| 20080223947 | Steam heating system with new steam baseboard - This new invention of steam heating system is derived from my new steam baseboards. This new system combines the merits from hot water heating system and traditional steam heating system, but without the shortcoming. We can control the temperature of each room or every floor. This system is easy to apply for large apartment buildings. This system has several zone valves to control the steam flow. The zone valve will be controlled by thermostats. The returned condensation water will be pushed by John's effect. There is no need for the returned water pipes. The new steam baseboard is made of copper. The heat transfer is much faster than the traditional cast iron radiator. The room temperature is much faster to reach. | 09-18-2008 |

| 20100072293 | STEAM CONTROL SYSTEM - A steam control system. An illustrative embodiment of the steam control system includes a boiler, a steam outlet conduit communicating with the boiler, a steam control valve provided in the steam outlet conduit, a controller connected to the steam control valve and an outdoor temperature sensor connected to the controller. | 03-25-2010 |
| 20110127343 | Wirelessly controlled heating system - The system includes a boiler, and multiple radiators connected to the boiler via a network of pipes. It includes a central processor for monitoring and control, air vent controllers that control the flow of steam through the radiators and a boiler control which turns the boiler on and off. The radiators are divided into groups. The central controller communicates with the air vent controllers to determine the conditions in the various groups. Based at least in part on the conditions, central controller may determine that the group requires heat. If heat is required and other parameters agree, central processor determines the state of the boiler. If off, the boiler is instructed to turn on and the air vent controllers in the group are instructed to open. Each air vent controller in that heat zone will then open allowing air to flow through the radiator and heat to be provided. | 06-02-2011 |

| 20140252101 | Automatic control of steam heating systems using remote sensors and switches utilizing thermodynamic qualities of steam with the existing system characteristics to increase heating cycle efficiency - An electromechanical analog or digital system that controls a steam heating cycle in one or more spaces is revealed herein. Said electromechanical system is comprised of pressure and temperature sensors, and pressure and temperature switches. Said sensors are installed into or onto a steam heating system, at the furthest steam circulation point physically accessible of said steam heating system. Said switches, by either mechanical or electrical means, receive temperature and pressure data from said sensors, respectively. Pressure and temperature switches are interposed between a thermostat and steam supply, as to oscillate steam supply until pressure and temperature set points of switches are achieved or set point of thermostat is achieved. The same aforementioned system can be controlled using a digital controller to take pressure and temperature sensors information into a controller that will interrupt or continue the call for heat from a thermostat to a steam supply. | 09-11-2014 |
