EMB145 flight crew reports bld over temperature during climb out. When icing is encountered flight descends. When numerous airfoil de-ice messages appear flight crew elects to divert to nearest suitable airport for maintenance.

Narrative:
While climbing through FL190 to FL280; EICAS detected bleed 1 overtemp. Followed QRH procedures -- stopped climb at FL250; deselected bleed 1; and turned xbleed to 'open.' QRH also directs that 'if in icing conditions; refer to single engine or single bleed operation in icing conditions procedures.' since we weren't in icing conditions at the time; I quickly scanned the procedure 'just in case' and noted that it would require a descent to 15000 ft and/or exit icing conditions. We contacted dispatch to receive new performance/fuel burn numbers. About that same time; center informed us to expect light rime icing. The aircraft detected ice shortly thereafter; and we started the descent. While descending; wing anti-ice fail (again); and bleed 1 overtemp red warning (though it remained deselected). Bleed 2 temperature was increasing as well. Decision was made to divert. Contract maintenance was called. They cleaned a filter and we did an ice test. Ice systems checked out normal; and flight continued uneventfully at 6000 ft.

Title: EMB145 FLT CREW REPORTS BLD OVER TEMP DURING CLIMB OUT. WHEN ICING IS ENCOUNTERED FLT DESCENDS. WHEN NUMEROUS AIRFOIL DE-ICE MESSAGES APPEAR FLT CREW ELECTS TO DIVERT TO NEAREST SUITABLE ARPT FOR MAINTENANCE.
Narrative: WHILE CLBING THROUGH FL190 TO FL280; EICAS DETECTED BLEED 1 OVERTEMP. FOLLOWED QRH PROCS -- STOPPED CLB AT FL250; DESELECTED BLEED 1; AND TURNED XBLEED TO 'OPEN.' QRH ALSO DIRECTS THAT 'IF IN ICING CONDITIONS; REFER TO SINGLE ENG OR SINGLE BLEED OP IN ICING CONDITIONS PROCS.' SINCE WE WEREN'T IN ICING CONDITIONS AT THE TIME; I QUICKLY SCANNED THE PROC 'JUST IN CASE' AND NOTED THAT IT WOULD REQUIRE A DSCNT TO 15000 FT AND/OR EXIT ICING CONDITIONS. WE CONTACTED DISPATCH TO RECEIVE NEW PERFORMANCE/FUEL BURN NUMBERS. ABOUT THAT SAME TIME; CTR INFORMED US TO EXPECT LIGHT RIME ICING. THE ACFT DETECTED ICE SHORTLY THEREAFTER; AND WE STARTED THE DSCNT. WHILE DSNDING; WING ANTI-ICE FAIL (AGAIN); AND BLEED 1 OVERTEMP RED WARNING (THOUGH IT REMAINED DESELECTED). BLEED 2 TEMP WAS INCREASING AS WELL. DECISION WAS MADE TO DIVERT. CONTRACT MAINT WAS CALLED. THEY CLEANED A FILTER AND WE DID AN ICE TEST. ICE SYSTEMS CHKED OUT NORMAL; AND FLT CONTINUED UNEVENTFULLY AT 6000 FT.
