Ducted gas heating can last anywhere between ten and 20 years with the average lifespan being 15 years. The longevity of the system depends on how well it is maintained and serviced throughout its life.
There are a few reasons to replace your ducted gas heating. If you have a very old model it may still be running fine, however older models can be very inefficient and can result in higher costs on your energy bill. You may assess that savings offered by a modern, energy efficient system more than make for the cost of replacement.
Likewise, if your system is old and not working as well as it should, there may be the option to replace certain parts to bring it back up to optimal operation. However in cases where the heat exchanger is broken it is probably necessary to do a full system replacement. Airomania’s expert technicians can assess this for you, advise, and carry out the necessary repairs or replacement.
Like any system however, the best option is to keep it well serviced and optimally operational over its lifespan. Airomania offers full servicing of ducted gas heating systems, and can do so on an ongoing schedule which will ensure that your system lasts as long as it possibly can.
There are a few factors that contribute to the longevity of ducted gas heating system:
Buying a high quality heater from a reputable brand will go some way to ensure that the heater lasts well. In additional we recommend that you choose a brand that offers a heat exchanger warranty of more than five years.
Older models of gas heating have heavy gauge metal heat exchanges and these can last for up to 30 years, however the drawback to them is that they are nowhere near as energy efficient as the newer steel heat exchangers.
Newer model heat exchangers are made of aluminize or stainless steel. They do not last as long but they will save you on energy costs. This can be a consideration when thinking about whether to replace your existing system. It may be working, but costing you a lot more on your energy bill.
The right model
Getting a heater that is the right capacity for the space you want to heat is essential, as an undersized heating system will have to work harder to heat the space and therefore the lifespan may be reduced (not to mention that it won’t be as effective at keeping you warm!).
Like any system if you keep it serviced and running smoothly, it will last longer. Regular servicing will keep all the components operational and improve the lifespan of the system.
