Laars' residential oil-fired boilers come with a 1-year parts warranty and a non-prorated limited lifetime warranty for the heat exchanger. Gas boilers, however, come with a 1-year parts warranty, a 10-year non-prorated warranty on parts for the primary heat exchanger, followed by a limited 20-year warranty for the heat exchanger. For commercial boilers, the non-prorated vs. prorated period for the heat exchanger warranty is 5 and 10 years, respectively.
