Frequently asked questions

Is US Boiler the same as Burnham?

Yes. U.S. Boiler Company makes the Burnham residential boiler line, so parts listed as US Boiler or Burnham come from the same manufacturer.

How do I find the right US Boiler replacement part?

Use the boiler model and size from the rating plate, for example Alta 150-200, and compare it to the model list on the part page. Many parts are specific to a size range within one model. See US Boiler parts.

Can I replace a US Boiler gas valve with any Resideo valve?

No. Use the gas valve listed for your boiler model, even when it is a Resideo valve, because the boiler maker sets the valve type, regulator and connections for that appliance.
