The Nelyrho 25KG Propane Melting Furnace is a strong contender for those venturing into metal melting, especially for hobbyists and DIY enthusiasts. One of its standout features is its durable construction, made from premium stainless steel, which ensures stability and longevity. With a maximum heating output of 135,000 BTU, it can quickly reach impressive temperatures of up to 1400°C (2552°F), making it effective for melting various metals like aluminum, copper, and even gold.

However, there are a few points to consider. Weighing in at 43 pounds, the furnace may pose some portability challenges, making it less ideal for those who need to move it frequently. While the dimensions are manageable for a workshop setting, it requires a dedicated space due to its size. The furnace's efficiency is commendable, but users should be aware that it may need more careful monitoring, especially when reaching high temperatures to ensure safety.

The Nelyrho furnace is excellent for metal casting projects, offering good value in terms of performance and included accessories. However, consider its weight and space requirements when making your decision.

The 10kg crucible capacity is adequate for various small to mid-size projects.

The furnace also comes with a comprehensive accessory package including tongs, heat-resistant gloves, and a gas pressure regulator, adding to its convenience and ease of use. The ceramic wool and refractory cement lining provide excellent insulation and durability, ensuring efficient heat retention and prolonged life of the furnace. Additionally, the 16-gauge steel build offers sturdy construction, though at a weight of 70lb (31kg), it may not be the most portable option available.

The inclusion of a 6.5ft gas hose and clamps further simplifies the setup process for users. However, the weight and relatively large exterior dimensions may pose challenges for those seeking a highly portable furnace. Despite these drawbacks, this furnace is well-suited for those who prioritize high-temperature capability and robust build quality over portability.

The sturdy support stand adds an extra layer of protection by insulating floors from heat damage. Potential buyers should consider the additional cost and effort of acquiring and installing wheels for easier mobility. This furnace is likely best suited for semi-permanent setups in workshops or garages, given its substantial weight and size.
