Both are noble materials, but the importance for a fireplace insert or a wood stove are: design, develop many kw and above that they yield.

Differences of a fireplace insert or wood stove cast iron or steel are:

 

A fireplace insert or wood-burning stove in steel, has the characteristic of rise in temperature faster than a cast iron power, but when you are not eating more combustion, it drops in temperature much more rapidly than cast iron, for the fact that the thicknesses place normally used are very finest of castings in ghisa.La heat distribution in a steel product is not homogeneous.

 

A fireplace insert or stove iron salt more slowly in temperature at power as shims merger are greater, the lead you have a much more even heat distribution than with steel and heat sealing it has for several hours when not feeding more fire.

 

Below the values ​​on a scale from 1 to 3 stars

 

Fireplace insert or wood stove steel, reaching temperatures of 3 ***

Fireplace insert or wood stove steel, even distribution of heat ** 3

 

Fireplace insert or wood stove cast iron, temperature reached about 3 **

Fireplace insert or wood stove cast iron, even distribution of heat 3 ***

 

So both are noble materials for use in construction of fireplace inserts and wood stoves, logically cast iron ones have a greater thickness and therefore generally a longer warranty, normally cast iron products have a warranty of 5 years against those steel of 2 years.

 

The value that is a good fireplace insert or wood stove is a good product you have from time to guarantee that the manufacturer assigns up to that bill that is 2 years, the nominal thermal output of the insert fireplace and above the yield of the product.
