Millivolt Boiler Controls
Question: Are Millivolt Residential Gas Boiler Controls practical and reliable.
Given: A standing pilot burner is required or Millivolt transformer.
Components: It appears that the basic control components are readily available. The Powerpile Generator, Gas Controller, Aquastat and Thermostat for small residential applications are available. Not sure if Low Boiler Water Cutoff or Weather Responsive Boiler Controls ave out there for Millivolt systems. Perhaps a switching relay could allow a 24 volt Low Water Cutoff to interrupt the Millivolt power circuit. Don't want to loose the generator to a transformer requiring outside power.
Reliability: Is the Powerpile Generator the weakest link in this control system? To insure reliability, should the generator be changed say once a year? Anyone out there with experience with Millivolt Controls please make positive or negative comments about their general use.
