My house has two furnaces: one gas (methane, or city gas) which I only use for water heating (showers, etc) and one wood pellet. They both warm up water in the heaters circuit, and can be used at the same way.
The gas one is more expensive to run (400€/month), but require zero maintenance, except some predictive maintenance like cleaning filters once a year in summertime.
The wood pellet one is way cheaper to operate (1.5k€/year, for 9 months of operation) but require weekly cleaning and daily fuel loading. Also for this one once a year maintenance is mandatory, deep cleaning, replacing some perishable parts and so on.
So, yes, every furnace require periodical maintenance to operate properly, and should work just fine for 10 or even 20 years if you are careful and do the proper maintenance.
