About Honeywell Aquastats

Aquastat is a Honeywell’s registered trademark and is a device used for temperature control in hydronic heating systems. High limit aquastats regulate boiler burners operation when thermostat call for heat. Low limit type aquatats are used with tankless coils to maintain water temperature inside the boiler outside the heating season (summer). Available in horizontal, vertical and strap-on mounting options and fixed, variable or manual reset differential temperature settings.
