My Burnham gas boiler is 30 years old. Does it make sense to replace it now or wait til the thing craps out. I know the new boilers are more efficient but not sure if it makes sense dollar wise to change it out. Thanks Jim

You have to run your numbers on gas and cost, a new unit could save
15-17% on Ng
When you have it serviced the service man checks the efficiency. Get that figure and compare it to new boilers and see how many hears it would take to recover the replacement costs.
I'd leave it go for a couple more years. Put $500 in the bank every year, until then.
The service man cannot check the efficency of the unit, only burner efficency. Most old designs are 80% any way.
