Label 1
  • Ideal for use with renewable energy such as heat pumps, solar, heat recovery and in district heating schemes due to large primary store
  • Reduces legionella risk due to temperature: hot water stored at > 60°C
  • Low maintenance with no anode protection required
  • The carbon steel coil enables this product to be used in a variety of installations including system separation for a heating circuit
  • 5-year warranty
  • Low standing losses – cylinder comes with thick polypropylene jacket (100mm Polyurethane mattress for models SLME600 and SLME800)
  • Can provide dual temperature outputs for different circuits such as underfloor heating (low temperature) and DHW (high temperature)
  • Suitable for unvented systems –supplied as a complete package including 3.5 bar mains unvented kit*
  • Maximise capacity of the cylinder with DHW mixing valve and 2 port valve supplied as standard*
  • Supplied with 3kW immersion heater* (6kW option available)
  • Smaller models (SLME 400-600) fit through a standard doorway for access to plant room
  • Cost effective solution, simple installation with no de-stratification kit needed and no flue requirements
