Thought I would add a little more information. I talked to a tech at Crydom to see if the specs of the TA1225 relay differ from the A1225, which is the more common relay. He told me not really and that it would be suitable for this application. He did suggest if I was mounting it to the base plate, to mount it upside-down, so heat wouldn't pass through the entire body of the relay. His preference was to mount it vertically. I guess, allowing for more upward air movement along the mounting surface. There is plenty of room in the Supermini for a vertical mount and I sourced a finned heat sink to improve the relay's performance. So when all of the parts arrive, I should be ready to go.

Took the mechanical relay off. Made a mounting bracket that can hold two SSRs for where I finally install a PID controller. Installed the AC 120Vac 25A SSR with a heat sink (because it helps and there is room). Heat is generated when the boiler is first heating up, but the SSR and sink stay cool after that. All is running very nicely. The pressurestat with the mechanical relay removed seems to be functioning very well.
