Here's some news you can use from AERCO!
Effective immediately, the baseline SmartPlate models (both double wall and single wall configurations) will see the new plumbing without use of ProPress fittings, Higher Boiler Supply Temperature of up to 250°F and 5-year Heat Exchanger Warranty as a standard offering at no added cost. The current ProPress design is being discontinued effective immediately and all shipped orders will have this new baseline.
The design also incorporates a boilerside relief valve option if required by local codes (NYC for example) or if desired for added safety on the boiler side.
