Proactive Hydronic Boiler Control System With Weather Anticipation

Update: January 7, 2020 The United States Patent and Trademark Office (USPTO) granted a patent for our Hydronic Boiler Control System With Weather Anticipation. Additional patents are pending in the United States and other jurisdictions.

*****
Typical reactive indoor / outdoor hydronic boiler temperature controllers used in large residential complexes monitor the outdoor temperature, and use this information to adjust the boiler temperature based on the outdoor temperature. As the outdoor temperature drops the boiler temperature is raised and as the outdoor temperature rises the boiler temperature is lowered.

When a thermostat in an individual apartment or condominium reaches the desired set point it sends a signal to close the zone valve. Controlling the boiler water temperature relative to the outside temperature minimizes the zone temperature overshoot after the zone control valve is closed.

Our patented Weather Anticipating Hydronic Boiler Controller monitors internet based weather forecasts and proactively adjust the Hydronic boiler temperature in advance of outdoor temperature changes. When it is cold and the weather forecast indicates that it will be getting warmer that our hydronic boiler controller adjusts the hydronic boiler temperature lower in advance of the change in outside temperature.

Most boiler installations with indoor outdoor temperature controllers also shut off the boiler when the outdoor temperature rises above a predetermined outdoor set point and turn the boiler back on when the outdoor temperature drops below the predetermined outdoor set point.

In this example our Weather Anticipating Hydronic Boiler Controller monitors the weather forecast data and shuts off the non-condensing Hydronic boiler 2.5 HR before the outdoor temperature rises. The residual heat in the hydronic system maintains zone temperatures and the operational time of the boiler and energy consumption is reduced by over 20%.




In this example our proactive weather anticipating hydronic boiler temperature controller monitors the weather forecast data and lowers the hydronic boiler temperature in advance of the actual outdoor temperature with an estimated savings of 11% for this day.

Our systems use Wireless Internet Connection so installation or upgrades are quick easy and another benefit of our system is remote monitoring and including boiler alarm notifications, allowing service personal to be dispatched before the tenants call.
