SOLAR WATER HEATING

Unlimited solar stocks a wide variety of solar specific valves that may be necessary in a solar installation.

  • Air Release Valve – used in an indirect system to ensure that there are no air locks interfering with the efficiency of the system.
  • Solar relief valve – Pressure Relief valve for 100kPa systems with integral Vacuum Relief.
  • Tempering valve – A tempering valve mixes hot water with cold water to protect the user from burning due to the temperature of the water being too hot. At Unlimited solar we recommend a tempering valve for every system
  • Dump valve – protects your solar system against freezing conditions by allowing water to pass through the system
