Is price an indication of quality?
Stoves, like many other things are available in varying levels of quality, price and with differing warranties.
In many cases you get what you pay for but there are cheap stoves on the market which can perform as well, if not better than some of the more pricy brands so it is a good idea to ask advice from your stove retailer.
Most stoves have a minimum 12 month warranty but many have 3, 5 or 10 year some even come with a lifetime warranty, however, be sure to read the small print as most stove warranties only cover the outer body of the stove and not the ´consumables´ which may need to be replaced often to protect the stove body.
Generally a more expensive stove brand will also charge more for their spares and consumables than a cheaper brand so ongoing costs are also something to consider.
Although there are more and more companies offering non branded replacement firebricks and glass for stoves you will usually need to purchase replacement grates and baffles trough a stove retailer from the manufacturer to ensure a correct fit.
The material the stove is manufactured from can make a difference in the price but generally there are cheap stoves available in both Cast Iron and Steel, the quality or thickness of the material is likely to be lower the cheaper the appliance is.
Convector stoves are often priced higher than radiant models this is due to the manufactrer using more materials in the construction of a convecting appliance, as is the case with boier stove models.
