A door latch system for a heating system is provided. The door latch system may be installed with a fireplace, wood stove, pellet stove, or other suitable system. The door latch system comprises a handle, a handle head and a catch. The handle head may be configured to engage the catch. Moreover, the catch may be configured with a self adjusting tension system, such that when the handle head engages the catch, the catch is configured to exert a tension force on the handle head. This tension force also causes the handle head to compress the seal of a fireplace door where the door latch system is installed.

The door latch system of claim 1, wherein the handle, in the first orientation, is configured to engage the handle mount, such that the handle is retained on the handle mount by at least a portion of a weight of the handle. 3. The door latch system of claim 1, wherein the handle, in the second orientation, is configured to exert a second torsion force on the handle head which is greater than a first torsion force, where the handle is in the first orientation. 4. The door latch system of claim 1, wherein the handle has a curved outer surface. 5. The door latch system of claim 1, wherein the door latch system is coupled to an appliance. 6. The door latch system of claim 5, wherein the appliance is at least one of a heating system, a freezer, and a refrigerator. 7. The door latch system of claim 1, wherein the tensioner mechanism comprises a spring. 8. The door latch system of claim 1, wherein the tensioner mechanism comprises a flexible bushing. 9. A fireplace, comprising; a door;an engagement comprising a handle mount having a first end and a second end opposite the first end;a handle removably coupled to the handle mount, wherein the handle may be slidably coupled to the handle mount at the first end to produce a first orientation and at the second end to produce a second orientation;a catch mechanism coupled to the door, the catch mechanism comprising a first tensioner and a first tensioner adjustment mechanism;wherein the engagement is configured to operatively engage the catch mechanism in response to a first torque applied to the handle in the first orientation; andwherein the engagement is configured to operatively engage the catch mechanism in response to a second torque applied to the handle in the second orientation. 10. The fireplace of claim 9, further comprising; a housing configured to operatively couple to the catch mechanism;a door rotatably coupled to the housing;a firebox partially enclosed within the housing and substantially sealable by the door. 11. The fireplace of claim 10, wherein the firebox is sealed by the door in response to at least one of the first torque and the second torque. 12. The fireplace of claim 9, wherein the tensioner is a spring. 13. The fireplace of claim 12, further comprising a spacer associated with the tensioner, wherein the spacer may be at least one of removed and added to adjust a tension force associated with the tensioner. 14. The fireplace of claim 9, wherein the engagement has at least one of a C shape and a U shape. 15. The fireplace of claim 9, wherein the tensioner has a first spring force and wherein at least a portion of the first spring force is applied tangentially to the engagement in response to at least one of the first torque and the second torque. 16. A method for closing a fireplace door to a fireplace, comprising: providing the fireplace door comprising a door seal and a door latch system, wherein the door latch system comprises a removable handle coupled to a handle mount, and wherein the handle mount comprises a first end and a second end opposite the first end;providing a fireplace comprising a self-tensioning catch;coupling the handle at the first end of the handle mount to produce a first orientation;applying a first rotational movement to the handle in the first orientation, wherein the rotational movement causes a first torque to be exerted on the handle head, and wherein in response to the torque the handle head pivots to at least one of engage and disengage the catch;coupling the handle at the second end of the handle mount to produce a second orientation;applying a second rotational movement to the handle in the second orientation, wherein the second rotational movement causes a second torque to be exerted on the handle head, and wherein the second torque is greater than the first torque. 17. The method of claim 16, wherein the self-tensioning catch comprises a spring having a first spring force. 18. The method of claim 17, wherein the self-tensioning catch further comprises a spacer, and wherein at least one of an addition of the spacer and a removal of the spacer changes the first spring force. 19. The method of claim 16, wherein the handle is removable to reduce a thermal stress of the handle.
