Disclosed are various space heater base brackets. A first thermal transfer component has a base bracket hole along its bottom edge. A second thermal transfer component has a locking hole along its bottom edge. A base bracket is between the first thermal transfer component and the second thermal transfer component. The base bracket has a tab that protrudes into the base bracket hole. The base bracket also has a locking mechanism corresponding to the locking hole in the second thermal transfer component.

A movable fluid fuel heater to heat air and to introduce it into an environment to be heated. The heater includes a flow rate variator device for varying the flow rate of oxidizing air introduced in the combustion chamber by a forced ventilation device between a minimum flow rate value and a maximum flow rate value. The heater also includes a reference device comprising a plurality of reference values of a parameter representative of the pressure and a plurality of reference temperature values of the environmental air upstream of the combustion chamber. The reference device is configured to suggest an optimal setting value to set the flow rate variator device, at each pair of values formed by a value of the plurality of reference values of a parameter representative of the pressure and a value of the plurality of reference temperature values.

A flameless heater includes a diesel engine, a hydraulic or electric load that is powered by the diesel engine thereby generating heat, a heat exchanger that transfers heat to air flowing through the air from the flameless heat source, and possibly other heat exchangers for heating the air flowing therethrough with engine coolant and/or with exhaust gases. The system may be operated to maintain relatively high load on the engine for at least the majority of the time so as to reduce or negate the need for parked regeneration. The system may also control airflow through the system and possibly other system parameters to obtain a given setpoint such as a given discharge air temperature. In one embodiment, airflow through the system is controlled by louvers under the power of an electric motor or other actuator controlled by the system's controller.

A water heater handle may comprise a connecting portion, a first pipe nut connected to the connecting portion on a first end of the connecting portion and configured for attachment to a first water tank piping connection, and a second pipe nut connected to the connecting portion on a second end of the connecting portion and configured for attachment to a second water tank piping connection.

An extrol tank catching device is disclosed, which is a tool designed for the safe removal of a #30 extrol tank. The extrol tank catching device comprises a body component that is configured in a basket-like shape and which is sized and shaped to accept a #30 extrol tank. Specifically, the body component is a cylindrical, reinforced mesh body with two nylon straps on top, each equipped with metal pinch adjusters for adjustment of the straps. Further, there are two large metal hooks that attach to the horizontal heating pipe above the #30 tank. Thus, the device's basket-like shape facilitates the safe and secure capture of the heavy #30 tank once it is unscrewed, ensuring it drops safely into the body component during replacement or maintenance of the tanks.
