Steve…….We manufacture a device designed to do exactly what you want to do. There are a few added benefits to boot, not only will it prolong the life of the boiler, it will protect all the water distribution piping and recirculation lines connected to it from developing pin hole leaks, and will prevent leaching of heavy metal(Lead Tin Antimony) from old soldered joints and fittings in the system. We are authorized Ruud-Rheem installers, may be able to pass along a hint on how to make that heater last 20 years……Bud
