Is there an alternative option to using Tridicators?

Yes, there is a great alternative option to using Tridicators, although this option is not as compact as a two-in-one pressure and temperature gauge. It requires two separate accessory ports rather than just one to install both a thermometer c/w thermowell and a separate pressure gauge on a pigtail syphon to reduce heat transfer to a standard pressure gauge. This option has four key benefits over using Tridicators as detailed below.

  1. With a valve on the pigtail syphon to enable isolation of the pressure gauge, the gauge can be changed out without shutting down the boiler system.
  2. Bi-metal thermometers do not have water coming directly into the gauge to sense the water pressure, so there is no risk of leakage inside the gauge.
  3. The installation of a thermowell allows the bi-metal thermometer to be changed without shutting down the boiler as the thermowell stays installed. The heat is transferred from the thermowell to the temperature sensing probe and bi-metal sensor.
  4. There is no need to change out both gauges if one of the two gauges was to fail.
