Tapstat Cylinder Controls(3)
  • Self acting (non electric)
  • Range limiting stops
  • Remote sensor with 2m capillary
  • Compression fittings for copper pipe
  • Simple to install

Self-acting tapstats control domestic hot water temperatures on gravity or pumped primary systems preventing scalding and fuel wastage
