Abstract: A fireplace system may comprise a burner comprising an upper portion shape and a front sloping surface sloping downwardly; and/or a log comprising a recess disposed into a bottom surface of the log. The recess may comprise a recess shape complementary to at least a portion of the upper portion shape of the burner, wherein the log may be disposed over the burner such that at least a portion of the burner is disposed within the recess. The burner may be disposed in the recess of the log such that the log hides the burner from view from a position in front of the fireplace system.

Abstract: A fireplace system can comprise a firebox and a heat exchanger. The heat exchanger may be in fluid communication with ambient air and may comprise an inlet configured to draw air into the front of the heat exchanger. Operation of a fireplace system comprising a heat exchanger may produce airflow through the heat exchanger by natural convection. The airflow through the heat exchanger may reduce heat transmission from the firebox and the fireplace system.

Abstract: A control network, system and method is disclosed for control of a plurality of entities. The control network comprises a control hub, a data repository and a plurality of control agents. The data repository models each entity as a plurality of granular components, each granular component having a type selected from a set of granular component types. The control hub is configured to receive performance data on each entity, translate the performance data into data on the granular components and store the transformed data in the data repository in association with its respective granular component. The control hub is further configured to determine an optimal control action in respect of a granular component of one of the entities in dependence on the granular component's transformed data and on transformed data in the data repository for other granular components having the same type.

Abstract: A fireplace system can comprise a first safety barrier and a second safety barrier disposed across a firebox opening and defining an interbarrier space. A fireplace system can also comprise a heat exchanger in fluid communication with the interbarrier space. The interbarrier space and heat exchanger may further be in fluid communication with ambient air. Operation of the fireplace system may produce natural convection through the interbarrier space, resulting in cooling of the safety barrier and the fireplace system.
