Not all boilers are of the same worth. While there of course the major differences between gas and oil boilers, there are far more versions than just multiple fuels, however for decades, cast iron boilers were the standard. As wild as it may sound, you can still encounter them in use this week, but cast iron boilers can last forty years or more if properly cared for! However, older does mean more effective, however this is because cast iron boilers are a very old type of Heating and AC technology. The most formidable issues with a cast iron boiler is the material itself. Cast iron can shatter in the cold due to drastic temperature drops. Unlike other current materials, it can also start to corrode. While a cast iron boiler can last fifty years or more, it will not run at its peak. These different models tend to simply develop more shatters and become worse and worse overtime, until they are finally upgraded by an Heating and A/C company. This is why the most efficient boilers made this month are steel. Whether your house is built for gas or an oil heater, a steel boiler can be fitted for your needs. Much different from the older cast iron models, steel boilers are are resistant to corrosion and won’t crack due to temperature gets lower. The latest steel boiler I purchased even saves myself and others currency on oil, because it doesn’t run all the time, it only heats water when the people I was with and I need it for the house or need it to heat the home. An powerful steel boiler can last for 35 years or more, and continue to run at peak performance with consistent repair from your local Heating and A/C service provider.
