Heimweiler lies at the edge of the North Palatine Uplands along Landesstraße 182 (Kirn–Meisenheim) and on Kreisstraße 71, which links the two centres of Heimberg and Krebsweiler together.

Like most of the district's places, Heimberg's and Krebsweiler's foundings might have come about during the “opening up of the newer settlement area” (7th to 12th centuries).

After that comital house died out, the Amt of Naumburg passed to joint administration under the Electorate of the Palatinate and the Margraviate of Baden.

Economically, the villagers of Krebsweiler and Heimberg turned to Kirn, where, to support the town's market, the so-called Zollhafer (a toll in oats) still had to be paid in 1579 to the Lords of Steinkallenfels.

After Napoleon’s downfall and the implementation of a new administrative order by the Congress of Vienna, this local administrative arrangement continued in 1815 as an Oberschultheißerei, but in the 1820s, the seat was moved back to Becherbach, which thereafter stood as the seat of the Hesse-Homburg Bürgermeisterei (“Mayoralty”) of Becherbach in the Oberamt of Meisenheim.

Both Heimweiler's constituent communities remained in the Amt of Becherbach, which became part of the Bad Kreuznach district in 1932, until 1940, when it was dissolved.

With Heimberg, the name prefix Heim— corresponds with the name forms Heym, Heien, Hen, Hahn, Haan and so on, and goes back to the Old High German hagan ( = —hagen) in the meaning “forest” (Hag = wooded lot), and indeed Hain is still a German word that means “grove”.

In the Hesse region, the Grebe was the reeve or village head, quite unlike the Modern High German meaning of Krebs, which is “crab” (the Online Etymology Dictionary declares that the Old English word gerefa, from which sprang the Modern English word “reeve”, has “no known cognates”[7]).

In the local region, the old words Heimberger or Heymbürge had the same meaning (see the German Wikipedia article “Heimbürger”).

The figures for the years from 1871 to 1987 are drawn from census data:[9] The greater part of Heimweiler's population is Evangelical.

The municipality's arms might in English heraldic language be described thus: Per fess abased sable a fountain on a pedestal all argent, and chequy of eighteen azure and Or.

After consent by the state archive, the Ministry of the Interior in Mainz had then granted approval for Krebsweiler to bear its own arms on 1 July 1966.
