Insulation kit for hot water boiler

Abstract

The insulation kit for covering a hot water boiler has a series of insulation panels joined to each other along straight joints and corner joints. Each of the straight joints and corner joints has elastic tape mounted transversely thereon in a stretched mode, for maintaining the joint in a compressed state. In another aspect, each vertical corner joint is a miter joint forming a right angle, and is made with abutting edges each having a 55° bevel angle thereon in a relaxed mode.

[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 071,434 filed Apr. 29, 2008.FIELD OF THE INVENTION[0002]This invention pertains to an insulation kit for hot water boiler, and more particularly, it pertains to an insulation kit wherein the joints thereof are held in a compressed state.BACKGROUND OF THE INVENTION[0003]The rising cost of heating oil has created a strong market demand for insulation kits for retrofit installation on domestic hot water reservoirs and hot water boilers. The material used in these kits consists of, or is entirely made of, plastic-based material such as foam or fiberglass. Plastic-based materials are known to shrink with time. In some instances a shrinkage of 4% has been reported. Therefore, the aging of the insulation in an insulation kit causes joints to open.

AI Technical Summary

Benefits of technology

[0012]In the present invention, there is provided a new and improved insulation kit for covering a hot water boiler. The insulation kit has a series of insulation panels joined to each other along corner joints and straight joints. Each of these corner joints and straight joints have elastic tape mounted transversely thereon in a stretched mode, for maintaining these joint in a compressed state. The elastic tape is a long-aging type tape so that the compression of all joints is maintained despite a substantial amount of shrinkage in the insulation material of the kit.

[0015]All the joints in the insulation kit are held in a compressed state so that the insulation performance of the kit is maintained despite aging-related shrinkage of its elements.

Problems solved by technology

The rising cost of heating oil has created a strong market demand for insulation kits for retrofit installation on domestic hot water reservoirs and hot water boilers.

Plastic-based materials are known to shrink with time.

Therefore, the aging of the insulation in an insulation kit causes joints to open.

Cracks and slots appearing along these joints reduce the insulating property of the insulation kits considerably.

Although every insulation kit of the prior art deserves its own merits, there is no suggestion in the prior art to address the problems associated with a deterioration of insulation property due to insulation shrinkage and the opening of joints.
