.<\/p>\n The Evolution 2 arrives fully equipped and pre-wired, making installation straightforward. The unit is supplied with both a 1.5″ BSP (38 mm) and 50 mm stepped ABS union, ensuring compatibility with a wide range of plumbing setups \u2014 including flexible pipe systems and above-ground pools such as Intex or Bestway. Two swivel feet on the base allow the heater to be mounted either flat on the floor or vertically against a wall, depending on your technical room layout. The heater must be installed indoors or under cover, protected from the elements.<\/p>\n The thermostat is adjustable from 0 \u00b0C to 45 \u00b0C, giving you full control over your desired water temperature. The analogue control version features a 1.2 \u00b0C differential, while the digital version offers a more precise 0.5 \u00b0C differential with a selectable multilingual display. This makes it equally suitable for swimming pools and spas where exact temperature control matters.<\/p>\n The Elecro Evolution 2 incorporates several layers of protection to ensure safe, unattended operation. A rhodium-tipped reed flow switch with a titanium fulcrum pin<\/strong> monitors water flow at all times \u2014 if flow drops below the minimum threshold (4 m\u00b3\/h for the 9 kW model), the heater shuts off automatically. A thermal cut-out at 60 \u00b0C<\/strong> (manual reset) provides secondary overtemperature protection. Combined, these safeguards protect both the heater and your pool equipment from damage.<\/p>\nTitanium construction for long-lasting performance<\/h3>\n
